Artificial intelligence, machine learning, deep learning, model, training, inference: the words that show up first in any AI topic. If AI news feels foreign, start with the beginner terms here. Every other category builds on this one.

Level
AGI

AI that could learn any new task, not just the one it was built for

Basics
Algorithm

A fixed sequence and set of rules for solving a problem

Intro
Artificial Intelligence

Often described as machines making people's judgment calls

Intro
Automation vs AI

The difference between following a fixed rule and judging as you go

Intro
Big Data

Data piled up so high it forces you to change tools

Intro
Chatbot

A program you exchange text or speech with, back and forth

Intro
Classification

Picking one of the bins that were already decided in advance

Intro
Clustering

Grouping similar things together with no labels at all

Basics
Computer Vision

Technology that gets a computer to make sense of photos and video

Intro
Data

The row-by-row record that becomes the raw material AI learns from

Intro
Data Science

Turning scattered data into an answer worth acting on

Intro
Dataset

A bundle of material gathered and organized to teach an AI

Intro
Deep Learning

Machine learning that stacks processing steps many layers deep

Intro
Embedding

Rewriting meaning as a set of numbers that marks a spot

LLM Basics
Feature

One ingredient an AI looks at when it makes a judgment

Intro
Generalization

The ability to keep performing well on data never seen before

Basics
Generative AI

AI that invents a result that never existed before

Generative Intro
GPU

A device that processes the same calculation many times at once

Basics
Inference

The moment a trained model produces an answer for a new input

Intro
Label

The answer paired with data for training, usually attached by a person

Intro
Large Language Model

A language model grown enormous by reading a huge pile of text

LLM Intro
Layer

A basic computing stage of neurons that share the same input

Architecture Intro
Machine Learning

Finding rules from examples instead of writing them by hand

Intro
Model

A block of rules saved as-is, left over once training finishes

Intro
Narrow AI

AI built to do exactly one job well

Intro
Neural Network

Simple calculating units chained together in layers

Intro
Neuron

A tiny computing unit that takes in many values and outputs one

Architecture Intro
NLP

The technology that lets computers handle human language

Intro
Parameter

A tuning dial inside a model whose value training decides

Architecture Intro
Pattern Recognition

Spotting the regularity that keeps repeating

Intro
Prediction

Using what you know to guess at a value you don't

Intro
Recommendation System

A system that picks out what you'll like from your past records

Intro
Regression

Naming a single number somewhere on a continuous scale

Basics
Reinforcement Learning

Learning by trying things and adjusting to the score you get back

Training Intro
Speech Recognition

The technology that transcribes spoken words into text

Intro
Supervised Learning

Learning a rule from examples that already carry the right answer

Training Intro
Token

The bite-size pieces an AI cuts text into before reading it

LLM Intro
Training

The process of nudging dials a little at a time from examples

Intro
Turing Test

A test that guesses human or machine from conversation alone

Intro
Unsupervised Learning

Finding structure in data with no answers attached

Training Intro
Weight

The learned multiplier on each input, deciding how much it counts

Architecture Intro
