Advanced Topic 39 of 51 AI & Machine Learning

Embeddings

Dense vectors capturing meaning of items.

How it works

Embeddings map words, images or items to dense vectors where similarity reflects meaning (cosine distance), learned by models like word2vec or transformers.

Where it is used

Semantic search, recommendations.

Common pitfall

Embeddings inherit bias in training data.

Where it fits in the course

Embeddings is topic 39 of 51 in AI & Machine Learning, rated Advanced. It follows Large Language Models. The next topic is Transfer Learning.
