一.C++ vector::data()函数 返回值类型:vector的基类 返回值:Returns a pointer such that [data(), data() + size()] is a valid range. For a non-empty %vector, data() == &front(). 等价于:&vector::front() 例子 //基类型定义 class Token { private: int lineshow; //记录该单词在原程序中的行数 st
input: import data 2. transpose the data 3. reshape the data into array code: matlab load x.dat X=x.dat; X=X.' % transpose; x_array=reshape(X, 499, [])
1. 包含一个头文件: 1 #include <vector> 2. 申明及初始化: std::vector<int> first; // empty vector of ints std::vector<,); // four ints with value 100 std::vector<int> third (second.begin(),second.end()); // iterating through second std::vector<in

Traditionally, many classification problems try to solve the two or multi-class situation. The goal of the machine learning application is to distinguish test data between a number of classes, using training data. But what if you only have data of on
Open Data for Deep Learning Here you’ll find an organized list of interesting, high-quality datasets for machine learning research. We welcome your contributions for curating this list! You can find other lists of such datasets on Wikipedia, for exam

An array (vector) is a common-place data type, used to hold and describe a collection of elements. These elements can be fetched at runtime by one or more indices (identifying keys). A distinguishing feature of an array compared to a list is that the
前言: CNN作为DL中最成功的模型之一,有必要对其更进一步研究它.虽然在前面的博文Stacked CNN简单介绍中有大概介绍过CNN的使用,不过那是有个前提的:CNN中的参数必须已提前学习好.而本文的主要目的是介绍CNN参数在使用bp算法时该怎么训练,毕竟CNN中有卷积层和下采样层,虽然和MLP的bp算法本质上相同,但形式上还是有些区别的,很显然在完成CNN反向传播前了解bp算法是必须的.本文的实验部分是参考斯坦福UFLDL新教程UFLDL:Exercise: Convolutional Ne
