A practical, fast method for solving sum-of-squares problems for very large polynomials

Autor: Keren, Daniel, Osadchy, Margarita, Poranne, Roi

Sum of squares (SOS) optimization is a powerful technique for solving problems where the positivity of a polynomials must be enforced. The common approach to solve an SOS problem is by relaxation to a Semidefinite Program (SDP). The main advantage of

Geometric Covering using Random Fields

Autor: Goncalves, Felipe, Keren, Daniel, Shahar, Amit, Yehuda, Gal

A set of vectors $S \subseteq \mathbb{R}^d$ is $(k_1,\varepsilon)$-clusterable if there are $k_1$ balls of radius $\varepsilon$ that cover $S$. A set of vectors $S \subseteq \mathbb{R}^d$ is $(k_2,\delta)$-far from being clusterable if there are at l

The two critical temperatures conundrum in La$_{1.83}$Sr$_{0.17}$CuO$_4$

Autor: Abhisek Samanta, Itay Mangel, Amit Keren, Daniel P. Arovas, Assa Auerbach

Publikováno v: SciPost Physics, Vol 16, Iss 6, p 148 (2024)

The in-plane and out-of-plane superconducting stiffness of ${\rm La}^{\vphantom{\dagger}}_{1.83}{\rm Sr}^{\vphantom{\dagger}}_{0.17}{\rm CuO}^{\vphantom{\dagger}}_4$ rings appear to vanish at different transition temperatures, which contradicts therm

Adaptive Communication Bounds for Distributed Online Learning

Autor: Kamp, Michael, Boley, Mario, Mock, Michael, Keren, Daniel, Schuster, Assaf, Sharfman, Izchak

Publikováno v: Proceedings of the 7th NIPS Workshop on Optimization for Machine Learning, 2014

We consider distributed online learning protocols that control the exchange of information between local learners in a round-based learning scenario. The learning performance of such a protocol is intuitively optimal if approximately the same loss is
