Explore the fine-tuning process of sentence transformers using Natural Language Inference (NLI) softmax loss in this comprehensive video tutorial. Learn about the training approach used in the first sentence-BERT (SBERT) model for producing sentence embeddings. Dive into the preprocessing of NLI data, implement the PyTorch process, and utilize the Sentence-Transformers library. Examine the results and understand why this method, while historically significant, has been superseded by more advanced techniques. Gain insights into applications such as semantic textual similarity, clustering, and information retrieval using concept-based embeddings.
