# fann_get_activation_function

(PECL fann >= 1.0.0)

fann_get_activation_function — Returns the activation function

### 説明

int fann_get_activation_function ( resource `$ann` , int `$layer` , int `$neuron` )

Get the activation function for neuron number neuron in layer number layer, counting the input layer as layer 0.

It is not possible to get activation functions for the neurons in the input layer.

The return value is one of the activation functions constants.

### パラメータ

`ann`

  ニューラルネットワークリソース。

`layer`

  Layer number.

`neuron`

  Neuron number.

### 返り値

Learning functions constant or -1 if the neuron is not defined in the neural network, or `FALSE` on error.
