Better Guarantees for $k$-Means and Euclidean $k$-Median by Primal-Dual Algorithms
(Society for Industrial and Applied Mathematics, 2020-01-01)Clustering is a classic topic in optimization with $k$-means being one of the most fundamental such problems. In the absence of any restrictions on the input, the best-known algorithm for $k$-means in Euclidean space with ... -

Beyond Conjugacy for Chain Event Graph Model Selection
(Elsevier, 2024-07-20)Chain event graphs are a family of probabilistic graphical models that generalise Bayesian networks and have been successfully applied to a wide range of domains. Unlike Bayesian networks, these models can encode ... -
Beyond COVID-19: Network science and sustainable exit strategies
(IOP Publishers, 2020)On May $28^{th}$ and $29^{th}$, a two day workshop was held virtually, facilitated by the Beyond Center at ASU and Moogsoft Inc. The aim was to bring together leading scientists with an interest in Network Science and ... -
Beyond pairwise network similarity: exploring Mediation and Suppression between networks
(2021)Network similarity measures quantify how and when two networks are symmetrically related, including measures of statistical association such as pairwise distance or other correlation measures between networks or between ... -
Beyond the clustering coefficient: A topological analysis of node neighbourhoods in complex networks
(Elsevier, 2019)In Network Science node neighbourhoods, also called ego-centered networks have attracted large attention. In particular the clustering coefficient has been extensively used to measure their local cohesiveness. In this ... -

Bipartisanship Breakdown, Functional Networks, and Forensic Analysis in Spanish 2015 and 2016 National Elections.
(Hindawi, 2018-01-24)We present a social network and forensic analysis of the vote counts of Spanish national elections that took place in December 2015 and their sequel in June 2016. We initially consider the phenomenon of bipartisanship ... -
The black hole behind the cut
(Springer Nature, 2023-10-01)We study the analytic structure of the heavy-heavy-light-light holographic correlators in the supergravity approximation of the AdS3 × S 3/CFT2 duality. As an explicit example, we derive the correlator where the heavy ... -
Black hole collapse in the 1/c expansion
(2016-07-01)We present a first-principles CFT calculation corresponding to the spherical collapse of a shell of matter in three dimensional quantum gravity. In field theory terms, we describe the equilibration process, from early times ...
