Three-Dimensional Flow Stability Analysis Based on the Matrix-Forming Approach Made Affordable
(2017-01-01)
Theoretical developments for hydrodynamic instability analysis are often based on eigenvalue problems, the size of which depends on the dimensionality of the reference state (or base flow) and the number of coupled equations ...
Generating unconstrained two-dimensional non-guillotine cutting patterns by a Recursive Partitioning Algorithm
(PALGRAVE MACMILLAN LTDBASINGSTOKE, 2013-08-02)
In this study, a dynamic programming approach to deal with the unconstrained two-dimensional non-guillotine cutting problem is presented. The method extends the recently introduced recursive partitioning approach for the ...
Explaining dimensionality reduction results using Shapley values
(2021-09-15)
Dimensionality reduction (DR) techniques have been consistently supporting high-dimensional data analysis in various applications. Besides the patterns uncovered by these techniques, the interpretation of DR results based ...
A restricted boltzmann machine-based approach for robust dimensionality reduction
(2018-01-31)
Data dimensionality is an important issue to be adressed by pattern recognition systems. Despite of storage and processing, working with high-dimensional feature vectors also requires complex optimization methods. A proper ...

Contrastive analysis for scatterplot-based representations of dimensionality reduction
(2021-01-01)
Cluster interpretation after dimensionality reduction (DR) is a ubiquitous part of exploring multidimensional datasets. DR results are frequently represented by scatterplots, where spatial proximity encodes similarity among ...
Forecasting conditional covariance matrices in high-dimensional time series: a general dynamic factor approach
(2019-06)
Based on a General Dynamic Factor Model with infinite-dimensional factor space, we develop a new estimation and forecasting procedures for conditional covariance matrices in high-dimensional time series. The performance ...
Photodisintegration of H-3 in a three dimensional faddeev approach
(E D P Sciences, 2009-01-01)
An interaction of a photon with H-3 is invstigated based on a three dimensional Faddeev approach. In this approach the three-nucleon Faddeev equations with two-nucleon interactions are formulated with consideration of the ...
