Batch size

[neuralchen]

Can i set a larger batch size for example 16? I learn that the default batch size is 1. Actually, i have some questiones about the kernel, if i input an batch(B) of different images and correponding guided features into the pacconv. Different guided features will produce different kernels. There are multiple different kernels in a batch that will increase the complexity of the forward calculation. How do you deal with this kind of problem?

Depending on the size of your image, network, gpu mem, etc., you can definitely try higher batch size.

A major advantage of our operation is exactly that -- different kernels for different images (and locations). Computation-wise there isn't really much overhead compared to a naive conv implementation relying on im2col, however admittedly we are not able to utilize as much optimization and is somewhat memory-heavy.
