Last Updated on August 28, 2020 Indoor movement prediction involves using wireless sensor strength data to predict the location and motion of subjects within a building. It is a challenging problem as there is no direct analytical model to translate the variable length traces of signal strength data from multiple sensors into user behavior. The ‘indoor user movement‘ dataset is a standard and freely available time series classification problem. In this tutorial, you will discover the indoor movement prediction time […]

Last Updated on August 5, 2019 Human activity recognition is the problem of classifying sequences of accelerometer data recorded by specialized harnesses or smart phones into known well-defined movements. It is a challenging problem given the large number of observations produced each second, the temporal nature of the observations, and the lack of a clear way to relate accelerometer data to known movements. Classical approaches to the problem involve hand crafting features from the time series data based on fixed-size […]
