Method for determining at least one physical value in data and associated products

A method for determining at least one physical value in data, the method being computer-implemented, the method for determining comprising:

• a training phase during which a converting function of a device for determining at least one physical value in data is trained, the device being adapted to apply:
• an estimating function adapted to estimate the at least one physical value based on input data, and
• a conversion function on incoming data to obtain input data for the estimating function,
• the training phase comprising the steps of:
• obtaining a dataset whose elements are incoming data and the corresponding physical value and a set of predefined operations, and
• implementing cartesian genetic programming on the set of predefined operations and the dataset to obtain a trained conversion function maximizing a performance criteria for the device for estimating,
• a use phase during which the trained conversion function is used, the use phase comprising the steps of:
• providing real incoming data,
• applying the trained conversion function on the real incoming data, to obtain real input data, and
• applying the estimating function on the real input data, to obtain the estimated physical value.
