An Alternative to EM for Gaussian Mixture Models: Batch and Stochastic Riemannian Optimization | We consider maximum likelihood estimation for Gaussian Mixture Models (Gmms).
This task is almost invariably solved (in theory and practice) via the

The Coprime Quantum Chain | In this paper we introduce and study the coprime quantum chain, i.e. a

Inverse cascades and resonant triads in rotating and stratified turbulence | Kraichnan seminal ideas on inverse cascades yielded new tools to study common

Spectral Mixture Kernels for Multi-Output Gaussian Processes | Early approaches to multiple-output Gaussian processes (MOGPs) relied on
linear combinations of independent, latent, single-output Gaussian processes
(GPs). This resulted in cross-covariance functions with limited parametric
interpretation, thus conflicting with the ability of single-output GPs to
understand lengthsc... | 0 | 0 | 0 | 1 | 0 | 0 |

Manton's five vortex equations from self-duality | We demonstrate that the five vortex equations recently introduced by Manton
ariseas symmetry reductions of the anti-self-dual Yang--Mills equations in four
dimensions. In particular the Jackiw--Pi vortex and the Ambj\o rn--Olesen
vortex correspond to the gauge group $SU(1, 1)$, and respectively the Euclidean

Deep Style Match for Complementary Recommendation | Humans develop a common sense of style compatibility between items based on

paper. The basic a... | 1 | 0 | 0 | 0 | 0 | 0 |
SpectralLeader: Online Spectral Learning for Single Topic Models | We study the problem of learning a latent variable model from a stream of
data. Latent variable models are popular in practice because they can explain
observed data in terms of unobserved concepts. These models have been
traditionally studied in the offline setting. In the online setting, on the
other hand, the onli... | 1 | 0 | 0 | 1 | 0 | 0 |

Tameness from two successive good frames | We show, assuming a mild set-theoretic hypothesis, that if an abstract

cardinality $\lambda^+$, then orbital types over models of cardinality

Detection and Characterization of Illegal Marketing and Promotion of Prescription Drugs on Twitter | Illicit online pharmacies allow the purchase of prescription drugs online

First Hochschild cohomology group and stable equivalence classification of Morita type of some tame symmetric algebras | We use the dimension and the Lie algebra structure of the first Hochschild

When is a Convolutional Filter Easy To Learn? | We analyze the convergence of (stochastic) gradient descent algorithm for

Robots as Powerful Allies for the Study of Embodied Cognition from the Bottom Up | A large body of compelling evidence has been accumulated demonstrating that
embodiment - the agent's physical setup, including its shape, materials,
sensors and actuators - is constitutive for any form of cognition and as a

Conductance distribution in the magnetic field | Using a modification of the Shapiro scaling approach, we derive the

Linear Convergence of An Iterative Phase Retrieval Algorithm with Data Reuse | Phase retrieval has been an attractive but difficult problem rising from

Representing smooth functions as compositions of near-identity functions with implications for deep network optimization | We show that any smooth bi-Lipschitz $h$ can be represented exactly as a
composition $h_m \circ ... \circ h_1$ of functions $h_1,...,h_m$ that are close
to the identity in the sense that each $\left(h_i-\mathrm{Id}\right)$ is

Bosonizing three-dimensional quiver gauge theories | We start with the recently conjectured 3d bosonization dualities and gauge
