Post Hoc Denoising

DrCoffey edited this page Jul 26, 2021 · 9 revisions

Detection in DeepSqueak v3 generally produces fewer false positives than v2, so a default post-hoc denoising network has not been included. A new post-hoc denoising network may be trained for recordings with particularly bad noise issues.

False positives may be automatically identified and rejected using a post-hoc neural network.

To use the post hoc denoiser:

  1. Select "Tools > Automatic Review > Post Hoc Denoising"

  2. In the list box, select the detection files to denoise. All noise events found will be classified as "Noise" and rejected.

To train a post hoc denoiser:

  1. Select "Tools > Network Training > Train Post Hoc Denoiser"

  2. In the list box, select the detection files to to use for training

    • Calls labeled as "Noise" are used as negative training sample

      • Tip: Use the custom label option to hand label noise. Make sure your "true" calls are well represented in the training set
    • Accepted calls not labeled as "Noise" are used as positive training samples.

  1. When training is finished, a save dialog box will appear to save the denoising network
