Classification of Intra-Week and Intra-Day Walking Patterns and Their Effect on Body-Composition Changes Using A Hierarchical Model

扫码查看
In this study, we extract intra-week and intra-day activity patterns based on hourly step-count data recorded using an activity meter. The step-count measured each hour over the week is considered to be a bag of words and is applied to a hierarchical topic model with intra-day activity patterns as sub-topics and intra-week activity patterns as super-topics. Using the extracted patterns, we then analyze the dynamic relations between intra-week activities and body weight changes.
