Mish

Versioned name: Mish-4

Category: Activation

Short description: Mish is a Self Regularized Non-Monotonic Neural Activation Function.

Detailed description: Mish is a self regularized non-monotonic neural activation function proposed in the article.

Attributes: operation has no attributes.

Inputs:

• 1: Input tensor x of any floating point type T. Required.

Outputs:

• 1: Floating point tensor with shape and type matching the input tensor.

Types

• T: any floating point type.

Mathematical Formulation

For each element from the input tensor calculates corresponding element in the output tensor with the following formula: \f[ Mish(x) = x*tanh(ln(1.0+e^{x})) \f]
