selu function

VARP selu(
  1. VARP features,
  2. double scale,
  3. double alpha
)

Computes scaled exponential linear: scale * alpha * (exp(features) - 1) if < 0, scale * features otherwise.

Args:

  • features: A variable of type Halide_Type_Float
  • scale: Scaling factor (positive float)
  • alpha: Alpha factor (positive float)

Returns:

  • A variable. Has the same type as features.

Implementation

VARP selu(VARP features, double scale, double alpha) =>
    VARP.fromPointer(C.mnn_expr_Selu(features.ptr, scale, alpha));
