Group Model Selection Using Marginal Correlations: The Good, the Bad and the Ugly
Waheed U. Bajwa, Dustin G. Mixon
Group model selection is the problem of determining a small subset of groups of predictors (e.g., the expression data of genes) that are responsible for majority of the variation i…
Level set estimation from projection measurements: Performance guarantees and fast computation
Kalyani Krishnamurthy, Waheed U. Bajwa, Rebecca Willett
Estimation of the level set of a function (i.e., regions where the function exceeds some value) is an important problem with applications in digital elevation mapping, medical imag…
Toward Resource-Optimal Consensus over the Wireless Medium
Matthew Nokleby, Waheed U. Bajwa, Robert Calderbank +1
We carry out a comprehensive study of the resource cost of averaging consensus in wireless networks. Most previous approaches suppose a graphical network, which abstracts away cruc…
A Constrained Random Demodulator for Sub-Nyquist Sampling
Andrew Harms, Waheed U. Bajwa, Robert Calderbank
This paper presents a significant modification to the Random Demodulator (RD) of Tropp et al. for sub-Nyquist sampling of frequency-sparse signals. The modification, termed constra…
