Cuadernos de IA para gente curiosa

Hands-on notebooks from the «Inteligencia artificial para gente curiosa» facsimile, organized by installment and runnable on Google Colab. Each notebook explains one concept step by step with code and real outputs: a hand-built neural network with NumPy, overfitting live, classic ML, BFS/DFS/A*, Sudoku as a CSP, planning (blocks world), minimax/alpha-beta, Q/K/V attention by hand, temperature/top-k/top-p, quantization, a mini-GPT from scratch, tokens and cost, structured outputs and a minimal ReAct agent.
