codeBert dense retriever

This is a sentence-transformers model finetuned from shubharuidas/codebert-embed-base-dense-retriever. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.
