## Preditions format

The acceleration data have been recorded at a 50 Hz frequency (i.e. 50 values per second) but the prediction frequency has to be reduced to 1 Hz (i.e. 1 value per second). Once you have predicted the 6th day of activity journal, you have to reshape your predictions into a *second*-granularity matrix containing 2 columns: the times (e.g. '11:12:12') and the activity ("none", "A", "N", ...).
