Entropic One-Class Classifiers

2015 · IEEE Transactions on Neural Networks and Learning Systems

The one-class classification problem is a well-known research endeavor in pattern recognition. The problem is also known under different names, such as outlier and novelty/anomaly detection. The core of the problem consists in modeling and …

Concept Drift and Anomaly Detection in Graph Streams

2018 · IEEE Transactions on Neural Networks and Learning Systems

Graph representations offer powerful and intuitive ways to describe data in a multitude of application domains. Here, we consider stochastic processes generating graphs and propose a methodology for detecting changes in stationarity of such processes. …
