Vector Approximate Message Passing

open access: yesIEEE Transactions on Information Theory, 2019
The standard linear regression (SLR) problem is to recover a vector $\mathrm {x}^{0}$ from noisy linear observations $\mathrm {y}=\mathrm {Ax}^{0}+\mathrm {w}$ . The approximate message passing (AMP) algorithm proposed by Donoho, Maleki, and Montanari

Real-Time Action Recognition with Enhanced Motion Vector CNNs [PDF]

open access: yesComputer Vision and Pattern Recognition, 2016
The deep two-stream architecture [23] exhibited excellent performance on video based action recognition. The most computationally expensive step in this approach comes from the calculation of optical flow which prevents it to be real-time.

Selecting training sets for support vector machines: a review

open access: yesArtificial Intelligence Review, 2019
Support vector machines (SVMs) are a supervised classifier successfully applied in a plethora of real-life applications. However, they suffer from the important shortcomings of their high time and memory training complexities, which depend on the ...

Public-key cryptosystems from the worst-case shortest vector problem: extended abstract

open access: yesSymposium on the Theory of Computing, 2009
We construct public-key cryptosystems that are secure assuming theworst-case hardness of approximating the minimum distance on n-dimensional lattices to within small Poly(n) factors.

On stability conditions of vector \(l_\infty\)-extreme combinatorial problem with Pareto principle of optimality

open access: yesJournal of Numerical Analysis and Approximation Theory, 2003
We consider the multicriteria problem of combinatorial optimization with partial criteria of the kind MINMAX MODUL. The parameters of criteria are subject to "small" independent perturbations.
