normalizing raw data in the App

[TZebin]

private void normalize()
{
float x_m = 0.662868f; float y_m = 7.255639f; float z_m = 0.411062f;
float x_s = 6.849058f; float y_s = 6.746204f; float z_s = 4.754109f;

Just curious, where did these values came from?(Min-Max values from the entire dataset?)

Mean and std. values from the WISDM dataset.

Have you considered loading the raw dataset from a file/res/asset in the app instead of the phone accelerometer to check the model's accuracy? The raw data right now does not seem very responsive to the learned model.

I did not.
