Data Representation using the Weyl Transform
Qiang Qiu, Andrew Thompson, Robert Calderbank +1
The Weyl transform is introduced as a rich framework for data representation. Transform coefficients are connected to the Walsh-Hadamard transform of multiscale autocorrelations, a…
Random Forests Can Hash
Qiang Qiu, Guillermo Sapiro, Alex Bronstein
Hash codes are a very efficient data representation needed to be able to cope with the ever growing amounts of data. We introduce a random forest semantic hashing scheme with infor…
A Bi-clustering Framework for Consensus Problems
Mariano Tepper, Guillermo Sapiro
We consider grouping as a general characterization for problems such as clustering, community detection in networks, and multiple parametric model estimation. We are interested in…
Low-Cost Compressive Sensing for Color Video and Depth
Xin Yuan, Patrick Llull, Xuejun Liao +4
A simple and inexpensive (low-power and low-bandwidth) modification is made to a conventional off-the-shelf color video camera, from which we recover {multiple} color frames for ea…
