1. Definition

  • AI (Artificial Intelligence) aims to create machines that can perform tasks requiring human-like intelligence.
  • ML (Machine learning) is like teaching computers to spot patterns and make decisions based on data without being explicitly programmed for those tasks.

AI: Includes learning, decision-making, and problem-solving.

ML: Giving computers the ability to learn from examples. Just like how you might learn to recognize a cat by looking at lots.

2. Background skills

Don’t worry, you don’t have to be an expert in these.

Background skills to use AI
  • Calculus: Concepts like derivatives and integrals are foundational.
  • Linear Algebra: Know your way around matrices, vectors, and eigenvalues.

  • Python: Master Python syntax and commonly used libraries.
  • TensorFlow/PyTorch: Pick at least one machine learning framework to learn.
  • Understand basic algorithms and data structures: arrays, linked lists, trees, and graphs.

Don’t be scared, though — you don’t need to know deep math to use AI.

You’ll only need it if you plan on going super deep into building AI tools and whatnot.

3. How to study AI

Educational pathways for AI
  • Utilize online courses, tutorials, and research papers. Coursera, Udacity, and edX are platforms to consider.
  • These are intensive, short-term programs focused on practical skills.
Formal Education
  • Degrees in Computer Science, Data Science or AI provide a structured environment and networking opportunities.
  • Obviously, this will take too long.

That’s why you’re better of with courses.
