tf.glorot_normal_initializer

tf.glorot_normal_initializer(
    seed=None,
    dtype=tf.float32
)

Defined in tensorflow/python/ops/init_ops.py.

The Glorot normal initializer, also called Xavier normal initializer.

It draws samples from a truncated normal distribution centered on 0 with stddev = sqrt(2 / (fan_in + fan_out)) where fan_in is the number of input units in the weight tensor and fan_out is the number of output units in the weight tensor.
