Relationships encode the interactions among individual instances and play a critical role in deep visual scene understanding. Suffering from the high predictability with non-visual information, relationship models tend to fit the statistical bias rather than ``learning" to infer the relationships from images. To encourage further development in visual relationships, we propose a novel method to mine more valuable relationships by automatically pruning visually-irrelevant relationships. We construct a new scene graph dataset named Visually-Relevant Relationships Dataset (VrR-VG) based on Visual Genome. Compared with existing datasets, the performance gap between learnable and statistical method is more significant in VrR-VG, and frequency-based analysis does not work anymore. Moreover, we propose to learn a relationship-aware representation by jointly considering instances, attributes and relationships. By applying the representation-aware feature learned on VrR-VG, the performances of image captioning and visual question answering are systematically improved, which demonstrates the effectiveness of both our dataset and features embedding schema.
Visual-relevance Relationships dataset (VrR-VG) is a scene graph dataset from Visual Genome. It contains 117 visual-relevant relationships selected by our method.
VrR-VG is constructed from Visual Genome. The VrR-VG has 58983 images and 23375 relation pairs. Excluded positional and statistiaclly biased reltionships, the VrR-VG is more balance and includes more valuable relaiton data.Rather than generating scene graph dataset by relation label frequency, the VrR-VG gathers visual-relevant relationships, like "play with", "lay on", "hang on", etc. The relationships like "on" , "wearing", "has", etc., which can be inferred by positional information or data bias, are excluded in our dataset. The VrR-VG offers a more balanced research material for relationships, and more diverse relation data for semantic tasks.
