Abstract: Abstract Software quality is costly to achieve for large systems. Developers and testers need to investigate a large number of software modules to ensure software quality. This investigation is time consuming and formal models such as machine learning techniques are used to predict the fault-proneness of software modules to predict where faults are more probable. However, many modules are small in either implementation or design size and have low priority to investigate their quality. In this research, machine learners are used to classify the most complex parts of software. The less complex software modules are filtered out using two size measures: number of public parameters in a software construct and line of code (LOC) as a surrogate of implementation size. Modules at lowest 10, 20 and 30% of each measure are filtered out of the trained and tested data sets. The remaining modules are used to build four classifiers: Naïve Bayes, logistic regression, nearest neighbors and decision trees. The resulting classifiers were evaluated and compared against the original data. The classifiers based on NPM filtering were more consistent with the data without filtering than the LOC size measure.
