论文链接: Attentional Pooling for Action Recognition。 代码链接:github.com/rohitgirdhar, 采用TensorFlow和Slim来实现。 作者介绍:Rohit Girdhar, CMU 在读博士生,也是ActionVLAD的作者。 Second-order pooling 在CNN结构中,pooling层我们一般采用mean
相反,一种合理的近似方法可能是应用现成(自下而上)的显著性方法来限制特征被平均覆盖的空间区域。我们用现有的基于显著性的方法进行的初步实验并不乐观。 项目信息: 论文:Attentional Pooling for Action Recognition 代码:rohitgirdhar/AttentionalPoolingAction 项目地址:Attentional Pooling for Action Recognition...
Attentional Pooling for Action Recognition 简介 这是一篇NIPS的文章,文章亮点是对池化进行矩阵表示,使用二阶池的矩阵表示,并将权重矩阵进行低秩分解,从而使分解后的结果能够自底向上和自顶向下的解释,并巧用attention机制来解释,我感觉学到了很多东西,特别是张量分解等矩阵论的知识点。 基础概念 低秩分解 目的:去除...
Inspired by the recent advance in attentional pooling techniques in image classification and action recognition tasks, we propose the Generalized Attentional Pooling (GAP) based Convolutional Neural Network (CNN) algorithm for action recognition in still images. The proposed GAP-CNN can be formulated as...

Among them, Squeeze-and-Excitation Block (SE) [52] is widely used for various tasks thanks to its easiness of implementation. SE works in two steps. First, it uses global average pooling to obtain an information vector of feature maps from different channels. Then, it employs fully connected...

Mollahosseini [9] proposed a neural network for FER using two convolution layers, one max pooling layer, and four “inception” layers, i.e., sub-networks. Liu in [10] combined feature extraction and classification in a single looped network, citing the two parts’ needs for feedback from...
