- Abstract:
-
Zero-shot learning algorithms aim to address the challenge of image recognition with limited or even missing samples. By transforming the problem into a supervised learning task through the use of generative models, the method generates images of missing classes. However, the quality of generated images can be inconsistent and is susceptible to pattern collapse, affecting image recognition accuracy. To address this issue, we propose an improved zero-shot learning image recognition method based on an improved TransGAN. The generator of TransGAN is linked to a convolutional layer for dimensionality reduction, leading to a more effective extraction of image features and improved stability. Moreover, the addition of a nonlinear activation function to the discriminator and simplifying its structure enhances its ability to guide the generator and reduces computational requirements. Experiment results on public datasets show that our proposed method increases image recognition accuracy by 29.02% compared to the baseline model and demonstrates improved generalization performance.
