PAMAP2 dataset preprocessed v0.1.0

 Processed PAMAP2 dataset
This dataset is based on the [PAMAP2 Dataset for Physical Activity Monitoring](https://archive.ics.uci.edu/ml/datasets/PAMAP2+Physical+Activity+Monitoring).

The data is processed with the code in the [mcfly repository]

(https://github.com/NLeSC/mcfly/blob/master/tutorial/tutorial_pamap2.py).

The preprocessing is similar to that in the paper of Reiss and Stricker, 2012. Windows of length 512 were extracted from within the activity period.

Only the variables from the 16g accelerometers on hand, ankle and chest are selected.

Only the activities that were performed by all subjects were selected.
