I've not seen anything convincing that slide can approximate convolutional layers like at all without almost doing a full convolution at which point it is not competitive.
Can you link me to paper about recent (2021?) work or improvements with slide?
seems mostly about tuning the original idea instead of expanding its scope. But it's still a neat idea. I guess it could be possible to adpt many of the approximations used in the SLIDE idea to GPUs too though...
I thought SLIDE was optimized for classification with mind-boggingly sparse data. I.e. "choose the best label for this image out of those 1 mio choices".
