Combining Static and Dynamic Features for Multivariate Sequence Classification | Model precision in a classification task is highly dependent on the feature
space that is used to train the model. Moreover, whether the features are
sequential or static will dictate which classification method can be applied as
most of the machine learning algorithms are designed to deal with either one or
another ... | 1 | 0 | 0 | 1 | 0 | 0 |
Tracking the gradients using the Hessian: A new look at variance reducing stochastic methods | Our goal is to improve variance reducing stochastic methods through better
control variates. We first propose a modification of SVRG which uses the
Hessian to track gradients over time, rather than to recondition, increasing
the correlation of the control variates and leading to faster theoretical
convergence close t... | 1 | 0 | 0 | 1 | 0 | 0 |
On spectral properties of Neuman-Poincare operator and plasmonic resonances in 3D elastostatics | We consider plasmon resonances and cloaking for the elastostatic system in

A hybridizable discontinuous Galerkin method for the Navier--Stokes equations with pointwise divergence-free velocity field | We introduce a hybridizable discontinuous Galerkin method for the

Battery Degradation Maps for Power System Optimization and as a Benchmark Reference | This paper presents a novel method to describe battery degradation. We use

Computer Assisted Localization of a Heart Arrhythmia | We consider the problem of locating a point-source heart arrhythmia using
