curse of dimensionality 输入在p维立方体中符合均匀分布,如果需要覆盖比例r的体积,需要每个维度上\(e_p(r)=r^{1/p}\) \(e_{10}(0.01)=0.63,e_{10}(0.1)=0.8\) 输入在p维立方体中负荷均匀分布,p=1时,1000个点达到的采样密度 在p=10时,需要\(1000^{10}\)个点才能达到 需要的数据量随维度增加幂增长 输入在p维单位球体中符合均匀分布,使用1-nearest neighbor预测0点的値 假设有N个训练数据,…

26 THINGS I LEARNED IN THE DEEP LEARNING SUMMER SCHOOL In the beginning of August I got the chance to attend the Deep Learning Summer School in Montreal. It consisted of 10 days of talks from some of the most well-known neural network researchers. Du…

0 Java反射机制 反射(Reflection)是 Java 的高级特性之一,是框架实现的基础. 0.1 定义 Java 反射机制是在运行状态中,对于任意一个类,都能够知道这个类的所有属性和方法:对于任意一个对象,都能够调用它的任意一个方法和属性:这种动态获取的信息以及动态调用对象的方法的功能称为 Java 语言的反射机制. 一般而言,当用户使用一个类的时候,应该获取这个类,而后通过这个类实例化对象,但是使用反射则可以相反的通过对象获取类中的信息. 通俗的讲反射就是可以在程序运行的时候动态装载…

第一部分: C#是一种通用的,类型安全的,面向对象的编程语言.有如下特点: (1)面向对象:c# 是面向对象的范例的一个丰富实现, 它包括封装.继承和多态性.C#面向对象的行为包括: 统一的类型系统 类与接口 属性.方法.事件 (2)类型安全:C#还允许通过dynamic关键字动态指定类型. 但是,C#仍然是一个主要的静态类型语言.之所以是一种强类型的语言,是因为它的类型规则是非常严格的,例如,不能够使用一个float类型的参数去调用一个解释int 类型的函数,除非显式的把float转换为int…
