glorot uniform initializer

Summary

The Glorot uniform initializer, also known as Xavier uniform initializer, draws samples from a uniform distribution within , where limit is sqrt(6 / (fan_in + fan_out)). 1 This limit is based on the number of nodes in the network, referred to as the "fan-in" and the "fan-out". 2 Therefore, Glorot uniform initialization uses limits that are based on the number of nodes in the network: sqrt( 6 / (nin + nout)). 2

Summary It draws samples from a uniform distribution within -limit, limit where limit is sqrt(6 / (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.

Summary . These are sometimes called the "fan-in" and the "fan-out". In short, instead of using fixed limits like -0.01 and +0.01, Glorot uniform initialization uses limits that are based on the number of nodes in the network: sqrt( 6 / (nin + nout)).
