Create Your New High-Income Skill as a Data Scientist / Analyst.

Welcome to DrLee.Ai!
Hi, I'm Dr. Ernesto Lee, and I'm here to propel developers and students into the future of Data Science and Analytics.

Breaking Down the Complexities of Data Science
Too often, data science is shrouded in academic jargon and complex mathematical theories. That's a barrier for many aspiring developers and students like you, who are eager to apply data science in the real world.

Developers and Students Need Practical Skills
What you really need is a practical, code-centric approach. Less theoretical math and more hands-on projects with working code examples. This is where Data Science Mastery steps in.

About Dr. Lee

These courses were made for you.

Learn Best by Implementing From Scratch

...But Simplified Without the Overwhelming Math

For developers and students, real understanding comes from hands-on implementation.

Analytics and Data science algorithms, however, are often wrapped in ridiculous mathematics, covering probability, statistics, and linear algebra.
You don't have to spend years studying math to grasp these concepts.
You Need Clear, Worked Examples (with real-world data)

Imagine if someone demystified the math and provided clear examples with real data.

 This is exactly what you'll find here: easy-to-follow, practical examples showing the inputs, the process, and the outputs.
Master Analytics and Data Science Algorithms for Everyone
...No Advanced Math Required
...Just a Passion for Data Science and Analytics

Introducing the "Master Data Science Concepts" eBook. This guide is designed to provide an accessible introduction to model learning from data and making predictions, focusing on 10 popular and useful algorithms for predictive modeling.
Each algorithm is broken down into step-by-step projects. You'll learn how to plug in data and interpret the results. These guides are designed to be completed in google colab, an approachable format for everyone from beginners to seasoned developers.
Understanding these algorithms in a spreadsheet means you really grasp the concept. You can then apply this knowledge in any programming language or optimize algorithm performance in practical scenarios.
