Automatic Feature Extraction on PAMAP2 Dataset using CNN+LSTM

I am processing the PAMAP2 dataset, and I have segmented using a 5.12 seconds sliding window. I have also extracted the features using mean, median and std. However, I want to extract the features automatically using CNN+LSTM. Please check out the PAMAP2 dataset to understand better. http://archive.ics.uci.edu/ml/datasets/pamap2+physical+activity+monitoring
