Hyperparameter Optimization for Effort Estimation

2018 · arXiv (Cornell University)

Software analytics has been widely used in software engineering for many tasks such as generating effort estimates for software projects. One of the "black arts" of software analytics is tuning the parameters controlling a data …

"Sampling"' as a Baseline Optimizer for Search-based Software Engineering

2016 · arXiv (Cornell University)

Increasingly, Software Engineering (SE) researchers use search-based optimization techniques to solve SE problems with multiple conflicting objectives. These techniques often apply CPU-intensive evolutionary algorithms to explore generations of mutations to a population of candidate solutions. …
