the limit of btn

[ct-wei]

The constraint limit the btn in

lightweight-neural-architecture-search/tinynas/spaces/mutator/super_res_k1kx_mutator.py

Line 72 in 6bf4d69

new_btn = min(new_out, structure_info_next['btn'])

lightweight-neural-architecture-search/tinynas/spaces/mutator/super_res_k1kx_mutator.py

Line 82 in 6bf4d69

new_btn = min(structure_info['out'], new_btn)

but this
https://github.com/tinyvision/DAMO-YOLO/blob/master/damo/base_models/backbones/nas_backbones/tinynas_nano_middle.txt
seems to have broken the limit
May I ask why? thanks

That's a good question. For small or mobile models, particularly those with depthwise search space, we have observed that the limitation on btn may constrain the final accuracy. The similar observation can be found in mobilenetv3 paper.
