Successive Concave Sparsity Approximation for Compressed Sensing
Mohammadreza Malek-Mohammadi, Ali Koochakzadeh, Massoud Babaie-Zadeh +2
In this paper, based on a successively accuracy-increasing approximation of the norm, we propose a new algorithm for recovery of sparse vectors from underdetermined measur…
Upper Bounds on the Error of Sparse Vector and Low-Rank Matrix Recovery
Mohammadreza Malek-Mohammadi, Cristian R. Rojas, Magnus Jansson +1
Suppose that a solution to an underdetermined linear system is given. is approximately sparse…
Bayesian Learning for Low-Rank matrix reconstruction
Martin Sundin, Cristian R. Rojas, Magnus Jansson +1
We develop latent variable models for Bayesian learning based low-rank matrix completion and reconstruction from linear measurements. For under-determined systems, the developed me…
Ranging without time stamps exchanging
Mohammad Reza Gholami, Satyam Dwivedi, Magnus Jansson +1
We investigate the range estimate between two wireless nodes without time stamps exchanging. Considering practical aspects of oscillator clocks, we propose a new model for ranging…
Combined modeling of sparse and dense noise for improvement of Relevance Vector Machine
Martin Sundin, Saikat Chatterjee, Magnus Jansson
Using a Bayesian approach, we consider the problem of recovering sparse signals under additive sparse and dense noise. Typically, sparse noise models outliers, impulse bursts or da…
