- Practicing with datasets and an online github profile are helpful in showcasing your skills
I joined Analytics Vidhya as an intern last summer. I had no clue what was in store for me. I had been following the blog for some time and liked the community, but did not know what to expect as an intern.
The initial few days were good – all the interns were smart, motivated and fun to be around. We played cricket in office, did internal hackathons over weekends and learnt a lot of data science. But, if there was one defining moment for me in the internship – it was when I realized the impact Analytics Vidhya was having in data science community.
I saw thousands of people following Analytics Vidhya religiously. I saw people looking up for guidance in our meetups and hackathons. I saw people transitioning their careers because of the resources we provide them. That is when this good internship transformed into a mind blowing experience.
That is the day I decided that this is my calling. It just felt that this is what I would want to do daily.
Why create this learning path?
Among various resources on Analytics Vidhya, learning paths are special. The amount of effort and thinking they need is tremendous. The number of drafts they undergo is mind-boggling. But, the kind of impact they create for our audience is HUGE. That is why I decided that I will create a learning plan for 2017 for all our followers.
We created a similar plan for 2016 and we saw transitions happening by people following this learning plan. This time we have created a much granular and a more detailed learning plan. The sole aim behind creating this comprehensive plan is to create a much bigger impact for our followers this year.
Who should use this learning path?
This learning path would be extremely useful for any one who wants to learn machine learning, deep learning or data science in this year. If you plan to wait for a year, we will publish something similar in 2018 as well 🙂
But, for the people looking for action this year, this framework and plan of action should be extremely useful. Whether you are a complete fresher or a transitioner or you are looking to up-skill yourself, this plan should give you the necessary direction.
We published a similar plan in 2016 and we saw followers making transition by simply following the plan. This year’s plan is more nuanced than last year’s one – so if you plan to pick up / improve data science skills – this plan will guide you through the journey.
How can you use this learning path?
In creating this plan, we have removed the confusion from the process of learning. The biggest challenge which people face while learning is not dearth of learning material – but too much of it. You are not sure where to start learning, what to practice, how much time to spend on a concept, where to get the useful resources etc. For most of the beginners, this becomes overwhelming and they simply drop out before even learning a single skill.
This plan takes this confusion out. This path contains both theoretical resources as well practical examples. We have also provided you with resources / tests to apply your learning and benchmark yourself. As part of this plan, you will apply the concepts you learn on real-world problems and gain hands-on experience.

4. Transitioner’s path for 2017
Let me start by giving you the bad news – it is not going to be easy to transition in data science. Also, the more your work experience, the more difficult your transition would typically be. You would need a strong resolve – there will be times when you might question, whether this is the right domain for you.
The good news is that once you get your first break in the industry, there is no looking back. Also, because of the salary differential from other industry, you may not need to compromise on your earnings during transition.
To achieve your goal all you have to do is follow this learning path diligently. We have covered all the skills, techniques you need to gain to take your first steps in data science.
The Ultimate Path for transitioners
Simply put, if you are looking for a transition under a year, you will need to learn everything we laid out for the beginner above. Additionally, you will need to carve out additional time to showcase your skills. You will need to overcome the doubts of your potential employers through your projects and work.
I am sure you are beginning to understand why transition is not an easy thing.
Structure for your 2017 journey:
The structure of the path is similar, but you will need to accelerate your learning in the first half of the plan. Start by going through this article and go through a few success stories to understand what a transition would entail.

Structure of intermediate path for 2017:
5.1: Assess your technical & structured thinking skills – Jan 2017
The first step in creating your learning plan is to benchmark yourself on various skills – both technical and structured thinking. You can go through the skill tests on Analytics Vidhya to judge whether you need to review the old material. If you do well, go ahead with acquiring new skills. Else, go back to practice for some more time.
If you feel the need to go through the old material once again, refer to beginner’s path which contains various useful resources.
Skill tests:
- Statistics 1 & Statistics 2
- R for Data Science
- Python for Data Science
- Machine Learning
- Regression
- Tree-based algorithms
- SQL
Structured Thinking
- Articles (mandatory) – These articles will guide you to structure your thinking to solve business problems efficiently.
