2019 International Journal of Modern Education and Computer Science  
Apart from software attributes, for example, different alternative software modules, self-adaptation decisions depend on environmental attributes, for example, service rate, bandwidth etc.  ...  The environmental attributes are provided as a constraint to an optimization problem which results in an optimal software attribute selection.  ...  It takes metrics and software variants as inputs and provides training data set for each of the metrics.

A Comparative Study of Threshold-Based Feature Selection Techniques

Huanjing Wang, Taghi M. Khoshgoftaar, Jason Van Hulse
2010 2010 IEEE International Conference on Granular Computing  
Given high-dimensional software measurement data, researchers and practitioners often use feature (metric) selection techniques to improve the performance of software quality classification models.  ...  Moreover, performances of the software quality models either improve or remain unchanged despite the removal of over 96% of the software metrics (attributes).  ...  The default decision threshold is often not optimal, especially when the class is imbalanced. Therefore, we propose the use of performance metrics which allow for finding the optimal threshold.  ...
