Deep iForest

This repository is the source code of the paper "Deep Isolation Forest for Anomaly Detection" published in TKDE (April 2023). (see full paper at https://arxiv.org/abs/2206.06602 or https://ieeexplore.ieee.org/document/10108034/ )

How to use?

DIF provides easy APIs like the sklearn style. We first instantiate the model class by giving the parameters
then, the instantiated model can be used to fit and predict data

from algorithms.dif import DIF
model_configs = {'n_ensemble':50, 'n_estimators':6}
model = DIF(**model_configs)
model.fit(X_train)
score = model.decision_function(X_test)

💥Note:

• DIF is also included in our DeepOD python library. Please see https://github.com/xuhongzuo/DeepOD
• Please also see the Zhihu blog (in Chinese) https://zhuanlan.zhihu.com/p/625557221
