you work with Artificial Intelligence development, if you are studying, or planning to work with that technology, you certainly stumbled upon embedding models along your journey.
At its heart, an embedding model is a neural network trained to map like words or sentences into a continuous vector space, with the goal of approximating mathematically those objects that are contextually or conceptually similar.
Putting it in simpler words, imagine a library where the books are not categorized only by author and title, but by many other dimensions, such as vibe, topic, mood, writing style, etc.
Another good analogy is a map itself. Think of a map and two cities you don’t know. Let’s say you are not that good with Geography and don’t know where Tokyo and New York City are in the map. If I tell you that we should have breakfast in NYC and lunch in Tokyo, you could say: “Let’s do it”.
However, once I give you the coordinates for you to check the cities on the map, you will see they are very far away from each other. That is like giving the embeddings to a model: they are the coordinates!
Building the Map
Even before you ever ask a question, the embedding model was trained. It has read millions of sentences and noted patterns. For example, it sees that “cat” and “kitten” often appear in the same kinds of sentences, while “cat” and “refrigerator” rarely do.
With those patterns, the model assigns every word a set of coordinates on a mathematical space, like an invisible map.
- Concepts that are similar (like “cat” and “kitten”) get placed right next to each other on the map.
- Concepts that are somewhat related (like “cat” and “dog”) are placed near each other, but not right on top of one another.
- Concepts that are totally unrelated (like “cat” and “quantum physics”) are placed in completely different corners of the map, like NYC and Tokyo.
The Digital Fingerprint
Nice. Now we know how…
