It is understood that most times the output (y) can be dependent on the input (x). My question; is it possible to predict an output with 'no given data' from a set of inputs with available data? For instance, if you want to predict the the torque of an engine (output1, with data) using the fueling level and engine speed as inputs, is it also possible to predict the emission levels (output2, without data) using the same set of inputs?
Thank you!
