Outline of Final Research Achievements

We developed feature selection methods for small-sample, large-input problems. To speed up the block addition and block deletion (BABD) methods developed previously, we developed the iterative BABD that repeatedly iterates BABD and incremental BABD that applies BABD to a block of features divided in advance. To speed up training of support vector machines that are used for feature selection, we developed the SMO-NM method that combines the sequential minimal optimization technique and the Newton Method. We evaluated the validity of the proposed methods using benchmark data sets.
