S3Pool: Pooling with Stochastic Spatial Sampling CVPR2017https://github.com/Shuangfei/s3pool 本文将常规池化看作两个步骤: 1)以步长为1在特征图上滑动池化窗口,尺寸大小基本保持不变, leaves the spatial resolution intact 2)以一种 uniform 和 deterministic 的方式进行降采样 我们认为这种 uniform 和 determin...
Moreover, bilinear upsampling is integrated to avoid checkerboard artefacts, and convolutional layers performs downsampling operations instead of pooling to avoid losing critical features.

a similarity metric and an algorithm to robustly and efficiently compute the COVET metric. The COVET framework assumes that the interplay between the cell and its environment creates covarying patterns of expression between the cell and its niche, which can be formulated via the gene–gene covarianc...
The pooling layer performs downsampling by reducing the size of feature map. After feature extraction, this can be done using a fully connected neural network to divide the data into various classes. Graph Convolutional Network (GCN) is a very overwhelming neural network architecture for deep ...
Strip Pooling: Rethinking Spatial Pooling for Scene Parsing Qibin Hou1 Li Zhang2 Ming-Ming Cheng3 Jiashi Feng1 1National University of Singapore 2University of Oxford 3CS, Nankai University Abstract Spatial pooling has been proven highly effective in cap- turing long-range co...
As a result, we introduce dilated convolution to avoid down-sampling and retain internal data structures. After concatenating the results of dilated convolution and a series of operations such as relu and normalization, the spatial attention weights are obtained and then multiplied by the preliminarily...
Different from the pyramid pooling module in [5], we build our spatial pyramid simply by down-sampling and up-sampling processes on the final predicting feature maps. We directly perform graph reasoning on each of the scale and aggregate them in order to capture sufficient long-range contextual...

{N}\). To generate a subsampled version of the kNN graph, we use a graph coarsening algorithm80, which pools nodes together based on their connectivity pattern, similarly to how image downsampling groups pixels together (Fig.2c). We iteratively coarsen and blur the graph four times by a ...
