Understanding Sentence Transformers

What are Sentence Transformers?

Definition and Basic Concepts

Sentence transformers have fundamentally transformed the landscape of natural language processing (NLP). These models, including notable examples like BERT, RoBERTa, and DistilBERT, are designed to convert sentences into fixed-dimensional vectors known as embeddings. By capturing the semantic essence of entire sentences rather than individual words, sentence transformers enable more nuanced and context-aware representations of textual data.

The core concept behind sentence transformers is their ability to generate dense vector representations that encapsulate the meaning of sentences, paragraphs, or even larger text blocks. This capability stems from the underlying architecture of transformer networks, which leverage self-attention mechanisms to weigh the importance of different words in a sentence relative to each other. This results in embeddings that are rich in semantic information and highly effective for various downstream NLP tasks.
