tanhLayer

Hyperbolic tangent (tanh) layer

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'.

Properties

Name — Layer name

'' (default) | character vector | string scalar

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

Data Types: char | string

NumInputs — Number of inputs

1 (default)

This property is read-only.

Number of inputs of the layer. This layer accepts a single input only.

Data Types: double

InputNames — Input names

{'in'} (default)

This property is read-only.

Input names of the layer. This layer accepts a single input only.

Data Types: cell

NumOutputs — Number of outputs

1 (default)

This property is read-only.

Number of outputs of the layer. This layer has a single output only.

Data Types: double

OutputNames — Output names

{'out'} (default)

This property is read-only.

Output names of the layer. This layer has a single output only.

Data Types: cell
