Advanced exercise: The Example 05 program illustrates the work of an adaptive filter based on teaching a neural network instead of a working program designed for practical uses. The same network can be used to filter other signals, for example, electrocardiogram records. This signal in digital form is not at your disposal so try to use a properly modified network for other signals, for example, filter a sample of sound in the form of a WAV or MP3 file. How can a similar adaptive filter network be used for picture processing?
