New 'effective dimension' measure quantifies learning performance factors

Researchers have introduced the "effective dimension," a novel learning measure designed to quantify the impact of problem properties like constructive induction, noise filtering, and background knowledge on average-case learning performance. This new measure, which can be estimated empirically and makes average-case predictions, aims to be more widely applicable than the Vapnik-Chervonenkis (VC) dimension. The paper demonstrates the effective dimension's utility across various learning systems, including Backpropagation, and precisely predicts the benefits of feature construction systems like FRINGE, showing that these benefits diminish as target concept complexity increases.
