Validation accuracy of the CNNs trained using both amplitude and phase features, or either amplitude or phase feature on the prediction of the incident angle of (a) one single-frequency source and (b) two simultaneously active single-frequency sources. The black curves show the validation accuracy corresponding to the reference sensor trained by using both features.
