Graph neural networks (GNNs) have significantly improved the representation power for graph-structured data. Despite of the recent success of GNNs, the graph convolution in most GNNs have two limitations. Since the graph convolution is performed in a small local neighborhood on the input graph, it is inherently incapable to capture long-range dependencies between distance nodes. In addition ....

. In this paper, we propose a deformable deep convo-lutional neural network for object detection; named as DeepID-Net. In DeepID-Net, we jointly learn the fea-ture representation and part deformation for a large num-ber of object categories. We also investigate many as-pects in effectively and efficiently training and aggregating. Here, we investigate a supervised machine learning approach based on deformable convolutional neural networks (deCNNs) and transfer learning to forecast the North Atlantic-European weather regimes.

摘要:Deformable DETR提出了一种新玩法:它借鉴了DCN的思想,提出可变形注意力机制——每个特征像素不必与所有特征像素交互计算,只需要与部分基于采样获得的其它像素交互,并且这些采样点的位置是可学习的。. To address this problem, bilinear interpolation is used. Deformable RoI pooling is also used, which greatly improves object detection. Deformable ConvNets adaptively select the important regions and enlarge the valid receptive field of convolutional neural networks; this is important in object detection and semantic segmentation tasks. Deformable Convolutional Networks The feature maps and convolution are 3D. Both de- formable convolution and RoI pooling modules operate on the 2D spatial domain. The operation remains the same across the channel dimension. For simplicity, the modules are described in 2D. Extension to 3D is straightforward. conv o・ set ・‘ld input feature map 2N.

To accommodate defects of different shapes, we introduce deformable convolutions in the backbone network. The idea of deformable convolution is very simple, that is, the original fixed-shape convolution kernel becomes variable. Taking the 3 × 3 convolution kernel as an example, the mathematical expression is as follows:. 3240 Commits. 35 Branches. 160 MB. Deformable Convolution Introduced by Dai et al. in Deformable Convolutional Networks Edit Deformable convolutions add 2D offsets to the regular grid sampling locations in the standard convolution. It enables free form deformation of the sampling grid. The offsets are learned from the preceding feature maps, via additional convolutional layers.
