Embedding

Sketch: the word dog becomes a list of numbers; then on a map, dog and puppy sit close and invoice sits far away.

An embedding is a list of numbers that captures the meaning of text or an image, so similar things end up close together.

Think of it like this: Think of map coordinates for meaning: ‘puppy’ and ‘dog’ get parked on the same street, ‘invoice’ far away. Search and memory tools use these coordinates to find related things.
