As Data Scientists, it’s important to stay up to date with the latest technology as data science is a fast-changing field. That said, there are a few key technologies that every data scientist should know and learn about.

To help you know more about these frameworks, this article will give a brief introduction to them, along with helpful tutorials and articles for each of them.

Let’s dive in!

1. scikit-learn

What started out as a Google Summer of Code is now known as the swiss army knife in the ML world, as it applies to most projects. Based on the survey, it was the top ML framework used, with over 80% of data scientists using it.

scikit-learn can perform all the necessary tasks in ML — classification, regression, clustering, dimensionality reduction, model selection, pre-processing.

10. Caret

The caret package (short for Classification And REgression Training) is a package in R that provides a set of functions that attempt to streamline the process for creating predictive models.

The package contains tools for data splitting, pre-processing, feature selection, model tuning using resampling, and variable importance estimation.

11. PyTorch Lightning

PyTorch Lightning was started by William Falcon while completing his Ph.D. AI research at NYU CILVR and Facebook AI Research, with the vision of making it a foundational part of everyone’s deep learning research code. It essentially provides a high-level interface for PyTorch, a popular deep learning framework.

It is a lightweight and high-performance framework that organizes PyTorch code to decouple the research from the engineering, making deep learning experiments easier to read and reproduce.

It is designed to create scalable deep learning models that can easily run on distributed hardware while keeping the model’s hardware agnostic.
