Hyperbolic tangent (tanh) layer

expand all in page

Description

A hyperbolic tangent (tanh) activation layer applies the tanh function on the layer inputs.

Creation

Syntax

layer = tanhLayer
layer = tanhLayer('Name',Name)

Description

layer = tanhLayer creates a hyperbolic tangent layer.

layer = tanhLayer('Name',Name) additionally specifies the optional Name property. For example, tanhLayer('Name','tanh1') creates a tanh layer with the name 'tanh1'.

Layer name, specified as a character vector or string scalar. For Layer array input, the trainnet and dlnetwork functions automatically assign names to layers with the name "".

The TanhLayer object stores this property as a character vector.

Data Types: char | string

This property is read-only.

Number of inputs to the layer, returned as 1. This layer accepts a single input only.

Data Types: double

This property is read-only.

Input names, returned as {'in'}. This layer accepts a single input only.

Data Types: cell

This property is read-only.

Number of outputs from the layer, returned as 1. This layer has a single output only.

Data Types: double

This property is read-only.

Output names, returned as {'out'}. This layer has a single output only.
