Whence to Learn? Transferring Knowledge in Configurable Systems Using BEETLE

Krishna, R., Nair, V., Jamshidi, P., & Menzies, T. (2020, March 30). IEEE Transactions on Software Engineering, Vol. 47, pp. 2956–2972.

By: R. Krishna *, V. Nair n, P. Jamshidi * & T. Menzies n 

author keywords: Performance optimization; SBSE; transfer learning; bellwether
topics (OpenAlex): Software Engineering Research; Software System Performance and Reliability; Software Testing and Debugging Techniques
TL;DR: This paper proposes a novel transfer learning framework called BEETLE, which is a “bellwether”-based transfer learner that focuses on identifying and learning from the most relevant source from amongst the old data. (via Semantic Scholar)

Data-driven search-based software engineering

Nair, V., Agrawal, A., Chen, J., Fu, W., Mathew, G., Menzies, T., … Yu, Z. (2018, May 28). 2018 IEEE/ACM 15TH INTERNATIONAL CONFERENCE ON MINING SOFTWARE REPOSITORIES (MSR), pp. 341–352.

By: V. Nair n, A. Agrawal n, J. Chen n, W. Fu n, G. Mathew n, T. Menzies n , L. Minku*, M. Wagner*, Z. Yu n 

topics (OpenAlex): Software Engineering Research; Software Testing and Debugging Techniques; Software Reliability and Analysis Research
TL;DR: It is argued that combining these two fields is useful for situations which require learning from a large data source or when optimizers need to know the lay of the land to find better solutions, faster. (via Semantic Scholar)

2018 article

Is one hyperparameter optimizer enough?

Tu, H., & Nair, V. (2018, November 5).

By: H. Tu n & V. Nair n

author keywords: Defect Prediction; SBSE; Hyperparameter Tuning
topics (OpenAlex): Software Engineering Research; Machine Learning and Data Classification; Software Reliability and Analysis Research
TL;DR: It is concluded that hyperparameter optimization is more nuanced than previously believed and, while such optimization can certainly lead to large improvements in the performance of classifiers used in software analytics, it remains to be seen which specific optimizers should be applied to a new dataset.

Micky: A Cheaper Alternative for Selecting Cloud Instances

Hsu, C.-J., Nair, V., Menzies, T., & Freeh, V. (2018, July 1). PROCEEDINGS 2018 IEEE 11TH INTERNATIONAL CONFERENCE ON CLOUD COMPUTING (CLOUD), pp. 409–416.

By: C. Hsu n, V. Nair n, T. Menzies n  & V. Freeh n

topics (OpenAlex): Stochastic Gradient Optimization Techniques; Cloud Computing and Resource Management; Advanced Bandit Algorithms Research
TL;DR: A collective-optimizer is created, MICKY, that reformulates the task of finding the near-optimal cloud configuration as a multi-armed bandit problem and can achieve on average 8.6 times reduction in measurement cost as compared to the state-of-the-art method while finding near-Optimal solutions.

“Sampling” as a Baseline Optimizer for Search-Based Software Engineering

Chen, J., Nair, V., Krishna, R., & Menzies, T. (2018, January 8). IEEE Transactions on Software Engineering, Vol. 45, pp. 597–614.

By: J. Chen n, V. Nair n, R. Krishna  n & T. Menzies n 

author keywords: Search-based SE; sampling; evolutionary algorithms
topics (OpenAlex): Software Engineering Research; Software Engineering Techniques and Practices; Advanced Software Engineering Methodologies
TL;DR: This paper compares Sway versus state-of-the-art search-based SE tools using seven models: five software product line models; and two other software process control models (concerned with project management, effort estimation, and selection of requirements) during incremental agile development.

2017 article

Beyond evolutionary algorithms for search-based software engineering

Chen, J., Nair, V., & Menzies, T. (2017, September 6). Information and Software Technology, Vol. 95, pp. 281–294.

By: J. Chen n, V. Nair n & T. Menzies n 

topics (OpenAlex): Evolutionary Algorithms and Applications; Advanced Multi-Objective Optimization Algorithms; Software Engineering Research
TL;DR: This work builds a very large initial population which is then culled using a recursive bi-clustering chop approach, and evaluates this approach on multiple SE models, unconstrained as well as constrained, and compare its performance with standard evolutionary algorithms.

Using bad learners to find good configurations

Nair, V., Menzies, T., Siegmund, N., & Apel, S. (2017, August 2). ESEC/FSE 2017: PROCEEDINGS OF THE 2017 11TH JOINT MEETING ON FOUNDATIONS OF SOFTWARE ENGINEERING, pp. 257–267.

By: V. Nair n, T. Menzies n , N. Siegmund * & S. Apel *

author keywords: Performance Prediction; SBSE; Sampling; Rank-based method
topics (OpenAlex): Software System Performance and Reliability; Software Engineering Research; Software Reliability and Analysis Research
TL;DR: This paper demonstrates that performance models that are cheap to learn but inaccurate can still be used rank configurations and hence find the optimal configuration and significantly reduce the cost as well as the time required to build performance models. (via Semantic Scholar)
