What is nli-mpnet-base-v2?
nli-mpnet-base-v2 is a sophisticated sentence transformer model developed by the sentence-transformers team. It's designed to map sentences and paragraphs into a dense 768-dimensional vector space, making it particularly effective for semantic search, clustering, and similarity tasks.
Implementation Details
The model is built on the MPNet architecture and includes a two-component pipeline: a transformer encoder followed by a pooling layer. It processes input text with a maximum sequence length of 75 tokens and employs mean pooling for generating sentence embeddings.
- Built on MPNet architecture with 109M parameters
