论文笔记之：Decoupled Deep Neural Network for Semi-supervised Semantic Segmentation

文章来源:CVPR2014 作者:Zhenyao Zhu,Ping Luo,Xiaogang Wang,Xiaoou Tang (香港中文大学果然牛啊,CVPR一刷一大堆) 主要内容: 提出了利用深度学习(还是CNN)来进行人脸图像重构正面人脸,然后利用重构的正面人脸图像来进行人脸的verification,当然能够取得更高的准确率(比没有用正脸去verification),文章提出利用DL来学习从任意脸到canonical 脸的转换,可以认为是一个回归问题(也不一定非得用DL方法来做). 现有

Deep Attributes Driven Multi-Camera Person Re-identification 2017-06-28  21:38:55    [Motivation] 本文的网络设计主要分为三个部分: Stage 1: Fully-supervised dCNN training Stage 2: Fine-tuning using attributes triplet loss Stage 3:Final fine-tuning on the combined da

The state of the art of non-linearity is to use ReLU instead of sigmoid function in deep neural network, what are the advantages? I know that training a network when ReLU is used would be faster, and it is more biological inspired, what are the other

Deep Learning: Assuming a deep neural network is properly regulated, can adding more layers actually make the performance degrade? I found this to be really puzzling. A deeper NN is supposed to be more powerful or at least equal to a shallower NN. I

Building your Deep Neural Network: Step by Step Welcome to your third programming exercise of the deep learning specialization. You will implement all the building blocks of a neural network and use these building blocks in the next assignment to bui

Deep Neural Network - Application Congratulations! Welcome to the fourth programming exercise of the deep learning specialization. You will now use everything you have learned to build a deep neural network that classifies cat vs. non-cat images. In

Welcome to your week 4 assignment (part 1 of 2)! You have previously trained a 2-layer Neural Network (with a single hidden layer). This week, you will build a deep neural network, with as many layers as you want! In this notebook, you will implement

When you finish this, you will have finished the last programming assignment of Week 4, and also the last programming assignment of this course! You will use use the functions you'd implemented in the previous assignment to build a deep network, and

动机(Motivation) 对于非线性分类问题,如果用多元线性回归进行分类,需要构造许多高次项,导致特征特多学习参数过多,从而复杂度太高. 神经网络(Neural Network) 一个简单的神经网络如下图所示,每一个圆圈表示一个神经元,每个神经元接收上一层神经元的输出作为其输入,同时其输出信号到下一层,其中每一层的第一个神经元称为bias unit,它是额外加入的其值为1,通常用+1表示,下图用虚线画出. 符号说明: $a_i^{(j)}$表示第j层网络的第i个神经元,例如下图$a_1^{(
