ML-GCN.pytorch

PyTorch implementation of Multi-Label Image Recognition with Graph Convolutional Networks, CVPR 2019.

Update

1. In our original conference paper, we report the baseline classification results using GAP for comparison, because GAP is the default choice for feature aggregation in ResNet series. In our experiments, we found that replacing GAP with GMP leads to improved performance, and thus adopt GMP with our GCN method -- we regard GMP as one part of our method. For clarification, we re-run the baselines and here report the corresponding results in the following table.

Method COCO NUS-WIDE VOC2007 Res-101 GAP 77.3 56.9 91.7 Res-101 GMP 81.9 59.7 93.0 Ours 83.0 62.5 94.0

1. We correct the typos in Eq. (8) as follows.

Options

• lr: learning rate
• lrp: factor for learning rate of pretrained layers. The learning rate of the pretrained layers is lr * lrp
• batch-size: number of images per batch
• image-size: size of the image
• epochs: number of training epochs
