11/7/2019 · Create a new variable with value initial_value. Parameters explained . initial_value: the initial value of new variable. trainable: make this variable can be traind by model, if you set False, the value of varaible can not be modified when minimizing the loss.. name: variable name, you should set a name for variable in order to you can get the variable value by its name.
One has to create the variable set only once per whole training (and testing) set. The goal of variable scopes is to allow for modularization of subsets of parameters, such as those belonging to layers (e.g. when architecture of a layer is repeated, the same names can be used within each layer scope).. In your example you create parameters only in the model function.
