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-sized […]
