What you'll learn

We are going to guide you through the knowledge which is necessary for every data scientist. We will show you the world of classic machine learning with models like linear and logistic regression, decision trees, model compositions, and much more, while also familiarizing you with more modern methods based on neural networks. Additionally, you will work with SQL, which is one of the core skills for any aspiring data scientist.

Upon completion of this track, you will:

  • Get acquainted with basic linear models and their extensions while learning the necessary math to understand how these work;
  • Learn more complex concepts like decision trees and compositions such as random forests and gradient boosting;
  • Discover many different tasks a data scientist might face, including the most common ones like classification and regression, alongside clustering and dimensionality reduction;
  • Study a variety of neural networks: different architectures, optimizers, and much more;
  • Gain experience with convolutional neural networks for computer vision tasks and recurrent neural networks for sequence data;
  • Strengthen your data manipulation skills with advanced SQL queries;
  • Get a solid foundation for your own experiments in the field by solving various tasks and projects.

Learn by doing

# 1
Apply knowledge into practice
You already know the theory. Now it's time to code like you do at work—in a professional IDE, with real project constraints, solving problems that actually matter. Welcome to software engineering as it should be.
# 2
Navigate complexity with surgical precision
Most developers waste months learning random concepts without seeing how they connect. Our interactive Knowledge Map fixes this. It shows exactly how every programming concept relates to others, helping you build a structured mental model of coding.
# 3
Copy the best. Then improve.
Here's what top engineers do that others don't: they study other people's code obsessively. When you get stuck on Hyperskill, you can explore solutions published by other developers. See their exact code. Understand their approach. Learn their tricks.
# 4
Code review that actually makes you better
We stripped code review down to what actually matters: does your solution work? Have you handled the edge cases? Is there a cleaner way to write this? Hyperskill acts like a competent reviewer who actually tests your code. Not genius-level analysis, not architecture debates — just solid feedback on making your code better.

Elevate your engineering mastery through real-world challenges

Master advanced engineering concepts through ambitious projects. Each project deepens your expertise and transforms you from an experienced engineer into an exceptional one.

Predictive Analysis and Optimization with Boosting Algorithms

This project uses boosting algorithms to develop and optimize predictive models for medical insurance costs. It encompasses data analysis and feature transformation and provides a basic overview of boosting algorithms. It will guide and support you in implementing and optimizing these algorithms to achieve accurate predictive analytics.
