Polynomial expansion detector for uniform linear arrays
In this paper, we design a low complexity linear MMSE decoder to recover the signal transmitted by M mobile users to a base station equipped with N receiving antennas, arranged as...

Word Alignment via Submodular Maximization over Matroids
We cast the word alignment problem as maximizing a submodular function under matroid constraints. Our framework is able to express complex interactions between alignment component...

An Information Theoretic Representation of Agent Dynamics as Set Intersections
We represent agents as sets of strings. Each string encodes a potential interaction with another agent or environment. We represent the total set of dynamics between two agents as ...

Nominal Schemas for Integrating Rules and Description Logics
We propose an extension of SROIQ with nominal schemas which can be used like “variable nominal concepts” within axioms. This feature allows us to express arbitrary DL-safe rule...
