Abstract

Automated approaches for parameter and algorithm selection greatly democratize fields such as machine learning, saving time and money as hiring experts can be prohibitively expensive. Unfortunately, anomaly detection is difficult to automate due to subjectivity and class imbalance. An anomaly detection system is presented that incorporates human-in-the-loop techniques and is dynamic, scalable, and able to work with non-annotated data. By focusing on meta-features of the input data, the system can intelligently choose the most promising anomaly detection methods. The system is agnostic to the medium of data; it only expects the data to be sequential in nature.
