Applying convolutional nets to one dimensional time series data is a fairly common problem in medicine, and the techniques here can certainly transfer to other medical domains. Besides the plethora of opportunities in one dimensional signals (ECG, PCG, PPG, EEG, etc), many medical problems pose similar challenges to machine learning techniques. For example:<p>* Massive class imbalance -- we have much more data for healthy patients than for sick patients, especially at the scales required for deep learning.<p>* Heavy amounts of noise -- Medical imaging is a difficult feat and noise is a fact of life. Not only that, but data is hard to come by and some noise in the labels is likely.<p>* Long term outcomes -- trying to predict diseases or other long term results from signals is very difficult, especially when the outcome is not immediately obvious by looking at the input.<p>TLDR: Imagine that you have to compete in ImageNet, but the images are full of noise, half of the ones labeled "dog" are actually some sort of bird, and instead of guessing what's in the image, you're given an image and then asked to guess if that image, when painted in watercolor, will make a baby smile.

I know I may be asking to go down a rabbit hole, but:<p>(1) Does the NN use a deep architecture?<p>(2) How does the CNN performance compare with other algorithms?<p>(3) Have you looked at how performance varies with different features, frequency cut-offs, etc.?

This is a great idea. Well done!<p>Can't wait we figure out a way to collect these kind of signals in a scalable way.<p>Technology is great, but data is king.

I hate to be a jerk, but... what is the point of this entire competition? Physionet audio recordings of heart murmurs? Stethoscopes are on their way out.<p>Cool model, I guess. Does it get us anywhere new? I don't know.
