1. A method for operating a hearing device comprising an input transducer ( 1 ), an output transducer ( 3 ) and a signal processing unit ( 2 ) for processing an output signal of the input transducer ( 1 ) to obtain an input signal for the output transducer ( 3 ) by applying a transfer function to the output signal of the input transducer ( 1 ), the method comprising the steps of: extracting features (fv) of the output signal of the input transducer ( 1 ), classifying the extracted features (fv) by at least two classifying experts (E 1 ,. .. , Ek), weighting the outputs of the at least two classifying experts by a weight vector (w) in order to obtain a classifier output (co), adjusting at least some parameters of the transfer function in accordance with the classifier output (co), monitoring a user feedback (uf) that is received by the hearing device, and updating the weight vector (w) and/or at least one of the at least two classifying experts (E 1 ,. .. , Ek) in accordance with the user feedback (uf).
