## Cat Embeddings

A set of embedding model trained for study embedding quality vs model architecture (width/depth) given a size constraint (12M params).

- **cat-emb-2-128**: 2 layers/hidden size 128/4.4m
- **cat-emb-4-128**: 4 layers/H 128/4.8m
- **cat-emb-8-128**: 8 layers/H 128/5.6m
- **cat-emb-12-128**: 12 layers/H 128/6.4m
- **cat-emb-2-256**: 2 layers/H 256/9.7m
- **cat-emb-4-256**: 4 layers/H 256/11.3m

### Training

- stage 1: seq 192, batch size 2048, 50k steps, sentence pairs.
- stage 2: seq 512, batch size 64, 5k steps, sentence triplets.
