dPReLU function

Derivatives Parametric ReLU Activation Function

dPReLU(x, alpha = 1)

dPReLUa(x, alpha = 1)

dPReLUa1(x, alpha = 1)

Arguments

• x: A numeric vector. All elements must be finite and non-missing.
• alpha: A numeric scalar. All elements must be finite and non-missing.

Returns

A numeric vector where the derivative(s) of the ELU function has been applied to each element of x.

Examples

dPReLU(c(-1, 0, 1, 2), 2)
dPReLUa(c(-1, 0, 1, 2), 2)
dPReLUa1(c(-1, 0, 1, 2), 2)

# Can also be used in rxode2:
r <- rxode2({
  r1=dPReLU(time, 2)
  r2a=dPReLUa(time, 2)
  ra=dPReLUa1(time, 2)
})

e <- et(c(-1, 0, 1, 2))
rxSolve(r, e)
