1. A method of operating a hearing device, the hearing device having a microphone for receiving ambient sound, a signal processor for processing a microphone signal based on the received ambient sound into an output signal, a speaker for outputting the output signal, and the signal processor including a feedback canceller for determining and, if present, canceling feedback, the method comprising:
retrieving for a predetermined sample period a set of data of the feedback canceller that represents an acoustic feedback path between the speaker and the microphone;
applying at least one step of reducing an amount of data within the set of data;
applying a denoising step to the set of data;
generating a representative set that is representative for the data within the set of data;
inputting, directly or indirectly, the representative set to a neural network that is trained to retrieve from the input data a measure indicating a proper positioning or an improper positioning of the hearing device within the ear canal; and
issuing a notice to a user of the hearing device when the measure indicates an improper positioning of the hearing device.
