How to Better Distinguish Security Bug Reports (Using Dual Hyperparameter Optimization)

Shu, R., Xia, T., Chen, J., Williams, L., & Menzies, T. (2021, April 5). Empirical Software Engineering, Vol. 26.

By: R. Shu n, T. Xia n, J. Chen n, L. Williams n & T. Menzies n 

author keywords: Hyperparameter Optimization; Data pre-processing; Security bug report
topics (OpenAlex): Software Engineering Research; Software Testing and Debugging Techniques; Machine Learning and Data Classification
TL;DR: The SWIFT’s dual optimization of both pre-processor and learner is more useful than optimizing each of them individually, and this approach can quickly optimize models that achieve better recalls than the prior state-of-the-art. (via Semantic Scholar)

Omni: automated ensemble with unexpected models against adversarial evasion attack

Shu, R., Xia, T., Williams, L., & Menzies, T. (2021, November 30). Empirical Software Engineering, Vol. 27.

By: R. Shu n, T. Xia n, L. Williams n & T. Menzies n 

author keywords: Hyperparameter optimization; Ensemble defense; Adversarial evasion attack
topics (OpenAlex): Adversarial Robustness in Machine Learning; Advanced Malware Detection Techniques; Network Security and Intrusion Detection
TL;DR: Omni is a promising approach as a defense strategy against adversarial attacks when compared with other baseline treatments, and it is suggested to create ensemble with unexpected models that are distant from the attacker’s expected model through methods such as hyperparameter optimization.
