Vector Space

A vector space is the mathematical space in which embeddings live — every token or sentence is a point in d_model-dimensional space, and directions in this space can encode semantic relationships.

Where is it used?

In word2vec's space, `king - man + woman ≈ queen` demonstrates that directions encode gender, royalty, and other concepts; the same geometry underlies LLM hidden states.

How to build it

Load GloVe vectors, compute `word2vec['king'] - word2vec['man'] + word2vec['woman']`, and find the nearest neighbor by cosine similarity to verify analogies emerge in the space.
