JDK版本 Vector简介 /** * The {@code Vector} class implements a growable array of * objects. Like an array, it contains components that can be * accessed using an integer index. However, the size of a * {@code Vector} can grow or shrink as needed to accom
Neural Machine Translation Welcome to your first programming assignment for this week! You will build a Neural Machine Translation (NMT) model to translate human readable dates ("25th of June, 2009") into machine readable dates ("2009-06-25
Majority Element 本题收获: 1.初步了解hash,nth_element的用法 2.题目的常规思路 题目: Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority
List概览 List,正如它的名字,表明其是有顺序的.当讨论List的时候,最好拿它跟Set作比较,Set中的元素是无序且唯一:下面是一张类层次结构图,从这张图中,我们可以大致了解java集合类的整体架构: ArrayList vs LinkedList vs Vector 从上面的类层次结构图中,我们可以发现他们都实现了List接口,它们使用起来非常相似.区别主要在于它们各自的实现,不同的实现导致了不同的性能和不同的操作. ArrayList是为可变数组实现的,当更多的元素添加到ArrayL
今天给大家介绍一下one class classification以及用SVDD(support vector domain description)做one class classification.最近接触了一下one class classification,挺有意思的,和多类classification的思路还是有很大差别,比较长姿势~ 我们知道,classification问题一般都是2类及2类以上的,典型的2类问题比如识别一封邮件是不是垃圾邮件,这里就只有2类,"是"或者&
SVMs are considered by many to be the most powerful 'black box' learning algorithm, and by posing构建 a cleverly-chosen optimization objective优化目标, one of the most widely used learning algorithms today. 第一节 向量的内积(SVM的基本数学知识) Support Vector Machines 支持向
