Choose an App to Label Ground Truth Data

Decide which app to use to label ground truth data: Image Labeler, Video Labeler, Ground Truth Labeler, Lidar Labeler, Signal Labeler, or Audio Labeler.

Radar and Communications Waveform Classification Using Deep Learning (Phased Array System Toolbox)

This example shows how to classify radar and communications waveforms using the Wigner-Ville distribution (WVD) and a deep convolutional neural network (CNN).

Music Genre Classification Using Wavelet Time Scattering (Wavelet Toolbox)

This example shows how to classify the genre of a musical excerpt using wavelet time scattering and the audio datastore.

Wavelet Time Scattering Classification of Phonocardiogram Data (Wavelet Toolbox)

This example shows how to classify human phonocardiogram (PCG) recordings using wavelet time scattering and a support vector machine (SVM) classifier.
