What is LaBSE?
LaBSE is a powerful multilingual sentence embedding model that represents a significant advancement in cross-lingual natural language processing. Originally developed by Google and ported to PyTorch, it's designed to map sentences from 110 different languages into a shared vector space, enabling robust cross-lingual similarity comparisons and analysis.
Implementation Details
The model is built on a BERT architecture with specific optimizations for multilingual processing. It features a max sequence length of 256 tokens and implements a sophisticated pooling strategy that focuses on CLS token pooling followed by normalization. The model utilizes a dense layer with 768 features and employs tanh activation for optimal performance.
