What is MedCPT-Cross-Encoder?
MedCPT-Cross-Encoder is a specialized transformer-based model designed for biomedical information retrieval tasks. Developed by the National Center for Biotechnology Information (NCBI), it leverages contrastive pre-training on large-scale PubMed search logs to enable zero-shot retrieval of medical literature.
Implementation Details
The model utilizes the transformers architecture and is implemented using PyTorch. It specifically focuses on ranking articles based on their relevance to input queries, producing numerical scores where higher values indicate greater relevance. The model supports a maximum sequence length of 512 tokens and can process multiple query-article pairs simultaneously.
