Probabilistic Ensemble Framework for Injury Narrative Classification
Autor: Srushti Vichare, Gaurav Nanda, Raji Sundararajan
Publikováno v: AI, Vol 5, Iss 3, Pp 1684-1694 (2024)
In this research, we analyzed narratives from the National Electronic Injury Surveillance System (NEISS) dataset to predict the top two injury codes using a comparative study of ensemble machine learning (ML) models. Four ensemble models were evaluat
