-Since 2017, PyOD has been successfully used in various academic researches [4, 8] and commercial products.
-Unlike existing libraries, PyOD provides:
-
-- **Unified APIs** across various anomaly detection algorithms for easy use.
-- **Advanced functions**, e.g., **Neural Networks/Deep Learning Models** and **Outlier Ensemble Frameworks**.
+- **Unified APIs, detailed documentation and interactive examples** across various anomaly detection algorithms for short learning curve.
+- **Advanced anomaly detection models**, e.g., **Neural Networks/Deep Learning** and **Outlier Ensembles**.
 - **Optimized performance with JIT compilation and parallelization**, when the condition allows.
-- **Compatibility with both Python 2 and 3**. All implemented algorithms are also **scikit-learn compatible**.
-- **Detailed API Reference, Interactive Examples in Jupyter Notebooks** for better reliability.
