In this paper, we introduce a new approach to evaluate and visualize the classifier performance in two-class imbalanced domains. This method defines a two-dimensional space by combining the geometric mean of class accuracies and a new metric that gives an indication of how balanced they are. A given point in this space represents a certain trade-off between those two measures, which will be exp...

Coordinate measuring systems (CMSs) determine dimensional (length-based) characteristics of mechanical parts by analyzing 3-dimensional point data acquired on part surfaces. Data analysis software can contribute significantly to the total measurement error of a CMS. Factors affecting software performance include the choice of analysis method, the quality of software implementation, and characte...