- Competitions (mandatory): Check out strategic thinking problem to test your structured thinking. Also, keep an eye on business case studies as they help in structuring your thought process.
5.2: Few more ML algorithms – Feb 2017
There are a few specific machine learning algorithms, which come in handy while solving specific problems. For example, try solving online click prediction on large data sets with out applying online learning algorithms and you would know what I am talking about. Here are a few advanced ML algorithms you should learn this month:
Online Machine Learning
Vowpal Wabbit
FTRL- Algorithms
Exercise: Practice on one of the old Kaggle competitions or open click through rate data sets as provided by Criteo.
5.3: Pick up a data visualization tool (March 2017)
Ideally you should pick up D3.js for sure and either one of QlikView and Tableau. While D3.js provides the most flexibility, QlikView and Tableau are both handy for creating dashboards or less complex story creation and narration.
Topics to be covered:
- Interactive Visualization using d3.js (3 weeks)
- Creating Visualizations in QlikView (1 week)
- Creating Visualizations in Tableau (1 week)
Interactive Visualization using d3.js
The reason d3.js is not so much popular among Data Scientist is because it requires an entire different skill test like HTML, CSS, Javascript which is not typical of a Data Scientist.
But knowing D3.js can take your story telling capabilities to a different level. You can create non-static Interactive graphs embedded right in a browser for a much richer experience. Below are the list of resources to master d3.js
- Course Data Visualization and d3.js : This is an excellent course provided by Zipfian experts on Udacity and a part of Facebook’s Data Analyst Nanodegree program.

Topics to be covered: Reinforcement Learning (Theory)
5.7: Web frameworks & Cloud Computing (November 2017 – December 2017)
Web Frameworks
Now that you know machine learning well, you might want to apply it to web products. What you need to learn is a working knowledge about web frameworks. Web frameworks allow you to quickly build and prototype web based products, with out getting into the complications of coding.
Given that you would already have working knowledge of Python, you can choose any of the Python based web frameworks. I would recommend Flask for its simplicity. Flask is a simple and light web framework, which should serve your needs well. If you are looking to build a complex web product, you might want to consider Django as well.
Resources for learning Flask:
Exercises:
Additionally, you should do a side project to merry your machine learning skills and web development skills. You can build a simple web application where users can upload pictures and find which make and model the car is. Or may be tells people about their age.
Cloud computing
Now that you know how to build web applications, you should also get your hands dirty on cloud computing. A few popular platforms are Amazon Web Services (AWS), Google Cloud platform and Microsoft Azure.
Each of these platform provide extensive documentation for their offering. If you have to pick only one – AWS is the way to go because of its popularity, wide spread use and comprehensive offerings.
End Notes
I hope you found this learning path helpful. I have made it as specific and comprehensive as possible. If you think I have missed out on any specific areas or resources, do let me know.
If you want to progress in your data science journey all you have to do is choose your category and follow the learning diligently.

I am a perpetual, quick learner and keen to explore the realm of Data analytics and science. I am deeply excited about the times we live in and the rate at which data is being generated and being transformed as an asset. I am well versed with a few tools for dealing with data and also in the process of learning some other tools and knowledge required to exploit data.
Hi NSS/Kunal, The effort you guys are putting to enable the data community onto the data science track is commendable.My best wishes to you. Vishwa
Thank you Vishwa. This is what we love to do :)
Hi, I am a 30 yrs with professional experience of 6 yrs in retail Banking , I have joined Jigsaw with Life time Membership.. I give 2 hrs daily to the Data Science and big data. I want to ask what extra i will do to change my Industry from Banking TO Analytics field and what would be my Starting Package if Now i am getting around 7 LPA
This article, I can safely say is the best I have came across till now. I have been tirelessly searching to come up with a practical scheme (I'm an undergrad at Kharagpur) to prepare myself for the data jobs. NSS I can only imagine the hard work you guys have put in to come up with such an elaborate and all-embracing article. I'm an avid follower of AV but was always a bit indolent to write comments, but not praising this would be lethal, I guess :P . Keep up the wonderful work. Thanks a ton for this brilliant write up! Jayant PS : Your Connect with: FB is not working I believe
We are glad to be of help Jayant. This is what we love :)
Hi Jayant, You can now share this on FB, It's working.
