Electronic device and method for screening features for predicting physiological state

The invention provides an electronic device and a method for screening features for predicting a physiological state. The method includes: obtaining a plurality of physiological data corresponding to a plurality of features; generating a plurality of first subsets of the plurality of features according to the plurality of physiological data based on a first model, wherein the plurality of first subsets respectively correspond to the plurality of physiological data; selecting a first feature from the plurality of features according to the plurality of first subsets, calculating a first relationship index corresponding to a second feature in the plurality of features and the first feature, and selecting the second feature as a companion feature of the first feature according to the first relationship index; and outputting the first feature and the companion feature. 本发明提供一种筛选用于预测生理状态的特征的电子装置和方法。方法包含：取得对应于多个特征的多个生理数据；基于第一模型而根据多个生理数据产生多个特征的多个第一子集合，其中多个第一子集合分别对应于多个生理数据；根据多个第一子集合以从多个特征中选出第一特征，计算对应于多个特征中的第二特征与第一特征的第
