Research on geometry edits that make embeddings produce more human-like groupings.

EmbeddingsClusteringEvaluation

Created labeled dataset + splits and compared MiniLM vs MPNet.
Tested projection, prototype, and contrastive steering methods.
Evaluated with ARI and accuracy, analyzing difficulty-based failures.

Fun

Denish — Constructed Language (MIT 24.917)

Designed a complete constructed language with custom phonology, agglutinative morphology, and a bespoke writing system.

LinguisticsConlangWriting System

Built a base-7 number system and strict SVO word order with postpositions.