Courage, you have to train and have skills !. Companies value what you know how to do. Here, you will find a great plan to be very employable. Lots of energy and luck!
Stands the reason why AV is the google for Data Science.
Not yet, But we aim to . Happy Learning :)
Please, Please provide a printable pdf format of this article. What an article! Kudos to AV and NSS. Thanks and Regards.
Thanks AV, for such a comprehensive guide for guys like me who want venture into the field of Data Science but has no idea as to where to actually begin, considering the vastness and exponential growth of the field.
You are welcome Sachin. Share and spread the world . Help more people like you . It is more fun learning in a group. :)
Excellent Article. Thanks you very much for sharing.
You are welcome. It is more fun when you learn in a group. Spread the word and keep learning. :)
Great article and very promising for data science newbies and experienced professionals. Thank you. However, when I look at the courses you suggest and the timelines you propose, there seems to be a disconnect. For example, in 3.2: Basics of Mathematics and Statistics, you have Descriptive Statistics – 1 week, but the course you propose has a timeline of 2 months. The second course. Introduction to probability – The science of uncertainty, has last been offered in 2015 and is archived since then and not available. Intro to Inferential Statistics from Udacity is a 2 months course, again you have it down for 2 weeks. What am I missing? Thank you.
You are missing the point that with the pace given on udacity, you will end up with hardly 5 courses and probably nowhere after an year. And since I have done most of the courses myself in the deadline mentioned in the article, I think it is doable by all. More for a newbie and just an year and an aim of an internship/job, you need to speed things up a lot. Hope I made myself clear.
Also, I have updated the probability course with the new session which starts today Jan 17, 2017. Happy Learning.
Thank you NSS for publishing this learning path. I just started exploring data science and faced the challenge of chalking out a learning strategy. Your article has come just in time !
It is more fun when learning happens in a group. Spread the word and Happy Learning :)
Since last a month I'm regularly following Analystvidya @Facebook,, I found most of the posts quite resourcesfull,, Data Science for non-mathmetics is really a wonderful concept,, being a IT professional I'm also looking forward to learn more about it.
You have come to the right place Rajesh. Happy Learning :)
Nice Article. Very helpful for data scientists. Appreciate your effort
Thank you shankar. Spread the word. Happy Learning. :)
Hi, I am an undergrad(final year) from BITS Pilani. After years of competitive programming , I have decided to dive in the interesting field of Machine Learning. I must say this is by far the most helpful article for beginner like me. Can you also share with us some preparatory guides which would help in landing me a job in companies like Goldman Sachs .
solid piece of work, thanks
Thank you badri. Share the word and stay connected.
Thanks for your great insight and generosity! My best wishes.
Thank You Renato.
Question about the math required for this course of study: most graduate degrees in statistics have calculus prerequisites (including multi-variate) that must be completed before acceptance into their programs. I'm told a lot of the math behind certain areas of statistics is based on integrating functions, and a knowledge of calculus is necessary for their understanding. Do you feel Calculus would be a useful and necessary addition to your learning plan?
Thanks ilan for pointing that out. Personally, I have felt that to be a good Data Scientist you do not need the academic rigour of statistics. High school calculus to the point of dealing with ODEs, Partial derivatives are enough to understand most of the statistics topics. And in such a short duration, Calculus might not have fit in. But it is a useful skill though. Happy Learning.
Is there a way we can have an account in the weebsite in order to bookmark our favorite articles ? keep the good work.
Well, you dont need a better guide than this to proceed with a systematic approach to become a data scientist.Kudos to the team and the author. Thanks
Thank you Bala. This is what we love. Happy Learning :)
So beautiful! I looked all around quora and a multitude of websites and what not, you name it! Don't get me started on the thousand dollar bootcamps. This is amazing work guys!
