Domain-robust VQA with Diverse Datasets and Methods but No Target Labels

The observation that computer vision methods overfit to dataset specifics has inspired diverse attempts to make object recognition models robust to domain shifts. However, similar work on domain-robust visual question answering methods is very limited. VQA domain adaptation differs from that of object recognition due to additional complexity: VQA models handle multimodal inputs, methods contain multiple steps with diverse modules resulting in complex optimization, and answer spaces in different datasets are vastly different. To tackle these challenges, we identify domain shifts in VQA, and analyze the efficacy of various domain adaptation methods. First, we quantify existing domain shifts between popular VQA datasets, in both visual and textual space. We then construct synthetic datasets shifts in both the image and question domains. Second, we test the robustness of different families of VQA methods (classic two-stream, transformer, and neuro-symbolic methods) to domain shifts. We develop methods to bridge VQA domain gaps through unified domain adaptation methods. Third, to emulate the setting of a real-world generalization, we investigate methods without target labels and the challenging open-ended task formulation.
