Evaluation of the branch and bound algorithm for feature selection

…, S Uchimura, Y Matsuura, T Kanaoka, S Tomita - Pattern Recognition …, 1990 - Elsevier
Narendra and Fukunaga show that the branch and bound algorithm guarantees the optimal
feature subset without evaluating all possible feature subsets, if the criterion function used …

On the behavior of artificial neural network classifiers in high-dimensional spaces

…, S Uchimura, S Tomita - IEEE Transactions on …, 1996 - ieeexplore.ieee.org
It is widely believed in the pattern recognition field that when a fixed number of training
samples is used to design a classifier, the generalization error of the classifier tends to increase …
