Machine learning models improve Japanese election forecasting

Researchers have developed new nonlinear machine-learning models, utilizing decision tree and ensemble learning techniques, to forecast Japanese lower-house elections. These models showed improved predictive accuracy over a traditional statistical model in both in-sample and out-of-sample tests. This work represents an early application of nonlinear machine learning to single-country election forecasting and suggests a promising alternative to classical linear methods for electoral dynamics.
