Personalized Step Counting Using Wearable Sensors: A Domain Adapted LSTM Network Approach

no code implementations11 Dec 2020 Arvind Pillai, Halsey Lea, Faisal Khan, Glynn Dennis

In this study, we hypothesize: (1) raw tri-axial sensor data can be modeled to create reliable and accurate step count, and (2) a generalized step count model can then be efficiently adapted to each unique gait pattern using very little new data.
