Why does it take so long to process

[pvnieo]

it's the time required to do the optimization,
feel free to suggest any modifications to make it faster!

The official code is about 0.5 seconds per image, but this code takes 9 seconds.

do you have access to the official code? or just the compiled version?
if it's the case, do you mind sharing it with me?

Hi, I amd also looking forward to some speed ups.

The code here seems to be implementing equation 8 in the LIME paper, which is not the sped-up solver and thus slow.

Some other implementations (that I wasn't able to fully understand) use some iterative solvers which seems to solve equation 19 in the paper.

Can you understand these codes?

Hi @YeolJ00

Thanks for the references, I'll take a look when I have time!

the url metioned in the paper can not be acessed
maybe this is the official demo?
