Literature Summaries
Predicting Opioid Overdose Readmission and Opioid Use Disorder with Machine Learning
Objectives
- Use multiple machine learning models and multiple data types to predict the likelihood of hospital readmission following an opioid overdose and diagnosis of opioid use disorder after being prescribed an opioid
Useful Info
- AUC value is a rate of correct prediction
- Hospital info is meant to be anonymized, patient identifiers must be removed
- T40 codes are used as identifiers of various conditions including Covid and OUD
- Various methods of cleaning and compiling hospital records into more useful data frames
- Various viable machine learning models that could be used on my data
- 10 fold cross-validation methods of machine learning
- SMOTE used for class balancing
- Various limitations of hospital data, the data does not include non-registered opioid use or addiction
- "Black box" structure of machine learning models
- Deep learning models such as RNN GRU and LSTM
- Doctor AI used for EHR(Electronic Health Record) data
Questions
- Why is SMOTE necessary?
- What is "gain"?
- How to fix "data noise"?
