MFPT Bearing Dataset
--------------------

MFPT datasets were provided by Society for Machinery Failure Prevention Technology [@MFPT]. MFPT datasets consisted of three bearing datasets: 1) a baseline dataset sampled at 97656 Hz for six seconds in each file; 2) seven outer ring fault datasets sampled at 48828 Hz for three
