Arrhythmia detection using deep convolutional neural network with long duration ECG signals
Hi tom,I find that you save fragment of hea file as data. But I plot it and find that the wave of hea file looks a little different with wave plotted by physioBank ATM. Is it ok or are they the same thing?
I think he doesn't seem to have trained his characteristics
First of all thanks for doing nice work on slicing MIT-BIH data
I wanted to test the code with the 30s and 60s slices of ecg. I am able to create slices and get aux labels.
But it gives me error. That is obvious because I have different value in df.
target:N, num: 283
len df: 326
target:L, num: 103
len df: 56

If I understand how you decided num_labels_dict
value I can fix it for 30/60s strips. I checked your research paper and codes but did not get any clue.
Really appreciate your reply.
