This project focuses on new, modular deep learning models that estimate knee joint moments from inertial measurement units, smartphone cameras, or both.

The data of this project are stored in "all_17_subjects.h5". Each subject's data are in a 3-dimensional matrix. The first dimension is for walking steps. The second dimension is for samples (collected at 100 Hz) from heel-strike - 20 samples to toe-off + 20 samples. Both heel-strike and toe-off are detected using right foot IMU data. The length of the second dimension is 152, which is the length of the longest step. Zeros were appended in the end of shorter steps. The third dimension is for 256 data fields, whose name is stored as an attribute named "columns" in the h5 file. An example Python script is provided for loading the data.
