TEmA-small

This model is a fine-tuned version of the LaBSE, which is specialized for sentence similarity tasks in Azerbaijan texts. It maps sentences and paragraphs to a 768-dimensional dense vector space, useful for tasks like clustering, semantic search, and more.

Usage

# Mean Pooling - Take attention mask into account for correct averaging
def mean_pooling(model_output, attention_mask):
