Bug in EMG Example

[krabo0om]

torchhd/examples/emg_hand_gestures.py

Line 42 in 6b69e36

samples = torchhd.bind(signal, self.timestamps.weight.unsqueeze(1))

Should be samples instead:

samples = torchhd.bind(samples, self.timestamps.weight.unsqueeze(1))

Thank you for reporting this bug! With the fix the accuracy is also improved, from:

List of subjects [0]
Testing accuracy of 94.937%
List of subjects [1]
Testing accuracy of 93.919%
List of subjects [2]
Testing accuracy of 86.897%
List of subjects [3]
Testing accuracy of 93.007%
List of subjects [4]
Testing accuracy of 76.238%

Which is now:

List of subjects [0]
Testing accuracy of 98.734%
List of subjects [1]
Testing accuracy of 96.622%
List of subjects [2]
Testing accuracy of 99.310%
List of subjects [3]
Testing accuracy of 97.902%
List of subjects [4]
Testing accuracy of 97.030%

I will go ahead and make a PR and a new release of the library.
