A Comprehensive Introduction to Different Types of Convolutions in Deep Learning | by Kunlun Bai |...
However, in our setting, 1\times1 convolutions have dual purpose: most critically, they are used mainly as dimension reduction modules to remove computational bottlenecks, that would otherwise limit the size of our networks. 3 Motivation and High Level Considerations 深度网络这些年,网络的一个趋势...
,则输入层的输出数据为 N\times H\times W\times 3 。 5.1.2 卷积层 卷积层(Convolution Layer)通常用作对输入数据进行特征提取,通过卷积核矩阵对原始数据中隐含关联性的一种抽象。卷积操作原理上其实是对两张像素矩阵进行点乘求和的数学操作,其中一个矩阵为输入的数据矩阵,另一个矩阵则为卷积核(滤波器或特征矩...

$1\times{1}$ 卷积,与标准卷积完全一样,唯一的特殊点在于卷积核的尺寸是$1\times{1}$ ,也就是不去考虑输入数据局部信息之间的关系,而把关注点放在不同通道间。当输入矩阵的尺寸为$3\times{3}$ ,通道数也为3时,使用4个$1\times{1}$卷积核进行卷积计算,最终就会得到与输入矩阵尺寸相同,通道数为4的输出...

One notices immediately that the 1×1 convolution is an essential part of the Inception module. It precedes any other convolution (3×3 and 5×5) and used four times in a single module, more than any other element. 人们立即注意到1×1卷积是Inception模块的重要组成部分。 它在任何其他卷积(3...

Dilated convolutions:(膨胀卷积,这个翻译不好) This can be very useful in some settings to use in conjunction with 0-dilated filters because it allows you to merge spatial information across the inputs much more agressively with fewer layers 功能主要是:高效地合并不同level的feature map infomnation...
新的架构利用两个操作:逐点组卷积(pointwise group convolution)和通道混洗(channel shuffle),与现有的其他SOTA模型相比,在保证精度的同时大大降低了计算量。ShuffleNet V1在ImageNet和MS COCO上表现出了比其他SOTA模型更好的性能。论文原文见附录。 介绍
