The paper introduces a novel framework for zero-shot learning (ZSL) that aims to recognize new categories that are unseen during training. The key strategies of the proposed method are:
Utilizing the knowledge of ChatGPT and the image generation capabilities of DALL-E to create reference images that can precisely describe unseen categories and classification boundaries, thereby alleviating the information bottleneck issue.
Integrating the results of text-image alignment and image-image alignment from CLIP, along with the image-image alignment results from DINO, to achieve more accurate predictions.
Introducing an adaptive weighting mechanism based on confidence levels to aggregate the outcomes from different prediction methods.
Experiments on CIFAR-10, CIFAR-100, and TinyImageNet datasets demonstrate that the proposed method can significantly improve classification accuracy compared to single-model approaches. It achieves AUROC scores above 96% across all test datasets, and notably surpassing 99% on the CIFAR-10 dataset.
The paper provides an in-depth analysis of the strengths and limitations of individual models, as well as the effectiveness of different fusion strategies. It highlights the importance of leveraging the complementary capabilities of multiple models to enhance the overall performance, particularly in handling unseen or ambiguous categories.
