down ratio

[bruceyang2012]

If I want to change the down ratio from 4 to 1, where should I change the code?

You will need to modify the network files. Currently, DLA supports down ratio [2, 4, 8, 16] and other networks only support 4. You will need to design how to do upsample yourself. I haven't tried down ratio 1 for any networks, but have tried down ratio 2 for dla on pascal once. The result becomes worse (-2 mAP) than downsample 4, if not changing any other hyper-parameters. You are welcomed to share/ discuss your results for changing down ratio.

Is there any update on this thread for trying down ratio of 1?
