Thanks to the answer of @GZ0, the performance of this code snippet is now around 0.0344s on a GPU and around 0.2511s on a CPU. The implementation of @GZ0's algorithm is attached. Please do not hesitate to suggest any modifications to make the code snippet more pythonic :) import timeit import torch import argparse import numpy as np USE_CUDA = torch.cuda....

I think a different approach is needed to achieve a better performance. The current approach recomputes the Jaccard similarity from scratch for each possible threshold value. However, going from one threshold to the next, only a small fraction of prediction values change as well as the intersection and the union. Therefore a lot of unnecessary computation is ...
