池化层(Pooling layer)同样是收到了视觉神经科学的启发.在初级视觉皮层V1(Primary visual cortex)中,包含了许多复杂细胞(Complex cells),这些细胞对于图像中物体微小的变化具有不变性(invariance to small shifts and distortions). 这种不变性也是Pooling layer的核心,我们首先来看Pooling layer如何工作,然后具体分析这种不变性. 我们举例说明Pooling layer的工作过程,在下图中…

When we hear about Convolutional Neural Network (CNNs), we typically think of Computer Vision. CNNs were responsible for major breakthroughs in Image Classification and are the core of most Computer Vision systems today, from Facebook’s automated pho…

About this Course This course will teach you how to build convolutional neural networks and apply it to image data. Thanks to deep learning, computer vision is working far better than just two years ago, and this is enabling numerous exciting applica…

零.说明: 本文的所有代码均可在 DML 找到,欢迎点星星. 注.CNN的这份代码非常慢,基本上没有实际使用的可能,所以我只是发出来,代表我还是实践过而已 一.引入: CNN这个模型实在是有些年份了,最近随着深度学习的兴起又开始焕发青春了,把imagenet测试的准确度提高了非常多,一个是Alex的工作,然后最近好像Zeiler又有突破性的成果,可惜这些我都没看过,主要是imagenet的数据太大了,我根本没有可能跑得动,所以学习的积极性有些打折扣.不说那么多,还是先实现一个最基础的CNN再说吧…
