Dynamic size weights for BCECriterion?

[hiwonjoon]

Hello,

I am try to use BCECriterion with weights parameter, but the function interface seems weird for me.
Is any reason we keep weights vector instead of just single weight for true label? I can't figure out what does it mean since we generally do not discriminate data for the index on a mini-batch.

The real problem is, at the end of the training or validation, The size of batch become # of items % batchSize, which is not equal to batchSize.

Do I understand correctly on this issue? Is there any way to mitigate this problem?

Thanks.
