BDH Continual-Learning Phase-1 Checkpoints (RA2b)
40 PyTorch checkpoints of the RA2b route-aware growth ladder: a 20-phase continual-learning run over 20 European languages (europarl corpora), one language per phase, route-aware auxiliary loss (alpha 0.9), append-only growth (+32 mult per phase) with step-end frozen-region restore. For each language both the best-val and the last checkpoint are provided.
Contents
- checkpoints/ — bdh_europarl_ladRA2b-_best.pt and _last.pt, languages: bg cs da de el en es et fi fr hu it lt nl pl pt ro sk sl sv
- metadata/ra2b_acquisition.{csv,json} — phase schedule: mult range, tokens, parameters, bytes per phase
Loading
These are pipeline-native PyTorch .pt files, not safetensors, and not loadable via transformers AutoModel. The model architecture and loading code live in the bdh-cl repository (pipeline/, bdh.py). Expect to instantiate the model from that source code and load the state dict directly.
Provenance
Produced by the Saga AI Labs BDH continual-learning research line (phase 1: RA2b decay/interference closure, final report and 20x20 serving matrix). Checkpoint family: bdh_europarl_ladRA2b-*. License: Pathway MIT (see LICENSE of the source repository). No claims about downstream performance are made beyond the published phase-1 measurements.
