Gemma2 9B for Sinhala + ElChat

Model Details

• Vocabulary: This model has an additional 100 target vocabulary.
• Target vocabulary initialization: The target weights of the embedding were initialized using Align.
• Training: This model was additionally pre-trained on 30K target language sentences sampled from CC-100. The training was conducted with the 2x2LS/MTP/512 strategies introduced in the paper.
• Post-hoc adaptation: This model used ElChat, a training-free, post-hoc method. See https://arxiv.org/abs/2412.11704 for details.
