Clarification on the Meaning and Definition of MobileNetV3_BLOCK's Fourth Parameter in Ultralytics Source Code

[shiyanshilaoshu]

Hello, your work is really impressive, and I really like your experiments on the number of channels in the inverted bottleneck structure. Additionally, I would like to ask about the meaning of the fourth parameter (True or False) in the args of MobileNetV3BLOCK in the source code you provided（./ultralytics/cfg/cfg/leyolo.yaml）. Does it represent enabling the inductive bias of the convolutional layer? Could you please tell me where its detailed definition is in the code?

Hi! Thank you very much for your feedback. Indeed, the true/false statements are a mistake; I should have removed them. They're leftover from my research! I wanted to add a small spatial attention block, like in the mobilenetv3 and EfficientDet paper, with squeeze-and-excite at specific parts of LeYOLO, using a true or false statement where you wish to use it. However, I never found any interest in using SE or channel-attention, and the parameter is not used anymore in the block code. However, I let it stay that way to keep my research going while publishing LeYOLO; I might change everything to false and document the .yaml file better! The code is in ultralytics/nn/modules/block.py.
