Weight Initializers

Weight initializer is an instance of Initializer that destructively edits the contents of numpy.ndarray or cupy.ndarray. Typically, weight initializers are passed to __init__ of Link and initializes its the weights and biases.

Base class

chainer.Initializer

Initializes array.

Concrete initializers

chainer.initializers.Identity	Initializes array with the identity matrix.
chainer.initializers.Constant	Initializes array with constant value.
chainer.initializers.Zero	Returns initializer that initializes array with the all-zero array.
chainer.initializers.One	Returns initializer that initializes array with the all-one array.
chainer.initializers.Normal	Initializes array with a normal distribution.
chainer.initializers.GlorotNormal	Initializes array with scaled Gaussian distribution.
chainer.initializers.HeNormal	Initializes array with scaled Gaussian distribution.
chainer.initializers.Orthogonal	Initializes array with an orthogonal system.
chainer.initializers.Uniform	Initializes array with a scaled uniform distribution.
