Method of Evaluating a Data Set with Regard to Suitability for Determining a Calculation Function of a Virtual Sensor

A computer-implemented method of evaluating a data set with respect to suitability for determining a calculation function of a virtual sensor, the method comprising:

• providing the data set, wherein the data set comprises measurement data resulting from a measurement of measured variables by at least two real sensors, wherein the measurement data has a particular dimension for the at least two real sensors;
• providing an input range defined for the measured variables of the at least two real sensors to specify at least one requirement for determining the calculation function;
• determining a coverage ratio between the data set and the provided input range using a machine learning model;
• evaluating the data set based on the determined coverage ratio;
• and
• expanding the data set by further data points to increase the coverage ratio of the data set by the further data points, wherein the further data points lie in a non-covered area of the input range by the data set.
