Blocked algorithms for the reduction to Hessenberg-triangular form revisited
Springer (2008-09)We present two variants of Moler and Stewart’s algorithm for reducing a matrix pair to Hessenberg-triangular (HT) form with increased data locality in the access to the matrices. In one of these variants, a careful ... -
Combining Multiple Classifiers with Dynamic Weighted Voting
Springer Berlin Heidelberg (2009)When a multiple classifier system is employed, one of the most popular methods to accomplish the classifier fusion is the simple majority voting. However, when the performance of the ensemble members is not uniform, the ...
