Getting more out of LSTMs for classifying multimodal health data

Overview

Background

Our data

We used emergency department (ED) visit record data to develop our models. The records had one free-text field, chief complaint, along with a number of other discrete variables, like age group, sex, mode of arrival, and hospital code. This is the third project we've done with the data, so if you're interested in learning more about them, check out our papers about using them for classifying chief complaints and for generating synthetic chief complaints.

Our results

Code

Example preprocessing run:

python preprocessing.py ^
--data_dir=C:/data/syndromic/ ^
--input_file=sample.csv ^
--file_type=csv ^
--text_column=cc ^
--clean_text=True ^
--convert_numerals=True ^ 
--target_column=ccs

And an example training and test run:

python train_and_test.py ^
--data_dir=C:/data/syndromic/ ^ 
--text_file=word_sents.hdf5 ^
--records_npz=sparse_records.npz ^ 
--records_csv=sample.csv ^
--target_column=ccs ^
--patience=1
