See the data set description for more information on the dataset.\r\n\r\nAttribute Information:\r\n\r\nRaw files: 18 numeric attributes (double), a timestamp and a class attribute (nominal). \r\nProcessed files: 32 numeric attributes (double) and a class attribute (nominal). \r\nA feature vector with up to 50 numeric attributes can be generated with the two files mentioned above.\r\n\r\nThis is the processed data set with the following feature description:\r\n\r\n   Processed files:\r\n\r\n   1.
