Stochastic forcing in hydrodynamic models with non-local interactions
Pavel Ludvik, Vaclav Macha
The hydrodynamical model of the collective behavior of animals consists of the Euler equation with additional non-local forcing terms representing the repulsive and attractive forc…
Compressible fluid inside a linear oscillator
Vaclav Macha
We use Feireisl-Lions theory to deduce the existence of weak solutions to a system describing the dynamics of a linear oscillator containing a Newtonian compressible fluid. The app…
Dimension reduction for the compressible Navier-Stokes system with density dependent viscosity
Matteo Caggio, Vaclav Macha
We consider a compressible Navier-Stokes system for a barotropic fluid with density dependent viscosity in a three-dimensional time-space domain where $…
DeepTopPush: Simple and Scalable Method for Accuracy at the Top
Václav Mácha, Lukáš Adam, Václav Šmídl
Accuracy at the top is a special class of binary classification problems where the performance is evaluated only on a small number of relevant (top) samples. Applications include i…
General Framework for Binary Classification on Top Samples
Lukáš Adam, Václav Mácha, Václav Šmídl +1
Many binary classification problems minimize misclassification above (or below) a threshold. We show that instances of ranking problems, accuracy at the top or hypothesis testing m…
Nonlinear classifiers for ranking problems based on kernelized SVM
Václav Mácha, Lukáš Adam, Václav Šmídl
Many classification problems focus on maximizing the performance only on the samples with the highest relevance instead of all samples. As an example, we can mention ranking proble…
