In the sea–land clutter classification of sky-wave over-the-horizon-radar (OTHR), the imbalanced and scarce data lead to a poor performance of the deep learning-based classification model. To solve ...

Classification problems in which the number of features (dimensions) is unduly higher than the number of samples (observations) is an essential research and application area in a variety of domains, ...

In this article, in order to better handle this problem, a novel generative model named the conditional variational autoencoder with an adversarial training process (CVA 2 E) is proposed for ...
