Fine-tuning
Taking a ready-made AI model and giving it extra training on specific material so it gets good at one particular job.
Think of it as: A qualified doctor who goes on to specialise in hearts.
More words in How it works
- GANGenerative adversarial network. An older way of making fake images, where one network creates and another tries to catch it out, so both improve.
- GPTGenerative pre-trained transformer. The type of model behind ChatGPT: it generates text, was trained in advance on lots of writing, and uses the transformer design.
- Gradient descentThe method a model uses to improve during training: take a small step in whichever direction reduces its errors, and repeat millions of times.
- Ground truthThe known correct answer that an AI's output is checked against.
- HandoffWhen one AI agent passes a task, and everything it knows about it, to another agent better suited to continue.