Thank you Roshan. Happy Learning.
Amazing Learning path! Thank you so much for this. Although I came to a standstill at one point.. The course for probability (beginners path), the course content will be coming out over the weeks.. Unfortunately I won't be able to do that course in the prescribed 2 weeks time because the course content of the whole course will be coming out only by May of this year. How should I proceed along with this??
Thank You Arjun for pointing it out. The course was mentioned because it was accessible even in the archive form. But edx has restarted the course so i will update the link once again as soon as i find the entire course in a single go.
This is a brilliant piece of article. Thank you for the hardwork
Hi NSS i am a fresher from mechanical Engineering, actually so long i was learning data science by my own i mean no schedule from others but it gave me a clear picture of what all the things needed and in proper order, actually i am doing coursera's data scientist toolbox course along with the practical exposure in datacamp, in coursera they introduced the tool R in the beginning is it worth to learn in that way? And I personally feel that coursera's exploratory data analysis course didnt give much things in practical way the instructor just fliping with concepts and a course in udactiy called data analysis in R gave a very good practical exposure to ggploting system. Once again Thank you soo much for your plan it will help thousands of people like me.
Hey NSS, First of all, I want to thank you and AV for such an helpful material for transitioning to Data Analytics as a career. Now, I am going through Probability course, and they released just two weeks material till now which I have completed, but I want to complete the whole course before going further. So, Can you please provide the link for Archived course, It will be really helpful. Thanks
An amazing article related to data science learning. Python is indeed an excellent programming asset that helps in building up the network of data science as it helps to program all latest devices. The code format is simple and tricky at the same time, so a lot of patience is required to learn it. But once the knowledge of Python is acquired, things like IoT and Cognitive Computing become easy and thus helps the progress of data science.
Hi NSS, Actually I started this course last year and so I was following the last year's plan, but unfortunately due to my work pressure, I couldn't complete it in last year. Some things seems to be same but some are different. Is it wise to still follow the 2016 plan, as I have already completed 50+% of probability and statistics from Khan Academy ?
Yes, you can continue with the same. Just look out for the differences in terms of new additions to the topics to be studied. For example, we have added Re-inforcement learning this year to our path.
NSS, You've done great job in compiling the best for us to achieve our goals. This will save us loads of time. But since I'm only familiar with R, intermediate and advanced topics do not have R as base language to understand the concept, for e.g. most Udacity courses are based off Python.
Hi NSS, I was following the data science learning path for 2016, but couldn't complete it last year. I have completed - Descriptive Stats, Inferential Stats, Algebra, but couldn't complete Probbaility ( from Khan Academy ) although I have completed almost 60% of it. Can you please advise, if I should carry on with the Khan Academy course or should I start eDX one, which you have pointed for 2017 learning path ? Regards Sakshi
Great Job NSS in compiling this learning path. Just one small suggestion from my side that if possible, please include the meetups information related to data science related fields, that would offer great learning and networking opportunities to one and all on this path. Thanks and Regards, Deepashu
Hello NSS, I have 4 projects(created one year ago) done but I got to know about github from my friends.How do I post it that it was done in previous year?
Brilliant peace of work. Appreciate your efforts. Bless you :)
Hi NSS: One quick question, we don't have to learn both R and Python in details, only learning one in details is suffice, I guess? I, myself is a SAS advance programmer, now currently trying to grow my skills in DS. However my plan is, as I have some exposure with python, to learn python in details and just do nothing or perhaps some basics in R. What would be your advise for that? thanks,
Yes learning one is enough if it's python. Otherwise, if you are into R and deep learning stuff ,python becomes a must.
Hi Team, This article is exactly what I was looking for. You have made so many lives easier !! Great work!!
Very useful information NSS. Keep it up !
Hi, is the path for beginners and transitioners same or different because I don't see any separate links for them.
@Munish.... The links are the same but the timeline is different.
