Multi-layer Representation Learning for Medical Concepts

Understand

Learning efficient representations for concepts has been proven to be an important basis for many applications such as machine translation or document classification.

• Proper representations of medical concepts such as diagnosis, medication, procedure codes and visits will have broad applications in healthcare analytics.
• However, in Electronic Health Records (EHR) the visit sequences of patients include multiple concepts (diagnosis, procedure, and medication codes) per visit.
• This structure provides two types of relational information, namely sequential order of visits and co-occurrence of the codes within each visit.
