Instance Method Summary

• #init_param(layer, param) ⇒ Object

  Initialization of learning parameters.

Constructor Details

#initialize(seed: false) ⇒ Initializer

Returns a new instance of Initializer.

Parameters:

• seed (Boolean | Integer) (defaults to: false) —

  Seed of random number used for initialize parameter. Set true to determine seed as random.

# File 'lib/dnn/core/initializers.rb', line 7

def initialize(seed: false)
  @seed = seed == true ? rand(1 << 31) : seed
end

Instance Method Details

#init_param(layer, param) ⇒ Object

Initialization of learning parameters.

Parameters:

• layer (DNN::Layers::Layer) —

  Layer that owns learning parameters.

• param (DNN::Param) —

  Learning parameter to be initialized.

Raises:

• (NotImplementedError)

# File 'lib/dnn/core/initializers.rb', line 14

def init_param(layer, param)
  raise NotImplementedError.new("Class '#{self.class.name}' has implement method 'init_param'")

#to_hash(merge_hash = nil) ⇒ Object

# File 'lib/dnn/core/initializers.rb', line 18

def to_hash(merge_hash = nil)
  hash = { class: self.class.name, seed: @seed }
  hash.merge!(merge_hash) if merge_hash
