LLM word embeddings form circular patterns in a high-dimensional analysis

jamiesimon.io 3 min read Editor score 7/10

The analysis finds that month embeddings project to a circle and have an approximately circulant Gram matrix, with similar patterns in word2vec. Engineers working with embeddings can use these geometric results to inform how they interpret representation spaces.

What
An analysis examines the geometry of word embeddings, including whether selected word vectors form circles in a PCA projection.
How
An iterative search found word2vec sets matching a target circulant Gram matrix and forming clear circles; embedding size did not enter the search.
Why it matters
Embedding plots can be shaped by how vectors are selected, so engineers should be cautious when interpreting geometric patterns as inherent structure.
