NAME
Peta::NN::Layer::Activation - relu, tanh and sigmoid
VERSION
version 0.2610090
SYNOPSIS
my $net = Peta::NN->new(input => 4, layers => [ [dense => 2] ]); # as one of:
layers => [ [dense => 8], 'tanh', [dense => 2] ]DESCRIPTION
Written as the bare string 'relu', 'tanh' or 'sigmoid' in a network's layer list.
METHODS
A layer is made and driven by Peta::NN; these are what the network calls.
new
The layer, from what its entry in the layer list says.
type
The layer's kind, as a model file names it.
init
init($n_in, $rng, $backend): sets the layer up for its input size and returns its output size.
param_names
The names of the layer's parameter tensors.
forward
The layer's output for a batch.
backward
Takes the gradient of the output, leaves the gradients of the parameters with the layer, and returns the gradient of the input.
spec
The layer as it is written in a layer list.
kinds
The activations there are.
