Abstract: Isolation Forest (IF) remains widely used for unsupervised anomaly detection in financial and cybersecurity applications, but its effectiveness is highly sensitive to the contamination ...

Abstract: In this paper, we propose an anomaly detection model based on Extended Isolation Forest and Denoising Autoencoder, which achieves unsupervised anomaly detection with good generalization ...

While most of the world’s 4,000 snake species pose little threat to humans, a handful of giants are powerful enough to take down deer, crocodiles, and even other top predators. From Indian and African ...
