Awesome job!

A couple questions:

- How was the training/testing data split? Was it split window-wise or participant-wise?

- How does the system perform at elevated heart rates? Seems like it was mostly tested at resting/normal heart rates

1. in this iteration we used a 64% training 16% validation 20% testing split. In our current work we are testing with 10 fold / leave a subject out to get better analysis. 2. the esp dataset had heart rate up to 130 which is relatively high, and the raspberry pi data had people running in place etc... where the heart rate is higher
