前言:好久不见了,最近一直瞎忙活,博客好久都没有更新了,表示道歉.希望大家在新的一年中工作顺利,学业进步,共勉! 今天我们介绍深度神经网络的缺点:无论模型有多深,无论是卷积还是RNN,都有的问题:以图像为例,我们人为的加一些东西,然后会急剧的降低网络的分类正确率.比如下图: 在生成对抗样本之后,分类器把alps 以高置信度把它识别成了狗,下面的一幅图,是把puffer 加上一些我们人类可能自己忽视的东西,但是对分类器来说,这个东西可能很重要,这样分类器就会去调节它,这就导致分类器以百分之百的置信…

When a golf player is first learning to play golf, they usually spend most of their time developing a basic swing. Only gradually do they develop other shots, learning to chip, draw and fade the ball, building on and modifying their basic swing. In a…

Learning Multi-Domain Convolutional Neural Networks for Visual Tracking CVPR 2016 本文提出了一种新的CNN 框架来处理跟踪问题.众所周知,CNN在很多视觉领域都是如鱼得水,唯独目标跟踪显得有点“慢热”,这主要是因为CNN的训练需要海量数据,纵然是在ImageNet 数据集上微调后的model 仍然不足以很好的表达要跟踪地物体,因为Tracking问题的特殊性,至于怎么特殊的,且听细细道来. 目标跟踪之所以很少被 C…
