Pairwise_distances sklearn
WebJan 10, 2024 · cdist vs. euclidean_distances. Difference in implementation can be a reason for better performance of Sklearn package, since it uses vectorisation trick for computing the distances which is more efficient. Meanwhile, after looking at the source code for cdist implementation, SciPy uses double loop. Method 2: single for loop
