Zero-sample image classification method based on variational self-coding adversarial network

Abstract

The invention discloses a zero-sample image classification method based on a variational self-coding adversarial network. Two variational auto-encoders of a visual mode and a semantic mode are constructed, and visual features and semantic features are respectively and correspondingly used as inputs of the two variational auto-encoders; pseudo visual features and semantic features are generated, finally, the true visual features and the generated semantic features are input into a discriminator, and the adversarial process is completed through a metric learning method. Then starting to train asoftmax classifier, inputting the visual features of the non-visible class images into a variational auto-encoder of a visual mode, and training the classifier by utilizing the generated pseudo visualfeatures and corresponding labels; during testing, the real visual features of the non-visible class samples are input into the classifier for classification, and a zero-sample image classification task is realized. The method can achieve the classification task in a more real scene, facilitates the promotion of the application of zero-sample learning to the production and living reality, and accelerates the practical development of a deep learning algorithm.
