描述

Is it possible to add DBSCAN based methods (https://en.wikipedia.org/wiki/DBSCAN#Extensions) for anomaly detection?

The normal DBSCAN/OPTICS in sklearn don't support a predict method as such but the hdbscan library supports one.

研究方向
To implement DBSCAN based methods, study the hdbscan library's predict functionality compared to sklearn's DBSCAN. Integrate the algorithm into pyod by adding a new detector class following existing conventions, inheriting from BaseDetector, and implementing fit and predict methods. Review pyod/models for structure and test with standard outlier detection datasets.
