An embedding is a numeric representation designed so useful relationships can be measured in vector space.
Why embeddings are useful
They support similarity operations over representation spaces rather than exact strings.
Similarity is task-dependent
Cosine similarity, inner product, and other measures encode different assumptions that should be tested against the application.
Portfolio connection
The multimodal recommender produces a shared representation from text and image encoders before retrieval.
Operational concern
Changing the embedding model or preprocessing can require index rebuilding because the vector geometry changes.
