How to Learn AI Skills for Free – The Roadmap
Step 1 – Build Strong Foundations in Math & Programming
AI relies heavily on math and coding. Start with:
- Basic Math: Linear algebra, statistics, and probability. (Free resources: Khan Academy)
- Programming: Python is the most beginner-friendly language.
- Python.org offers free official documentation.
- FreeCodeCamp’s Python for Beginners is a great starting point.
Step 2 – Learn Core AI & Machine Learning Concepts
Understand the building blocks of AI:
- Machine Learning (ML) algorithms (supervised, unsupervised, reinforcement learning)
- Neural networks & deep learning basics
- Natural Language Processing (NLP) for text-based AI
Free resources:
- Google’s Machine Learning Crash Course
- Coursera’s AI for Everyone (audit for free)
Step 3 – Practice with Free AI Tools & Datasets
Learning by doing is key.
- Use platforms like Kaggle for datasets and competitions
- Experiment with Google Colab for free cloud-based coding
- Explore open-source projects on GitHub
Comparison Table Example:
| Resource | Type | Cost | Best For |
|---|---|---|---|
| Kaggle | Practice | Free | Datasets, Competitions |
| Google Colab | Coding | Free | Building ML Models |
| GitHub | Projects | Free | Open-source Collaboration |
Step 4 – Join AI Communities & Learn from Experts
Networking accelerates learning. Join:
- Reddit’s r/MachineLearning
- AI-related Discord groups
- Local AI meetups (search on Meetup.com)