Hi, I am starting with data science course. Now I have two choice to start with: 1. Data science specialization from John Hopkins University on Cousera 2. The Analytics Edge on Edx I am little confused which one to do first
@Munish..Though i am very late to replying this. I would go with the coursera's course.
Hi, NSS: Your article is really helpful. It seems that there is a wrong link in the sector 3.3 Feature Selection/ Engineering, the "Blog – A Comprehensive Guide to Data Exploration"'s link is point to another pdf file.
@minxi...The link has been updated. Thanks for pointing that out.
Where would you suggest a transitioner starts who is also mathematician?
Hello NSS, Seriously commendable efforts. What keep your guys ticking? Whatever, it will help! I am from a pure health science background, who had her hands in lots of things. The information out there is overwhelming. Your streamlining efforts are very helpful Thanks tons! Toast to sharing!!
Hi NSS, Thank you for providing such a clear guide, is has been very helpful in improving my analytic skills. Just a small confusion found in the article: Under feature selection / engineering, the first link to a blog article actually get me to the book 'python for data analysis'. Wondering if this is intentional?
@Ross... The link has been updated. Thanks for pointing that out.
Great work pulling this together! Really appreciate it!!
Is it possible to do edx courses at our own pace??. As I have noticed that not all the units are uploaded at once.
Looks like the book "Mastering Feature Engineering" is not available anymore?
One of the most insightful and most comprehensive Data Science blog to cover all knitty gritties of Data Science Universe.In addition to this,the recently conducted Datafest AV 2017 , Mumbai region was one of the best opportunities for aspiring Data Scientists like us to explore more into the industry.Looking for more such meetups on Data Analytics and wishing you all a great luck ahead.
@NSS You are a God sent, I would like to thank you with all my heart , this is by far one of the most descriptive article I could find on internet for career explorers like me, thank you so much my friend, you are a blessing for the freshers.
Thanks for pointing out some of the differences between beginners in data science (like those who have no prior experience) and more intermediate members (like those who are already comfortable with building predictive Machine Learning models). I feel like knowing where you stand would definitely help you know what programs and learning paths would be the most useful for you to follow. A breakdown like this could be a useful tool for a business to help them organize their training program.
is there any already created Study Group?
Thank you very much for this article. However, do you have a mistake when putting the link on the "Feature Extraction/Engineering" part of the beginners' path. It the same book of the previous link and not a blog as you said.
@Quoc Anh Trinh.....Thanks for pointing out. The link has been updated.
Hello NSS, Thanks for this wonderful plan,however I have some query .As you have mentioned machine learning by Andre Ng, he recommends using Octave.But we are learning python/R ,so how should we follow up on his classes?
@Veena... andrew ng's course is recommended for the theoretical knowledge. Also, if you wish to you can attempt exercises in R and Python but you won't be able to submit the assignments.
NSS, Your plan helped me a lot to get a direction on building my Analytics quotient. I find the Probability course from edx is very theoretical and of course I am struggling with the course :(. If you have any alternate equally effective Probability course in mind, do share your recommendation. Thanks in advance.
same here but i finished it 2 days ago and it was a struggle
What a great work for us new beginner! Thanks so much for your article!
Hi NSS, you have mentioned probability class from EDX to finish in 1 week,It would be great help if you can guide me how we can finish it in 1 week in most efficient way.I have started that class and was only able to cover half in 1 week. Regards, Aradhana
Thanks a lot for the information. its highly beneficial.
why isn't hadoop listed here sir? shouldn't it be mentioned. your views please ?
This is great and helpful information. Thank you for laying out these learning plans. I'm hoping to follow these plans and transition into data science after having taken time off from working in database development and having a baby. Could you please advise on what a recommended computer/laptop specifications would be to learn data science? I would like to make sure I have adequate computing power. Thank you!
Hello sir, i had a query. The introductory course of R which you have mentioned, after that do we need to do intermediate R course of datacamp?
