Chapter 1: AI & ML Unplugged: What’s the Big Idea?

Welcome, future innovator! Are you curious about Artificial Intelligence (AI) and Machine Learning (ML), but feel like it’s all complex jargon and advanced math? You’re in the right place! This guide is designed for you – someone with zero prior coding experience, ready to explore these fascinating fields one gentle step at a time.

In this first chapter, we’re going to “unplug” AI and ML, stripping away the hype and diving into the core ideas. We’ll build an intuitive understanding of what AI and ML actually are, why they’re so powerful, and how they essentially “learn” from data. Think of it as laying the foundational bricks before we even think about mixing the cement. By the end, you’ll have a clear conceptual map of these technologies, understand their real-world impact as of 2026, and even start thinking about the ethical considerations they bring. No coding required in this chapter – just pure, curious exploration!

Chapter 14: Project 2: Aligning an LLM for Factual Accuracy

Fri, 30 Jan 2026 00:00:00 +0000

Introduction: Guiding LLMs Towards Truth

Welcome back, future LLM alignment expert! In our previous project, we explored fine-tuning an LLM for a specific style. Now, we’re tackling an even more critical challenge: factual accuracy. Large Language Models, despite their incredible capabilities, are notorious for “hallucinating” – generating plausible-sounding but incorrect information. This can severely limit their trustworthiness and utility in many real-world applications.

In this chapter, we’ll embark on a practical project using Tunix to align an LLM to be more factually accurate. We’ll learn how to leverage Tunix’s powerful post-training framework to reduce hallucinations and ensure our models provide reliable information. This project will reinforce your understanding of data preparation, reward modeling, and iterative alignment techniques.
