研究方向
Investigate the LOCI implementation in pyod (likely in pyod/models/loci.py). Profile memory and time usage using Python profiling tools. Check if the algorithm can be vectorized or optimized. Review comments in the issue for maintainer suggestions (there are 3 comments and the issue is assigned).
