One-class classification – From theory to practice: A case-study in radioactive threat detection

作者：

Highlights：

• Summarize and extend our previous work on gamma-ray spectra classification;

• Explore the problem from the perspective of one-class within-class imbalance;

• Demonstrate how within-class imbalance impacts one-class classifiers; and

• Demonstrate solutions to one-class within-class imbalance in our domain
