Beginner Libraries Listicle

This article was published as a part of the Data Science Blogathon.

Introduction

The main motto of this post is to give a brief about these libraries and how useful it is in your career. Machine Learning is tough to learn; when it comes to data preprocessing, algorithms, and training models. But, it’s not the same after the growth in technology and the availability of both low-code and no-code machine learning platforms and libraries, and limitations to use and apply ML models in applications is less. 

These libraries help the user to user-defined functions that take care of preprocessing and quickly run the ML models. Lines of code is less by using these libraries. The no-code platform offers drag and drop, which is an easy way to run the ML model but lacks in flexibility. On the other hand, low-code ML is better, which offers both flexibilities and ready-to-use code. Without further ado, let us dive in and know about these libraries and their functionalities.

 

Low Code Libraries

Pycaret

I have been using PyCaret for the last four months and admit this library is unique. By using this training, testing and deploying an ML model is simple. They also provide tutorial notebooks for Regression, Classification, Clustering, and NLP, and their documentation is good.

PyCaret is an open-source, low-code machine learning library in Python that automates machine learning workflows. It is an end-to-end machine learning and model management tool that speeds up the experiment cycle exponentially and makes you more productive. — https://www.pycaret.org.

PyCaret Functions

  • compare_models() – trains all models available in the library, use default hyperparameters, and performance using cross-validation. MAE, MSE, RMSE, R2, RMSLE, MAPE are Regression metrics. Accuracy, AUC, Recall, Precision, F1, Kappa, MCC are Classification metrics.
  • create_model() – creates a single model which we specify using default hyperparameters and evaluate performance.
  • tune_model() – model is passed as estimator and tunes hyperparameter. uses random grid search with pre-defined tuning grids that are customizable.
  • ensemble_model() – accepts trained model, and returns a table with k-fold cross-validated scores of evaluation metrics.
  • plot_model() – used to evaluate the performance of trained ML model.

Features of the latest version include:

  • Tuning of hyperparameters of the various model on GPU: LightGBM, XGboost, and Catboost.
  • Updated deploy_model function to support for deployment on GCP as well as Microsoft Azure.
  • Plot model function included with ‘scale’ parameter which you can use to control and generate high-quality plots.
  • Included Boruta algorithm for enhanced feature engineering.

They provide well-designed tutorials. To know more about Pycaret.

 

H2O AutoML

It is another open-source tool, useful for those starting ML without the experience of coding. It has a combined interface for multiple models and algorithms that simplify the process of training models. With this, you can train models in less time and a few lines of code without in-depth knowledge of ML algorithms. It supports both Python and R languages, which makes it appealing to the newbie as well as the experienced.

For beginners, it helps automate preprocessing, training, validation, and fine-tuning models. Assist advanced users in data engineering and stacking different models. For these reasons, even Kaggle competitors use H2O AutoML. When compared with PyCaret, one should write more code using this if you are not using the web interface. Despite this, it is still easier to train a model by using H2O AutoML. All you need is to write a few lines of code in R or Python.

Auto-ViML

It is another low-code library know as “Auto_ViML” or “Automatic Variant Interpretable Machine Learning” (pronounced “Auto_Vimal”) developed to serve as an AutoML pipeline that could effectively contribute to modern data workflows. It accepts any dataset that is in the form of Pandas Dataframe. It performs data cleaning and category feature transformation like identifying missing values and left to the model to decide how to use them. It also performs feature selection automatically to produce the simplest model with the least number of features and high performance.

It provides a verbose output that allows for a great deal of understanding and model interpretability. Install Auto_ViML through ‘pip install autoviml’. It produces model performance results as graphs automatically. It can handle text, date-time, numeric, boolean, factor, and categorical variables all in one model. Users can use the featuretools library to perform Feature Engineering.

 

Features of the latest version are

  • Use SMOTE for the imbalanced dataset and set Imabalanced_Flag = True in the input.
  • It detects text variables automatically and does NLP processing on those data.
  • It also detects data time variables automatically and adds extra features.
  • Now users can perform feature engineering with the available featuretools library.

To get more information about Auto-ViML. To get the more stable and full version using this command pip install git+https://github.com/AutoViML/Auto_ViML.git

No Code ML Platforms

CreateML

Create ML is a no-code drag and drop tool developed by Apple for mac users. It is an independent macOS application with a bunch of pre-trained model templates. Build your custom models with the help of transfer learning. It has a variety of model types such as Image Classification, Style Transfer, Sound Classification, Text Classification, and Recommendation system where you can select the model type and add data, parameters to start training.

Before the training, you can set the iteration count and fine-tune the metrics. For models like style transfer, it provides real-time results on validation data. At last, it generates a CoreML model, which you can test and deploy in IOS applications.
