Neural networks are changing the world around us?from voice assistants on our phones to medical diagnosis and self-driving cars. But learning about them can feel overwhelming. This book makes neural networks simple and accessible for everyone. The book takes you on a clear journey from the basics to modern AI systems. It starts by showing how artificial neurons were inspired by the human brain, then builds up step by step to today's powerful architectures like transformers and generative models. The book is organized in five clear parts: building blocks, core architectures for different data types, modern language processing techniques, generative models, and practical applications. Each part builds naturally on the previous one.
