chainer.initializers.LeCunUniform

class chainer.initializers.LeCunUniform(scale=1.0, dtype=None)

Initializes array with a scaled uniform distribution.

Each element of the array is initialized by the value drawn independently from uniform distribution \([-s, s]\) where \(s = scale \times \sqrt{\frac{3}{fan_{in}}}\). Here \(fan_{in}\) is the number of input units.
