Qwen2.5 7B for Bengali: Chat Vector
This model is built on top of Qwen2.5 7B adapted for Bengali using 500M target language tokens sampled from MADLAD-400. It has an additional target vocabulary of 10K. Chat vector was added to the model after continual pre-training.
Model Details
- Vocabulary: This model has an additional target vocabulary of 10K.
- Target vocabulary initialization: The target weights of the embedding and LM head were initialized using mean initialization.
- Training: This model was continually pre-trained on 500M target language tokens sampled from MADLAD-400.
- Post-processing: The model was post-processed using the Chat Vector method.
