A subspace method for large-scale trace ratio problems

Autor: Ferrandi, G., Hochstenbach, M. E., Oliveira, M. R.

We present a subspace method to solve large-scale trace ratio problems. This method is matrix-free, only needing the action of the two matrices in the trace ratio. At each iteration, a smaller trace ratio problem is addressed in the search subspace.

In this paper we consider the problem of placing proxy caches in a network to get a better performance of the net. We develop a heuristic method to decide in which nodes of the network proxies should be installed and what the sizes of these caches sh
