Which algorithms support ‘Semi-supervised Novelty Detection’？

[hzf125521]

Hi everyone:
In 'outlier-detection-101'(https://pyod.readthedocs.io/en/latest/relevant_knowledge.html#outlier-detection-101), it said this package support 'Unsupervised Outlier Detection' and 'Semi-supervised Novelty Detection'.
I need 'Semi-supervised Novelty Detection', whose training data consists only of observations describing normal behavior, but l don't know which algorithm to choose.
I tried to find the answer from the examples, but the training data in the examples consists of both normal data and abnormal data.
