Investigating Inter-Subject and Inter-Activity Variations in Activity Recognition Using Wearable Motion Sensors.
The Computer Journal(2016)
摘要
This work investigates inter-subject and inter-activity variability of a given activity dataset and provides some new definitions to quantify such variability. The definitions are sufficiently general and can be applied to a broad class of datasets that involve time sequences or features acquired using wearable sensors. The study is motivated by contradictory statements in the literature on the ne...
