Artificial Intelligence

From Fundamentals to Advanced Research

This hub is the front door to every AI topic on the site. It connects four depths of theory — from a plain-English intro to graduate-level proofs — with the hands-on generative-AI guides:

  • Four depth levels. Simplified → Complete → Deep Dive → Mathematics. Climb only as far as you need.
  • Theory meets practice. Every concept links to a hands-on generative-AI guide you can run today.
  • Current research. Foundation models, multimodal systems, and alignment — the 2025–2026 frontier.

How These Pages Fit Together

This hub points to four depth levels of AI theory plus the hands-on generative-AI guides. Pick a depth, then branch into practice:

Core AI Domains

AI is not one field but several overlapping ones, each defined by the kind of data it works with and the structure it exploits. The table below is a quick orientation; the sections that follow go into each domain and link to the relevant guides.

Domain What it does Defining method On this site
Machine Learning Learn patterns from data to predict or decide Statistical models, gradient descent AI Fundamentals
Deep Learning Learn hierarchical features from raw input Multi-layer neural networks AI Deep Dive
Natural Language Processing Understand and generate human language Transformers, large language models AI Deep Dive
Computer Vision Interpret and generate visual information CNNs, diffusion models Stable Diffusion
Generative AI Create new images, text, audio, and video Diffusion, GANs, autoregressive LLMs ComfyUI Guide

Deep learning is a subset of machine learning; NLP, computer vision, and most of generative AI are in turn powered by deep learning today. Understanding that nesting is the fastest way to navigate the field.
