• Abstract summary: Scene Graph Generation (SGG) aims to build a structured representation of a scene using objects and pairwise relationships. We propose Resistance Training using Prior Bias (RTPB) for the scene graph generation. Our RTPB achieves an improvement of over 10% under the mean recall when applied to current SGG methods.

• Abstract: Scene Graph Generation (SGG) aims to build a structured representation of a scene using objects and pairwise relationships, which benefits downstream tasks. However, current SGG methods usually suffer from sub-optimal scene graph generation because of the long-tailed distribution of training data. To address this problem, we propose Resistance Training using Prior Bias (RTPB) for the scene graph generation. Specifically, RTPB uses a distributed-based prior bias to improve models' detecting ability on less frequent relationships during training, thus improving the model generalizability on tail categories. In addition, to further explore the contextual information of objects and relationships, we design a contextual encoding backbone network, termed as Dual Transformer (DTrans). We perform extensive experiments on a very popular benchmark, VG150, to demonstrate the effectiveness of our method for the unbiased scene graph generation. In specific, our RTPB achieves an improvement of over 10% under the mean recall when applied to current SGG methods. Furthermore, DTrans with RTPB outperforms nearly all state-of-the-art methods with a large margin.

  Scene graph generation aims to capture detailed spatial and semantic relationships between objects in an image. Existing Transformer-based methods either employ distinct queries for objects and predicates or utilize holistic queries for relation triplets. We present a new Transformer-based method, called DSGG, that views scene graph detection as a direct graph prediction problem.

  We show that it is sub-optimal to directly transfer existing PEFTs to graph-based tasks due to the issue of feature distribution shift. We propose a novel structure-aware PEFT approach, named G-Adapter, to guide the updating process. Extensive experiments demonstrate that G-Adapter obtains the state-of-the-art performance compared to the counterparts on nine graph benchmark datasets.
