Forest R-CNN: Large-Vocabulary Long-Tailed Object Detection and Instance Segmentation

1 code implementation13 Aug 2020 Jialian Wu, Liangchen Song, Tiancai Wang, Qian Zhang, Junsong Yuan

In the classification tree, as the number of parent class nodes are significantly less, their logits are less noisy and can be utilized to suppress the wrong/noisy logits existed in the fine-grained class nodes.
