Multi-layer Representation Learning for Medical Concepts Multi-layer Representation Learning for Medical Concepts
Paper summary This model called Med2Vec is inspired by Word2Vec. It is Word2Vec for time series patient visits with ICD codes. The model learns embeddings for medical codes as well as the demographics of patients. https://i.imgur.com/Zjj6Xxz.png The context is temporal. For each $x_t$ as input the model predicts $x_{t+1}$ and $x_{t-1}$ or more depending on the temporal window size.
