Abstract: 

The main shortcoming of deep learning methods is the inevitable requirement of large-scale labeled training data that need to be collected and annotated by costly human labor. Zero-shot learning aims to recognize objects with no training samples available by introducing semantic representations of classes. We propose two methods to tackle zero-shot learning problem from noisy text descriptions as semantic representations of classes. The first one is a visual-semantic embedding-based method that embeds visual data and semantic data to a shared embedding space, while connecting text terms to its relevant visual parts. The second one is a GAN(Generative Adversarial Network)-based method that is able to generate visual feature based on semantic information, and the synthetic visual features are then used as training samples for unseen class classification.