Very good article. I am interested
Full fledged Plan. Great Plan. Nice Paths with complete details of actual resources for each concept. Huge Thanks. Still basic doubt floating in my mind and made me to write this comment. Please help. For beginner, to get job/internship, Is not required to have big data skills, deep learning skills and cloud computing? Should I go without all this? Will it work or I need to follow intermediate path also after beginner one?
Data Science Ecosystem is holistic and complex , It needs a lot of focus, discipline and commitment to do and achievement along with our routine professional and life cores . I am doing bits-and- pieces since 2 yrs (not disciplined way ), its over whelming and huge growth and career path is remarkable for those who do it hard way. Thanks for Analytics Vidhya for helping 100-1000 students who dream and can make their BIG career in their life and in Data Science
This article is by far the best i came across.I was really finding a direction to go for in data science but possibly could not find one unless i visited this website.I am really thankful to you for this. :) :)
Wow, this is easily the most comprehensive learning plan available. The biggest challenge is now to prioritize this list with other tasks and start learning. Any tips from others who have successfully covered this kind of learning plan on their own would also be helpful.
Thank you! This is something what i am looking for.As i am a beginner i will definitely refer this.
This is the best article I have read till now on Data Science. I am going to start learning Data Science according to this schedule. Thank you!
guys, the link for (Exploratory Data Analysis) leads to( A Complete Tutorial to Learn Data Science with Python from Scratch ) so here is the coursera link (Exploratory Data Analysis) https://www.coursera.org/learn/exploratory-data-analysis#
I just want to send my sincerest gratitude to you for taking the time to put this together. Incredibly helpful and provides a clear path to learning data science independently.
The learning path seems to be relly good.But I have a confusion in learning the initial topics of Mathematics ans Statistics.There are severel online courses in Udacity,edX etc.. that are specifically titles as Statistics for R,Data Science. Which course should I follow??Either topics in the given learning path or that one... :( I wish to start my learning according to the path mentioned as early as possible. Help me get rid out of these confusion.
For Linear algebra, I would recommend going through following youtube playlist as well. It's a very small series explaining linear algebra in graphical way. https://www.youtube.com/watch?v=kjBOesZCoqc&list=PLZHQObOWTQDPD3MizzM2xVFitgF8hE_ab
Hi, i am software QA for past 4 years and i am interested to learn data science. Is this transition possible from QA to data science. I pursued masters from Electronics. Please suggest
Hi kunal&Team, This is madan here.I am starting with the same plan now (september 14).So some of my questions are 1.If there is some other plan next year would it be too much of a difference? 2.Would it be even more updated? 3.Would I be able to transist smoothly to the 2018 plan? 4.If so when will the plan be Released?
what if I started this comprehensive plan lately??? does the next year plan will vary greatly from this plan
so great study plan! and now did you got it? I also want to study machine learning from now. thanks a lot your plan
hi sir I was reading this amazing article posted on your website as i have knowledge of python programming and regular expression but not with the data science and i know it would be pretty easy for me to learn that libraries and i was doing the same by following your systematic approach but when i come to know about your carrier page (Get Hired ) there were only job for the experienced guys now how would i get this experience(industry experience) and who would give me job as a fresher in data science
Hello, I am a BCA graduate and currently doing MCA. I am interested in Bigdata and Cloud. Plz tell me which course will be good for me. Thanks.
Hi NSS, let me begin by commending your efforts on the article. Though being a transitioner there was a little bad news for me as you also mentioned. I have a 10 years of C++ industry experience, but i am really eager to upskill my resume and I am greatly attracted with the kind of work folio a data scientist has. Do you think this transition at this point in my career would be a right move ? I am a little confused , which i think is okay to be at some time .. Looking forward to a motivational answer :-) Thanks
Is it required to add up SQL along with the above path??
I loved the article so so so so much it is very helpful , thank you
Was thinking of starting this but it's so close to 2018 is there another plan coming? Thanks!
