... useful classification accuracies when the negative class is well characterized. The advantage of one class methods is that it eliminates guessing at the optimal features for the negative class when ... a negative class where the basis for defining this class is not clear. The only required input for this tool is the miRNA sequences from a specific g...

Since the selection environment that maximises ∆G is the same environment that maximises ... increasing distance from the intercept, being 5% lower at 1 SD from the intercept. The Bulmer effect was accounted for by an iterative reduction of the ge...

... example from a temporally ordered sequence is sent to the learner, which returns the prediction. The error incurred on this example is recorded, and the true output is only then sent to the learner which ... horizon- tal axis indexes the position in the data stream. The vertical axis shows the class proportions at each position, averaged over a window containing 7%...
