Semantic visualization for spherical representation
Proceedings of the 20th ACM SIGKDD international conference on Knowledge discovery and data mining, 2014 Visualization of high-dimensional data such as text documents is widely applicable. The traditional means is to find an appropriate embedding of the high-dimensional representation in a low-dimensional visualizable space. As topic modeling is a useful form of dimensionality reduction that preserves the semantics in documents, recent approaches aim for ...

On quiver W-algebras and defects from gauge origami
Physics Letters B, 2020 In this note, using Nekrasov's gauge origami framework, we study two different versions of the BPS/CFT correspondence – first, the standard AGT duality and, second, the quiver W algebra construction which has been developed recently by Kimura and Pestun.

Radiation fields in radiative transfer: Spherical-wavelet representation
Journal of Quantitative Spectroscopy and Radiative Transfer, 2020 Abstract The spherical wavelet based on the lifting scheme is introduced for adaptive discrete-ordinate sampling of the radiation fields, particularly, in the radiative transfer computation using iterative schemes. The lifting scheme for wavelet transform is described from an implementation point of view, including the construction of hierarchical ...

Complete Irreducibility and X-Spherical Representations
Journal of Functional Analysis, 1993 Let \(G\) be a locally compact group, \(K\) a compact subgroup and \(\chi:K \to \{| z |=1\}\) be a continuous homomorphism. Let \(\pi\) be a continuous representation of \(G\) on a complete locally convex space \(V\) such that the subspace \(V(\chi)=\{v \in V \mid \pi(k) v=\chi(k)v,\;k \in K\}\) is one-dimensional. The author shows that \(\pi\) is then

Low-Order Spherical Harmonic HRTF Restoration Using a Neural Network Approach
Applied Sciences, 2020 Spherical harmonic (SH) interpolation is a commonly used method to spatially up-sample sparse head related transfer function (HRTF) datasets to denser HRTF datasets.

MODELS OF IMAGES WITH RADIAL-CIRCULAR STRUCTURE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 The overwhelming majority of known image models are varieties of random fields defined on rectangular two-dimensional grids or grids of higher dimension, for example.

Geometrical Model of Visible Angle Discrimination
RUDN Journal of Psychology and Pedagogics, 2012 The geometrical model of discrimination of four-line diagrammatic representations, made with the multidimensional scaling method of subjective estimations of perceived pairwise differences between pictures is described in the article.