Hi, Very useful post indeed, can we have something on AI with similar format. Thanks a lot for preparing and posting such useful content
Amazing resource, shame I have only just found it! Since 2018 is just around the corner, when may we expect an updated version?
hi, when will the new learning path wil come
As a self-identified transition/intermediate leaner, I have been trying to find a path of learning more than a year :( frustrated and overwhelmed by the sea of tutorials, blog posts online. Yet none of them solve my fundamental problems, especially I am working full time as Product Manager in enterprise software domain. Now, ,I have found the map/directions and I know I just need to follow the path and get to my destination :) Thank you very much! And please post the 2018 version soon! Best Siyun
Hi, NSS! Thanks a lot for this indeed comprehensive plan. I got stuck in Probability Course from edX because it seems to me too rigorious with so many topics. Is it really worth to get through all of the topics or better to focus only on fundamental ones? I'm absolutely newbie in Data science, could you explain please how is it better to move at faster pace?
Hi, This plan is really incredible and elaborate! Thanks a lot!!! I plan to follow this from 2018. Do u have any updates for 2018? Cheers from Georgia!
Hi! Are you planning to post a learning path for 2018 ? Thank you a lot!
This is exactly what I've been looking for, thank you for that. I have modified the plan for 2018 and will use that, Wondering if/when the 2018 plan will surface? (in case there is any essential new learning to be had). thanks
I am patiently waiting for 2018's version so I can start from day one! This is indeed comprehensive. Great work.
Hi you can find the 2018 version here. https://trainings.analyticsvidhya.com/courses/course-v1:AnalyticsVidhya+Python-Final-Jan-Feb+Python-Session-1/info

Found this to be very Useful. Thank NSS. But is already 2018, can you post the 2018 version for those of us who wants to start this year.
Can you publish the learning plan for 2018 pls?
Can you please publish the learning plan for 2018?
Hello NSS/Kunal, I just got the chance to view this wonderful detailed article. Can I follow the same steps from now onwards or Do you have any learning plan for Data science in 2018..?
This is great, thank you. Are you still planning to publish a study plan for 2018? Eager to get started but may wait for the 2018 plan if it's on the way.
waiting for 2018 plan when it's going to be published??
Hi, NSS. This is a valuable guide, thank you! Sadly, I've just now found it - in 2018. When can we expect the new 2018 guide to come out?
Will there be an update in 2018 ?
Hi NSS, You are awesome and Thank you so much for this article. I am pursuing Data Scientist course from Jigsaw Academy starting from this January 2018. Can I follow same learning path for this year also? I am in transitioners group and Having 5+ Year of experience. Please let me know Thanks and Regards Saurabh
Hi, Thanks for sharing such a great article with us on Data Science we are glad to read this Data Science information
Hi, Thanks for sharing such a great article with us on Data Science we are glad to read this information on Data Science
It's awesome when 2018 plan will be published ??
Great article , when can we expect an update for 2028 ?
Hello, I want to ask about beginner's path-probability. It was said that we need to learn about this topic from edX. When I go to edX courses about probability,it has 10 units in that course and it takes almost three month to learn all the unit. But in the learning path for beginner the time for learning about probabilty is only 2 weeks. Do we have to cover the 10-unit course about probability in edX or maybe we just need to learn unit 1?
This article is the most germane article I've ever come across and it meticulously integrated with all the elements. Thank you very very much.
Hi, thank you for this, that´s exatly what I was looking for! I am a beginner, and I have learned a little of python. My doubt is how much programing is required in Data Science? How deeply should i dive into this? Thank you.
Hi, The course on probability is 18 weeks long and specifies you to take 12 hours in a week.Can you please suggest a sub.Thanks.
How about dynamic dates in the article!!!
Nice post Thanks for charing huge information on Data Science
Wow! That's some great informations you've brought there together and in my new position I'm going to need it. I just wanted to thank you for the time and effort you've put into this and wanted to tell you that I'm going to put it to good use in our company :)
I am glad the plan is of help Emilia. Happy Learning.
Thanks Emilia,
Hi NSS/AV team, A very profound article for all sort of data science venturers. it contains all the necessary things to be considered for growth in data science domain. thanks for sharing such information and keep up the good work.
