Each sensor contains three features: STB (saturation value), MAX (maximum value), and STB-MAX (hybrid value). STB and MAX features each correspond to one column of data, while STB-MAX feature includes two columns of data corresponding to STB and MAX respectively. All sensor data have been preprocessed and feature-extracted. The first column, "Class", represents the category of the data, and the data in the first column correspond one-to-one with the sensor data.
