Doctor AI— Computational Phenotyping from Electronic Health Records 

Abstract

Can Artificial Intelligence (AI) help improve healthcare? The central task for AI in medicine is to develop efficient and accurate phenotyping methods that can transform large volume of complex and noisy electronic health records (EHR) into meaningful clinical patterns (or phenotypes). We will describe several promising phenotyping techniques to support various healthcare applications such as disease risk prediction, treatment recommendation and phenotype discovery:

  1. Deep learning: We present a series of neural network methods that can handle temporal patterns, leverage existing medical knowledge, exploit complex relationships within EHR data.
  2. Tensor factorization: We introduce a set of tensor factorization methods that are designed to model large volume of unlabeled and time-evolving EHR data to extract novel phenotypes.
