The Mathematical Methods of Artificial Intelligence: Purpose, Role, and Real-World Application - Tapa blanda

Sinopsis

The Mathematical Methods of Artificial Intelligence Purpose, Role, and Real-World Application Beneath every chatbot, recommendation engine, and image classifier lies not a single mysterious algorithm — but a small, precise set of mathematical methods, each doing a specific job. This book names them, explains them, and shows exactly where they work inside systems you use every day. "The mystery, on inspection, resolves into a toolkit — and this book is a guide to the tools." Twelve chapters, one method each. Linear algebra encodes a Netflix film as a vector of hidden tastes. Calculus finds the direction of improvement inside a training loop. Gradient descent walks that direction, step by step, until a language model learns to predict language as people actually write it. Probability turns uncertain evidence into a Gmail spam decision. Information theory supplies the very measure of error that trains ChatGPT. And logic — the oldest method of all — still guarantees, with mathematical certainty, that aircraft software will never fail in a way no test ever caught. Every chapter follows the same structure: definition · purpose · role in AI · key formulas · one real system. Read in sequence, the chapters build from foundation upward. Read singly, each stands as a self-contained reference. No advanced background is assumed beyond basic algebra and a willingness to read an equation as a compact sentence. Inside this book: Linear algebra → Netflix recommendations · Calculus → Image classifier training · Gradient descent → GPT-family LLMs · Probability → Gmail spam filter · Statistics → A/B testing at scale · Information theory → ChatGPT word prediction · Regression → Credit scoring (FICO) · Distance & similarity → Spotify playlists · Neural networks → Voice assistants (Siri) · Dimensionality reduction → Eigenfaces & face ID · Graph theory → Google PageRank · Logic & symbols → Formal verification.
