Hi,where are the data_combined of the line of FeatureExtraction2?

jindongwang commented 7 years ago

Hi there, thank you for pointing it out! That's my mistake. I've already changed it in the latest commit. Actually the data_combined in my code refers to combining 3 axis of the accelerometer data together using square root like a=sqrt(ax^2+ay^2+az^2). When you are using this code, you can pass any data (vector of a fixed window perhaps) to the function.
