WebFeb 18, 2024 · DBSCAN has a worst case memory complexity O(n^2), which for 180000 samples corresponds to a little more than 259GB. This worst case situation can happen if eps is too large or min_samples too low, ending with all points being in a same cluster. However it does not seem to be the only issue here.
