Python / Numpy Review Session(Python/Numpy复习课) 二、Deep Learning Basics Lecture 2: Image Classification with Linear Classifiers(用线性分类器进行图像分类) 图像是一个张量,它是介于[0,255]之间的整数。 面临一些挑战:视角变化(当相机移动时,所有的像素都改变了!)、明亮程度、背景混杂、图像遮挡、变形、同...
编程能力好差,之前做课题,打比赛是都调包,pandas用的还算可以,找工作面试直接问实现过啥算法没有,汗汗...表示编程能力差啊,数据结构也没学过啊,deeplearning.ai-作业会把所有的作业都帖出来,作为锻炼自己的编程能力。 这次作业使用到的函数工具都是Building your Deep Neural Network: Step by Step这次作业中的函...

Deep learning has been very successful on image classification tasks in the past few years, because it allows to develop end-to-end solutions, taking as input the raw images in form of a grid of pixels and returning the class assignments. Semantic Based Regularization is used in this paper ...
从上图可以看到,PCANet的训练分为三个步骤(stage),前两个stage很相似,都是去平均,然后PCA取主成分并卷积,最后一步是二值化(为了产生非线性输出)和直方图量化。 设滤波器个数为f, 1、过滤器的计算:对图片均匀分块,去均值,然后求每块的特征向量和特征值,然后对特

1 上采样与下采样 缩小图像(或称为下采样(subsampled)或降采样(downsampled))的主要目的有两个: 下采样原理:对于一幅图像I尺寸为M*N,对其进行s倍下采样,即得到(M/s)*(N/s)尺寸的得分辨率图像,当然s应该是M和N的公约数才行,如果考虑的是矩阵形式的图像,就是把原
