Webb1 juli 2024 · The decision tree (DT) [25,26] algorithm is also a supervised classification method based on spatial data mining and knowledge discovery. Prior knowledge can be used in supervised classification to select training samples, and the classification accuracies can be improved by repeatedly testing training samples. Webb13 jan. 2024 · This approach will further optimize the query to O (log^2 N) time (since it's one tree operation now), giving the resulting complexity of O ( (N + Q)log^2 N)) both time and space. Not sure this solution is fast enough for both Q and N up to 10^5, but it may probably be further optimized.
