# Glorot Uniform

(scalar or matrix or initializer, defaults to init_glorot_uniform()) - initial value of weights W. A Keras tensor is a tensor object from the underlying backend (Theano, TensorFlow or CNTK), which we augment with certain attributes that allow us to build a Keras model just by knowing the inputs and outputs of the model. class DeviceCountEntry. Here are the examples of the python api keras. In this post you will discover how you can use deep learning models. By using Xavier initialization, we make sure that the weights are not too small but not too big to propagate accurately the signals. Showing 1-2 of 2 messages. models import Model from keras. 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. It may be useful for you to design small experiments with a smaller subset of your data that will complete in a reasonable time.

The Glorot initializer independently samples from a uniform distribution with zero mean and variance 2/(InputSize + numOut), where numOut = 8*NumHiddenUnits. Activations. Ok, the code is slightly obfuscated as you instantiate the layers and "call" them later, that is fine. This is suitable for most CNNs. If you wrap your load_model with the below CustomObjectScope method, it would work fine. Xavier 초기화(glorot_uniform, glorot_normal): 케라스에서는 glorot이라는 이름으로 되어있는데, 일반적으로는 Xavier Initialization이라고 알려져 있다. The resulting values are drawn from a truncated normal distribution and are always within two standard deviations from the mean (which is 0). The following are code examples for showing how to use keras. initializer_glorot_uniform.
