GlorotUniformInitializer

Glorot uniform initializer, also called the Xavier uniform initializer..

This initializer draws samples from a uniform distribution within [-limit, limit], where limit is equal to sqrt(6 / (fanIn + fanOut)), where fanIn is the number of input units in the weight tensor and fanOut is the number of output units in the weight tensor.
