UW-Madison ECE Dissertation Award

Laura is very honored to receive the 2012 award for Best Dissertation from the University of Wisconsin, Madison ECE Department. The award even came with some cash, which Rob Nowak pointed out will buy a LOT of beer when we celebrate during the SILO meeting in June. Hope to see you there.

Thanks EECS 600 Students!

Laura wants to thank her students in EECS 600 for being so awesome and dedicated. A great first class to teach at Michigan!

EPA Air Sensors Meeting

Laura gave a plenary talk at the EPA Air Sensors meeting in Raleigh in March. There are lots of exciting opportunities for signal processing in air quality sensing!

IPAM Meeting

The IPAM meeting on Adaptive Data Analysis and Sparsity was a big success. Thank you to everyone who participated.

GRASTAcam

The GRASTAcam code is availabile for download here. This code uses OpenCV to run Grasta using the camera on your computer. It was written by Arthur Szlam (with makefile by Jia Xu, Thanks Jia!) in C using the Intel MKL library.

GRASTA

Grassmannian Robust Adaptive Subspace Tracking Algorithm (GRASTA), is an algorithm for subspace identification and tracking in the presence of corrupted and missing data. The algorithm is derived using the Augmented Lagrangian for an l1 cost function. See our page on GRASTA for code and a description of the algorithm.

GROUSE

Grassmannian Rank-One Update Subspace Estimation (GROUSE), is an online algorithm for subspace identification and tracking when data vectors are incomplete. See our page on GROUSE for details about the algorithm. GROUSE can be used for matrix completion; download grouse.m for the Matlab function and rungrouse.m to see how to run it.

Generating all rooted trees

Matlab code to enumerate all possible trees on n nodes: I wrote this awhile ago when I needed to enumerate all possible trees that could be formed by a set of n nodes. There are n^(n-1) such trees. This code uses the fact that there is a bijection between these trees and Prufer sequences. Here is tree_enumeration.m, which is a skeleton file for running code on all possible trees, and here is the function for generating the next tree, get_next_tree.m.

Compressed Sensing in Audio Signals

A demo for Compressed Sensing in Audio Signals can be found here, along with matlab code for the examples.

Blind Calibration

Blind Calibration examples and code can be found here.
