What is the current best replacement for ResNet? (Focus on real-time application)

[timothylimyl]

It seems that a lot of repository out there is still using ResNet-18 and ResNet-50 as their backbone for downstream tasks such as object detection, segmentation and even classification. A lot of application performance could potentially be improved upon a swap of the vision backbone.

I am wondering what are the new backbones that can replace ResNet (beat it in terms of speed, accuracy and size)? Granted, I know that ResNet as a basis of design has led to many variants of it, but what variants or non-variants of resnet are your "go-to"?

Note that this is a comparison to be made for the ResNet series which is not in the realm of hundred million or billions parameters

Vote for regnet

Do you usually just pick from the regnet series? do you see great improvement in terms of accuracy given the same inference speed & size as something like resnet-18 (or an improved variant)?
