@authman Hi, I don't think that is what they used. I actually loaded up their released weights using their deploy prototxt and inspected the "ignored layers" output by caffe.

Apparently it was a conv/bn/relu/dropout block (the conv4_24
s) followed by a single conv (conv6_1
) in the auxiliary branch. Would that have made the difference between their reported result and the "meh" results you and I got? Not likely.
Personally I think the key to achieving their stellar accuracy is in finetuning the BN parameters on VOC across multiple GPUs. That is also confirmed by deeplab-v3 which did the BN trick and obtained almost the same accuracy as PSPNet.

I've tried with {ProjectionConv, BN, Relu, Dropout, Conv2d->NumClasses} as an aux branch. The results were 'meh'.

@qizhuli: do you know where can i get deeplabv3 source code? I did not find it. Thanks

@mjohn123 I don't think they have released it yet.
