TensorFlow colletion organize different categories of objects with collections. Tf. The Graphkeys contains the names of all the default collections.
Collection provides a "Zecundi" idea: In any position, can create objects at any level, into the corresponding collection, after the creation, unified from a collection to take out a class of variables, apply the corresponding operation.
For example, TF. Optimizer only optimizes the variables i

the default value is taken, slim will update the mean and variance after the current batch is completed, which will have the problem that the mean and variance of the current batch data is always slow, resulting in poor performance of the model being trained. Therefore, it is generally necessary to set this value to none so that when slim batch processing, the mean and variance are updated immediately, and the batch process uses the latest mean and variance.
In addition, whether to update all t
