Sentence Entity Resolver for ICD10-CM (sbiobert_base_cased_mli embeddings)

Description

This model maps extracted medical entities to ICD10-CM codes using sbiobert_base_cased_mli Sentence Bert Embeddings, and has faster load time, with a speedup of about 6X when compared to previous versions. Also the load process now is more memory friendly meaning that the maximum memory required during load time is smaller, reducing the chances of OOM exceptions, and thus relaxing hardware requirements.

Predicted Entities

Predicts ICD10-CM Codes and their normalized definitions.
