Model Card

mmBERT-base-msa-16384

This model is a 59.96% smaller version of jhu-clsp/mmBERT-base optimized for Malay language via vocabulary size reduction using the trimming method. This trimmed model should perform similarly to the original model with only 16,384 tokens and a much smaller memory footprint. However, it may not perform well for other languages as tokens not commonly used in the selected languages were removed from the vocabulary.
