We explore the efficacy of modern machine learning methods for the task of modeling sepsis progression.We applied a novel imputation and feature selection scheme based on signal processing technology and our medical expertise.We compared the performance of several approaches including neural networks, sparse quantile regression, and baseline classification algorithms such as random forest and SVMs.Among all the experimented methods, CNN-LSTM neural network performed the best with the full test utility score of the challenge being 0.076.We conclude that the application of neural network, random forest, sparse quantile regression, neighborhood algorithms, and naive Bayes classifiers yields superior performance with respect to accuracy, sensitivity, and specificity.[Team: Sepsis ReSepsion]
