Researchers have developed VEXMLM, a new language model designed to improve performance on low-resource African languages, specifically Amharic and Tigrinya, which use the Ge'ez script. This model addresses issues of high out-of-vocabulary rates and subword fragmentation common in multilingual models trained primarily on Latin scripts. VEXMLM utilizes a custom SentencePiece tokenizer and an extended vocabulary, demonstrating significant gains in question answering, named entity recognition, and sentiment analysis tasks across 19 African languages.
