Stable and Accurate Feature Selection
In addition to accuracy, stability, having not too significant changes in the selected features when the identity of samples change, is also a measure of success for a feature selection algorithm. Stability could especially be a concern when the number of samples in a data set is small and the dimensionality is high. In this study, we introduce a stability measure that can be used for the case ...
متن کاملStable Spectral Mesh Filtering
The rapid development of 3D acquisition technology has brought with itself the need to perform standard signal processing operations such as filters on 3D data. It has been shown that the eigenfunctions of the Laplace-Beltrami operator (manifold harmonics) of a surface play the role of the Fourier basis in the Euclidean space; it is thus possible to formulate signal analysis and synthesis in th...
متن کاملExplicit off-line criteria for stable accurate time filtering of strongly unstable spatially extended systems.
Many contemporary problems in science involve making predictions based on partial observation of extremely complicated spatially extended systems with many degrees of freedom and physical instabilities on both large and small scales. Various new ensemble filtering strategies have been developed recently for these applications, and new mathematical issues arise. Here, explicit off-line test crit...
متن کاملStable and accurate interface capturing advection schemes
In this paper, stable and “low-diffusive” multidimensional interface capturing (IC) schemes using slope limiters are discussed. It is known that direction-by-direction slope-limited MUSCL schemes create geometrical artefacts and thus return a poor accuracy. We here focus on this particular issue and show that the reconstruction of gradient directions are an important factor of accuracy. The use...
متن کاملStable and High Order Accurate Heat Transfer
This paper analyzes stability and convergence properties of a conjugate heat transfer problem in one space dimension. The energy method is used to derive boundary and interface conditions and to prove that the semi-discrete problem is stable. The numerical scheme is implemented using 2nd-, 3rdand 4th-order finite difference operators on Summation-By-Parts (SBP) form. The boundary and interface ...
