Learning and inference algorithms for partially observed structured switching vector autoregressive models
We present learning and inference algorithms for a versatile class of partially observed vector autoregressive (VAR) models for multivariate time-series data. VAR models can captu...

Content preference estimation in online social networks: Message passing versus sparse reconstruction on graphs
We design two different strategies for computing the unknown content preferences in an online social network based on a small set of nodes in the corresponding social graph for wh...

MIMO radar for direction finding with exploitation of time-frequency representations
In this paper we consider the exploitation of spatial timefrequency distribution (STFD) in multiple-input multipleoutput (MIMO) radar systems. STFD has been found useful in solvin...

Interference alignment in single-beam MIMO networks via homotopy continuation
In this paper we consider the application of a homotopy-continuation based method for finding interference alignment (IA) solutions for the deterministic K-user multiple-input mu...
