Severe Class Imbalance: Why Better Algorithms Aren't the Answer
This paper argues that severe class imbalance is not just an interesting technical challenge that improved learning algorithms will address, it is much more serious. To be useful, ...

The Problem of Fragile Feature Subset Preference in Feature Selection Methods and a Proposal of Algorithmic Workaround
Abstract—We point out a problem inherent in the optimization scheme of many popular feature selection methods. It follows from the implicit assumption that higher feature selecti...

Scheduling Algorithms with Bus Bandwidth Considerations for SMPs
The bus that connects processors to memory is known to be a major architectural bottleneck in SMPs. However, both software and scheduling policies for these systems generally focu...
