cross_entropy< Backend, Matrix > 模板结构体 参考

详细描述

template<enum Backend, class Matrix>
struct shogun::linalg::implementation::special_purpose::cross_entropy< Backend, Matrix >

Generic class which is specialized for different backends to perform the cross_entropy operation

在文件 implementation/SpecialPurpose.h 第 426 行定义.

Public 类型
typedef Matrix::Scalar	T

静态 Public 成员函数
static T	compute (Matrix P, Matrix Q)

成员类型定义说明

typedef Matrix::Scalar T

Scalar type

在文件 implementation/SpecialPurpose.h 第 429 行定义.

成员函数说明

static T compute ( Matrix  P, Matrix  Q  )

static

Returns the cross entropy between P and Q. The cross entropy is defined as \( H(P,Q) = - \sum_{ij} P[i,j]log(Q[i,j]) \)
