I have trouble understanding the masks in PixelCNN 1.
Here for A, each channel is connected to prior channels. For B, channels are also connected to themselves. My problem is in first layer when I go from 3 channels to number of filters. Let's say I have 128 filters, how is the mask then implemented? What I implemented so far with the assumption that there is same number of channels in each layer is:
H = KERNEL_SIZE[0]
W = KERNEL_SIZE[1]
N = OUT_CHANNEL
M = IN_CHANNEL
# implement context mask
mask = np.zeros((N, M, H, W))
mask[:,:,:(H//2)] = 1
mask[:,:,(H//2),range((W//2))] = 1
# implement channel mask
if mask_type == 'A':
mask[np.triu_indices(N, k=0, m=M)] = 0
elif mask_type == 'B':
mask[np.triu_indices(N, k=1, m=M)] = 0
