Neural Networks

A clear, illustrated guide to large language models, covering key concepts and practical applications. Ideal for projects, interviews, or personal learning.

Master language models through mathematics, illustrations, and code―and build your own from scratch!

It's never been easier to build an AI agent — and never been harder to make one that actually works. This book takes you from language model foundations to production-ready multi-agent systems with the depth to predict failure before it happens, engineer graceful degradation over catastrophic failure, and take absolute architectural ownership.

What really happens inside a neural network? This book explores the tools and ideas researchers use to uncover how AI systems work, from foundational concepts to practical experiments. Learn to separate solid findings from bold claims, develop useful research skills and prepare for a field that is changing as quickly as the technology itself.

Revised for PyTorch 2.x! In 2019, I published a PyTorch tutorial on Towards Data Science and I was amazed by the reaction from the readers! Their feedback motivated me to write this book to help beginners start their journey into Deep Learning and PyTorch. I hope you enjoy reading this book as much as I enjoy writing it.

Benefits of Studying This Book 1. Deep Conceptual Understanding You will understand why AI algorithms work, not just how to run them. This allows you to innovate, debug, and improve models. 2. Career Advantage Strong mathematical foundations make you stand out in interviews for AI, ML, and DS roles. Many recruiters test candidates on linear algebra and probability skills. 3. Research Readiness Postgraduate students and researchers can directly apply these mathematical tools to design and analyze experiments. 4. Practical AI Skills Python-based implementation examples ensure that you can directly apply mathematical concepts in real-world AI systems. 5. Interdisciplinary Edge Mathematics learned here is not limited to AI — it can be applied in robotics, quantum computing, finance, bioinformatics, and more. How This Book Helps After StudyAfter completing this book, you will be able to:·        Build AI models from scratch, knowing exactly what mathematical operations are happening inside.·        Optimize models for performance using a deep understanding of linear algebra operations.·        Analyze and interpret model predictions probabilistically.·        Handle uncertainty and noise in datasets effectively.·        Implement advanced AI concepts like PCA, SVD, Bayesian inference, and Markov models without relying solely on pre-built libraries.This knowledge will directly help in:·        Academics: Scoring well in AI/ML/DS university courses.·        Industry: Working as an AI engineer, data scientist, ML engineer, or research scientist.·        Competitive Exams: Preparing for GATE, NET, and other AI-related exams where mathematics is heavily tested.·        Research: Publishing papers where mathematical rigor is required to explain new AI techniques. 

Master deep learning with PyTorch & Lightning. Core concepts, practical Q&A, and production-ready code with a full companion GitHub repository.

AI is changing the way we find and fix software vulnerabilities. Intelligent Discovery explores the techniques behind this shift, from static analysis to AI-driven vulnerability research and automated repair. With a clear-eyed look at both the potential and the pitfalls, it shows what these tools can do, where they fall short and why human expertise still matters.

A chatbot can describe how to do your work. An agent can do it—if you build it to be trusted. Learn to construct, verify, and deploy AI agents that earn a place in real scientific and engineering practice.

Stop choosing between an AI that's powerful and one you can certify. From Shannon's entropy to a reproducible, auditable Industry Language Model — built in C#, wrapped in Deterministic Islands, with every number independently verified.

Every news feed is full of AI buzzwords: Transformers, tokens, embeddings, context windows, hallucinations, objective functions. Yet most explanations are either dense academic textbooks or empty marketing fluff. ☕ Coffee Break AI is your practical guide to AI. Written in plain English with warm real-world analogies. It breaks down the core mechanisms of AI into 40 bite-sized chapters.

We'll stick to five libraries, not because more would be a problem, but because keeping it simple shows how well we can organise things. When you download MNIST with just the standard library, you finally see what a dataset loader was hiding. If you write attention as four lines of NumPy before you ever call a PyTorch module, it's no longer a magic process but just plain arithmetic.
