Question
A hospital data analyst is tasked with building a model
to predict patient readmission rates based on historical data. Which method should the analyst prioritize for effective prediction?Solution
Random Forest is well-suited for predictive tasks in healthcare, such as predicting readmission rates, as it is an ensemble method combining multiple decision trees to increase accuracy and reduce overfitting. In healthcare, where data is often complex and involves various risk factors, Random Forest can handle this complexity by aggregating multiple decision tree results, thereby improving prediction accuracy. The algorithm is robust to noise and outliers, common in healthcare datasets, and offers insights into variable importance, helping analysts identify critical readmission factors. Thus, Random Forest provides a reliable predictive framework, balancing interpretability and precision. The other options are incorrect because: • Support Vector Machines (SVM) require carefully tuned parameters and are less interpretable for complex healthcare data. • Decision Trees are interpretable but prone to overfitting, which can compromise prediction quality. • Neural Networks are powerful but require large datasets and computational power, making them less practical. • Principal Component Analysis (PCA) is a dimensionality reduction technique, not a predictive model.
