AI Chatbot Glossary
What Is Machine Learning?
Machine learning is a branch of AI where systems learn and improve from data without being explicitly programmed — the basis for modern chatbot language understanding.
Definition
A branch of AI where systems learn and improve from experience without being explicitly programmed. Machine learning algorithms analyze patterns in data to make predictions, classify information, and improve chatbot responses over time based on real interactions.
Why Machine Learning Matters for AI Chatbots
Machine learning is the foundation underneath AI chatbots, but you do not interact with it directly when deploying a bot. You pick a model (trained with ML), give it content (via RAG) and instructions (via prompts), and let it go. ML work is the vendors' job.

Deep Learning
Deep learning is a subset of machine learning using neural networks with many layers to learn complex patterns from large data sets.
Large Language Model (LLM)
An LLM is an AI model trained on vast amounts of text that can understand and generate human language — LLMs like GPT-5.4, Claude, and Gemini power modern chatbots.
Natural Language Processing (NLP)
NLP is a field of AI focused on enabling computers to understand, interpret, and generate human language — powering chatbot capabilities like intent recognition and entity extraction.
