PlainMaskedConv2d does not handle connections between color channels
Hi there, I am trying to get the simple PixelCNN model working on CIFAR10, I took a look at your implementation here https://github.com/pbloem/pixel-models/blob/master/layers.py#L8-L32, and it looks like the masks are only on pixels, but there are no masks among RGB values, is this correct?
Hi, as far as I remember, the plain version you link to doesn't have connections between color values. This means it predicts each color independently from what it predicts for the other colors. This makes it a much simpler in implementation, but much less powerful than a model that conditions each color on the previous one.
The MaskedConv2d and its two conditional versions do this, but they're a bit more complicated as a result.
