Sharing weight in Caffe

[Dzung Nguyen]

How does one specify weight sharing in Caffe? Is it simply use the same param name, as in the siamese example?

[Viveka Kulharia]

Yes.

[Jan]

Yes, and this is the only real reason to give names to parameters. The names do not have any other use than sharing afaik.

But how to share weights in batch norm layer? and the var and means?

These cannot be shared in the regular sense of "shared weight" in Caffe since the mean and var are not learnable params updated by the solver but local state to each batch norm layer that are updated by the layer.
