40 AI Terms — Plain-English Guide + Hands-On “How-To”

Audience: teachers, student-learners, community mentors, and beginner builders using Incubator.org.
Use this guide: Every term has a short, human-readable definition plus at least one way to try it yourself using widely-used tools (most are free or have generous tiers). Scan the glossary for fast definitions, then jump to the Try it / Tools snippets to actually do something with each idea. Copy the prompt boxes into your AI tool of choice and adapt them for class, self-study, or a workshop.

Quick Glossary (plain English)

  1. Bias — When an AI prefers or treats some things unfairly because of patterns in its training data.
  2. Label — The “answer” attached to data (e.g., a cat/not-cat tag).
  3. Model — The trained program that makes predictions or generates content.
  4. Training — Teaching a model using examples so it improves.
  5. Chatbot — A program that converses by text or voice.
  6. Dataset — A large, structured collection of examples used for training/evaluation.
  7. Algorithm — A step-by-step method to solve a problem.
  8. Token — A chunk of text (or data unit) used by language models.
  9. Overfitting — When a model memorizes the training set and fails on new data.
  10. AI Agent — Software that can plan and act (often across tools/APIs) toward a goal.
  11. AI Ethics — Principles and practices to make AI fair, safe, and accountable.
  12. Explainability — Ways to understand why a model made a decision.
  13. Inference — Running the trained model to get outputs (predictions/generations).
  14. Turing Test — A thought experiment: can a machine’s responses pass for human?
  15. Prompt — The instruction or input you give an AI system.
  16. Fine-Tuning — Further training a model on your specific data or style.
  17. Generative AI — Models that create text, images, audio, or video.
  18. AI Automation — Using AI to complete multi-step tasks without constant supervision.
  19. Neural Network — A model architecture loosely inspired by brain neurons.
  20. Computer Vision — AI that interprets images or video.
  21. Transfer Learning — Starting from a pretrained model and adapting it to a new task.
  22. Guardrails — Controls to keep outputs safe, on-topic, and policy-compliant.
  23. Open-Source AI — Models/tools whose code/weights are openly shared.
  24. Deep Learning — Neural networks with many layers that learn complex patterns.
  25. Reinforcement Learning — Training by trial, error, and rewards.
  26. Hallucination — When an AI confidently makes up facts.
  27. Zero-Shot Learning — Doing a new task without training examples, guided by the prompt.
  28. Speech Recognition — Turning spoken language into text.
  29. Supervised Learning — Training with labeled examples.
  30. Model Context Protocol (MCP) — A standard for letting models securely use local tools/data.
  31. Machine Learning — Letting computers learn patterns from data.
  32. AI (Artificial Intelligence) — Systems that perform tasks we associate with human intelligence.
  33. Unsupervised Learning — Finding patterns in unlabeled data.
  34. LLM (Large Language Model) — Big text models that read/write code, essays, etc.
  35. ASI (Artificial Superintelligence) — Hypothetical AI vastly beyond human general ability.
  36. GPU (Graphics Processing Unit) — Hardware that speeds up AI training/inference.
