Training and Finetuning Sparse Embedding Models with Sentence Transformers

Hugging Face published a tutorial on training and fine-tuning sparse embedding models using the Sentence Transformers library. Sparse embeddings offer an alternative to dense vector representations for retrieval tasks, potentially improving interpretability and efficiency. The post covers the tooling and workflows available in Sentence Transformers for producing sparse encoders suitable for search and RAG pipelines.
