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