Image Classification with Convolutional Neural Networks

Another one on our list of GitHub data science projects for beginners focuses on image classification using CNNs (convolutional neural networks). CNNs are a subtype of neural networks with built-in convolutional layers to reduce the high-dimensionality of images without compromising on the information/quality.

Problem Statement

The aim of this project on data science is to classify images based on certain features using convolutional neural networks. On completion, you will develop a deep understanding of how CNNs proficiently work with image datasets for classification.


In this project, you can use a dataset of Bing images by crawling image data from URLs based on specific keywords. You will need to use Python and Bing’s multithreading features for the same using the pip install bing-images command on your prompt window and import “bing” to fetch image URLs.

Step-by-step Guide to Image Classification 

  • You will start by filter-searching for the kind of images you wish to classify. It could be anything, for example, a cat or a dog. Download the images in bulk via the multithreading feature.
  • The next is data organizing and preprocessing. Preprocess the images by resizing them to a uniform size and converting them to grayscale if required. 
  • Split the dataset into a testing and training set. The training set trains the CNN model, while the validation set monitors the training process.
  • Define the architecture of the CNN model. You can also add functionality, like batch normalization, to the model. This prevents over-fitting.
  • Train the CNN model on the training set using a suitable optimizer like Adam or SGD and evaluate its performance.

Some relevant GitHub repositories that will help you classify images using CNN are listed below.

Sentiment Analysis on Twitter Data

Twitter is a famous ground for all kinds of data, making its data a good source for practicing machine learning and data science tasks.

Problem Statement

It has become necessary to analyze the sentiment behind things posted online. Following the same line, this project aims to study and analyze the sentiments behind the most popular social network, Twitter, using NLP (natural language processing). 


In this GitHub data science project, you will gather Twitter data using the Streaming Twitter API, Python, MySQL, and Tweepy. Then you will perform sentiment analysis to identify specific emotions and opinions. By monitoring these sentiments, you could help individuals or organizations to make better decisions on customer engagement and experiences, even as a beginner.

You can use the Sentiment 140 dataset containing over 1.6 million tweets. The tweets Link to the dataset: Sentiment140 dataset.

Step-by-step Guide to the Project

  • The first step is to use Twitter’s API to collect data based on specific keywords, users, or tweets. Once you have the data, remove unnecessary noise and other irrelevant elements like special characters. 
  • You can also remove certain stop words (words that do not add much value), “the,” “and,” etc. Additionally, you can perform lemmatization. Lemmatization refers to converting different forms of the word into a single form; for example, “eat,” “eating,” and “eats” becomes “eat” (the lemma).
  • The next important step in NLP-based analysis is tokenization. Simply put, you will break down the data into smaller units of tokens or individual words. This makes it easier to assign meaning to smaller chunks that constitute the entire text.
  • Once the data has been tokenized, the next step is to classify the sentiment of each token using a machine-learning model. You can use Random Forest Classifiers, Naive Bayes, or RNNs, for the same.

Music Genre Classification with Machine Learning

This is among the most interesting GitHub Machine Learning Projects, data science projects for beginners. While it is a great project, it is equally challenging as getting a proper dataset would be a very time-consuming part of this project, given it’s all music!

Problem Statement

This unique GitHub Machine Learning Projects is aimed to help you learn how to work with non-standard data types like musical data. Further, you will also learn how to classify such data based on different features.


In this project, you will collect music data and use it to train and test ML models. Since music data is highly subject to copyrights, we make it easier using MSD (Million Song Dataset). This freely available dataset contains audio features and metadata for almost a million songs. These songs belong to various categories like Classical, Disco, HipHop, Reggae, etc. However, you need a music provider platform to stream the “sounds.” 

Link to the dataset: MSD.

Step-by-step Guide to the Project

  • The first step is to collect the music data. 
  • The next step is to preprocess data. Music data is typically preprocessed by converting audio files into feature vectors that can be used as input.
  • After processing the data, it is essential to explore features like frequency, pitch, etc. You can study the data using the Mel Frequency Cepstral Coefficient method, rhythm features, etc. You can classify the songs later using these features.
  • Select an appropriate ML model. It could be multiclass SVM, or CNN, depending on the size of your dataset and desired accuracy.
