Artificial Intelligence Learning Semantics via External Resources for Classifying Diagnosis Codes in Discharge Notes

Artificial Intelligence Learning Semantics via External Resources for Classifying Diagnosis Codes in Discharge Notes

The settings used for the training model were as follows: (1) minibatch gradient descent with 1000 bench size for optimization; (2) learning rate=.05; (3) momentum coefficient=.9; (4) L2 regularization coefficient=.00001; and (5) tolerance of early stopping per 100 iterations=.0001. Multimedia Appendix 1 shows an example code for implementing the word embedding and CNNs for free-text discharge note classification. Model architecture with 5 convolution channels and 1 full connection (FC) layer.
