If you are a developer who wants to transition into AI or elevate your expertise, this guide is designed for you.


1. Understanding AI & Data Science from a Developer Perspective

What is Artificial Intelligence?

Artificial Intelligence refers to systems that simulate human intelligence. These systems can learn, reason, recognize patterns, understand language, and make decisions.

Key branches include:

  • Machine Learning
  • Deep Learning
  • Natural Language Processing
  • Computer Vision
  • Reinforcement Learning

For developers, AI is about building software that evolves based on data.

What is Data Science?

Data Science is the discipline of extracting knowledge and insights from structured and unstructured data using:
