Contrastive Geometric Transfer: Efficient Sentence Embeddings via Hyperbolic Projection with 24× Compression

2026 · Zenodo (CERN European Organization for Nuclear Research)

Experimental results for Contrastive Geometric Transfer (CGT), a method for compressing sentence embeddings via hyperbolic projection. Achieves 24× compression (768d→32d) with 97.4% quality retention (Spearman ρ=0.812 vs baseline 0.834). Outperforms PCA by 5.9% at 32d …
