Calls may be classified with a supervised neural network. This network operates on the spectrogram, rather than the contour.

To use a supervised classifier:

1. Select "Tools > Call Classification > Supervised Classification"
2. In the list box, select the detection files to classify, and click "OK".

To train a supervised classifier:

1. Select "Tools > Network Training > Train Supervised Classifier"
2. Select the detection files to to use for training.

• Rejected calls and "Noise" labeled calls will be ignored.

3. When training is finished, the new network will be automatically saved as "DeepSqueak\Denoising Networks\CleaningNet.mat".

• Training will overwrite the older network. It is wise to create a backup of the old network.

4. Specify the spectrogram frequency range, and click "OK".
5. Save the network when training finishes.
