cs231n --- 3 : Convolutional Neural Networks (CNNs / ConvNets)

CNN介绍 与之前的神经网络不同之处在于,CNN明确指定了输入就是图像,这允许我们将某些特征编码到CNN的结构中去,不仅易于实现,还能极大减少网络的参数. 一. 结构概述 与一般的神经网络不同,卷积神经网络尤其特殊之处.一般的神经网络每一层与前一层之间采用全连接:一层中的神经元之间也是互相独立的,并不共享权值:最后一层全连接层陈伟输出层,在分类任务中出表示类别得分.CIFAR-10中图像是32*32*3=3072,所以,与输入相连的第一个隐层的每个神经元的参数都有3072个,如果图像尺寸更大,那…

Convolutional Neural Networks for Visual Recognition 8

Convolutional Neural Networks (CNNs / ConvNets) 前面做了如此漫长的铺垫,现在终于来到了课程的重点.Convolutional Neural Networks, 简称CNN,与之前介绍的一般的神经网络类似,CNN同样是由可以学习的权值与偏移量构成,每一个神经元接收一些输入,做点积运算加上偏移量,然后选择性的通过一些非线性函数,整个网络最终还是表示成一个可导的loss function,网络的起始端是输入图像,网络的终端是每一类的预测值,通过一个ful…

Convolutional Neural Networks

卷积神经网络(Convolutional Neural Networks/ CNN/ConvNets) 卷积神经网络和普通神经网络十分相似: 组成它们的神经元都具有可学习的权重(weights)和偏置(biases).每个神经元接受一些输入,执行一个点积操作,并且可能执行一个非线性函数最后得到该神经元的输出.整个网络仍然可以表示为一个可微评分函数.这个函数在一端输入图像的像素,在另一端得到某个类别的分数.同时卷积神经网络在做后一个层(fully-connected)上仍然具有损失函数--例如SV…
