下列哪个函数不是常用的神经网络激活函数______。
A: y = 3x
B: y = ReLU(x)
C: y = Sigmoid (x)
D: y = tanh(x)
A: y = 3x
B: y = ReLU(x)
C: y = Sigmoid (x)
D: y = tanh(x)
举一反三
- 下列语句正确的是( ) A: If x<3*y And x>y Then y=3x B: If x<3*y And x>y Then y=x^3 C: If x<3*y : x>y Then y=x^3 D: If x<3*y And x>y Then y=x**3
- 函数y=3x的反函数是() A: y=(1/3)x(x>0) B: -y=(1/3)x(x>0) C: y=log3x(x>0) D: -y=-log3x(x>0)
- 下列函数中,()不是基本初等函数。 A: y=exp(-x) B: y=erf(x) C: y=tan(x) D: y=x^5/3
- 求下列函数的值域:(1)y=(x^2+2x+3)/x^2;(2)y=(x^2-3x+4)/x;(3)y=3x/(2x^2-1),x∈[2,4]
- 如下C程序的输出是什么?#include [stdio.h]void Func1 (int x, int y);void Func2 (int *x, int *y); int main() { int x = 3; int y = 4;Func1 (x, y); printf ("x = %d, y = %d\n", x, y);Func2(&x, &y); printf ("x = %d, y = %d\n", x, y);} void Func1 (int x, int y) { x = x + y; y = x - y; x = x - y; printf ("x = %d, y = %d\n", x, y);} void Func2 (int *x, int *y) { *x = *x + *y; *y = *x - *y; *x = *x - *y;;} A: x = 3, y = 4x = 3, y = 4x = 3, y = 4 B: x = 4, y = 3x = 4, y = 3x = 4, y = 3 C: x = 3, y = 4x = 3, y = 4x = 4, y = 3 D: x = 4, y = 3x = 3, y = 4x = 4, y = 3
