Text Classification with Large Language Models

In the era of modern artificial intelligence, text classification has evolved far beyond simple keyword matching and manual rule-writing. Utilizing the power of Large Language Models (LLMs) allows you to categorize, tag, and analyze unstructured text with unprecedented accuracy and minimal training data. This text-based course guides you through the foundational concepts and modern workflows needed to implement LLMs for real-world downstream classification tasks. You will transition from understanding core natural language processing principles to designing robust, production-ready classification systems. Along the way, you will explore contemporary engineering practices like structured JSON outputs and prompt engineering patterns that ensure consistent model behavior. What you'll learn: - Understand the core concepts of downstream tasks and how LLMs process text data - Design effective prompt templates specifically optimized for sentiment analysis and multi-class categorization - Implement modern API integration techniques to send text payloads and parse model responses - Apply advanced zero-shot and few-shot learning techniques to classify text without extensive training sets - Structure LLM outputs into reliable formats like JSON to feed directly into downstream software systems - Evaluate classification performance using standard metrics to ensure high-quality outputs The course starts with essential terminology and the mechanics of text embeddings, gradually building up to hands-on classification workflows and integration strategies. This structured progression ensures you understand both the 'why' and the 'how' of modern NLP pipelines. This course is designed for software developers, data enthusiasts, and product builders who are new to LLM integration. No prior machine learning background is required, though a basic familiarity with programming concepts will help you get the most out of the written examples.
