A subspace method for large-scale trace ratio problems
G. Ferrandi, M. E. Hochstenbach, M. R. Oliveira
A subspace method is introduced to solve large-scale trace ratio problems. This approach is matrix-free, requiring only the action of the two matrices involved in the trace ratio.…

On the trace ratio method and Fisher's discriminant analysis for robust multigroup classification
Giulia Ferrandi, Igor V. Kravchenko, Michiel E. Hochstenbach +1
We compare two different linear dimensionality reduction strategies for the multigroup classification problem: the trace ratio method and Fisher's discriminant analysis. Recently,…
