How can I conduct channel pruning only?

[zlheos]

first, I really appreciated for your help!
Then I have some quesqions
How can i set single channel pruning?
how much is channel prunning accerate ration ?
why channel_pruning_VGG-16_3C4x.caffemodel is so big ?

To use only channel pruning, u need modify the function r3 in net.py. for acceleration ratio, look at paper and code.
Because it's a 40+ layers network.

sorry to trouble you !
I don't know how to modify r3 for single channel prunning ?
thank you very much!

We currently are not planning to release other parts of code.

Sorry to trouble you !
in R3 function
why don't prunning conv1_1 ?
and
I see pooldic = ['conv1_2', 'conv2_2'] ] , why no 'conv3_3' and others ?
I really appreciated for your help!

[ethanhe42]

• conv1_1 contributes little computation.
• VH decompose degrades performance when decomposing conv3_3 and later pre-pooling-conv

thank you !
if only CR , how much should we set for c_ratio parameter ?
and how much should we set for very layer compression ration ?

@zlheos hello. Do you know how to use @yihui-he's code to perform single-layer pruning?
