dysample channel

[nzomi]

Hi, I noticed that the dysample can be used for same channel transformation.
e.g., from (1, 64, 256, 256) → (1, 64, 256scale, 256scale)

If I want to change the output channel while using dysample, I think I can only follow these steps:
e.g., from channel 64 to channel 32

1. Apply dysample to change spatial resolution: (1, 64, 256, 256) → (1, 64, 256scale, 256scale)
2. Add a convolution layer to adjust the channel: (1, 64, 256scale, 256scale) → (1, 32, 256scale, 256scale)
   or do the channel reduction firstly then applying dysample.

Is there any method to adjust the ouput channel without using more convolution layers?

Hi. There is no operation for changing channel numbers in DySample. I recommend to first use DySample and then use a linear/1x1conv layer to reduce the channel number.
