Structured Prediction Models via the Matrix-Tree Theorem
This paper provides an algorithmic framework for learning statistical models involving directed spanning trees, or equivalently non-projective dependency structures. We show how p...

Optimality of Diagonalization of Multicarrier Multi-Hop Linear Non-Regenerative MIMO Relays
Abstract—In this paper, a multicarrier multi-hop multipleinput multiple-output (MIMO) relay system is investigated. A linear non-regenerative strategy is applied at each relay no...

Dual Transform Domain Echo Canceller for Discrete Multitone Systems
Abstract--In communication systems where full-duplex transmission is required, digital echo cancellers are employed to cancel echo by means of adaptive filtering. In order to reduc...

Additive Preconditioning for Matrix Computations
Versus the customary preconditioners, our weakly random ones are generated more readily and for a much larger class of input matrices. Furthermore our preconditioners have a wider...
