Support Vector Machines (SVM) are believed to be as powerful as Artificial Neural Networks (ANN) in modeling complex problems while avoiding some of the drawbacks of the latter such as local minimæ or reliance on architecture. However, a question that remains to be answered is whether SVM users may expect improvements in the interpretability of their models, namely by using rule extraction meth...

The relative performances of different classifiers applied to the same data are typically analyzed using the Receiver Operator Characteristic framework (ROC). This paper proposes a further analysis by explaining the operation of classifiers using low-order Boolean rules to fit the predicted response surfaces using the Orthogonal Search Based Rule Extraction algorithm (OSRE). Four classifiers of...

Virtual campus environments are becoming a mainstream alternative to traditional distance higher education. The Internet medium they use allows the gathering of information on students’ usage behaviour. The knowledge extracted from this information can be fed back to the e-learning environment to ease teachers’ workload. In this context, two problems are addressed in the current study: finding ...

Rhenium is an important alloying agent in catalytic materials and superalloys, but the experimental and computational data on its binary alloys are sparse. Only 6 out of 28 Re transition-metal systems are reported as compound-forming. Fifteen are reported as phase-separating, and seven have high-temperature disordered σ or χ phases. Comprehensive high-throughput first-principles calculations pr...

Artificial neural networks is one of the most commonly used machine learning algorithms in medical applications. However, they are still not used in practice in the clinics partly due to their lack of explanatory capacity. We compare two case-based explanation methods to two trained physicians on analysis of electrocardiogram (ECG) data from patients with a suspected acute coronary syndrome (AC...
