Algorithms and error bounds for multivariate piecewise constant approximation [PDF]
, 2011 We review the surprisingly rich theory of approximation of functions of many vari- ables by piecewise constants. This covers for example the Sobolev-Poincar´e inequalities, parts of the theory of nonlinear approximation, Haar wavelets and tree ...

Topological structures of fuzzy neutrosophic rough sets [PDF]
Neutrosophic Sets and Systems, 2015 In this paper, we examine the fuzzy neutrosophic relation having a special property that can be equivalently characterised by the essential properties of the lower and upper fuzzy neutrosophic rough approximation operators. Further, we prove that the set

Approximation numbers of an infinite matrix on HpB spaces [PDF]
Egyptian Journal of Pure and Applied ScienceIn this paper, we study conditions that an infinite matrix has to satisfy in order to define a linear bounded operator from any weighted HpB space[1] with a weighted sequence of positive numbers into itself, and give upper and lower estimations of the ...

T-upper approximation spaces [PDF]
Journal of Korean Institute of Intelligent Systems, 2005 We define extensional spaces. Moreover, we investigate the relations among T-upper-approximation spaces, T-quasi -equivalence relations and extensional spaces.

Soft Covering Based Rough Sets and Their Application
The Scientific World Journal, 2014 Soft rough sets which are a hybrid model combining rough sets with soft sets are defined by using soft rough approximation operators. Soft rough sets can be seen as a generalized rough set model based on soft sets.

Variational Inference via Rényi Bound Optimization and Multiple-Source Adaptation
Entropy, 2023 Variational inference provides a way to approximate probability densities through optimization. It does so by optimizing an upper or a lower bound of the likelihood of the observed data (the evidence).

Streaming Algorithms with Large Approximation Factors [PDF]
, 2022 We initiate a broad study of classical problems in the streaming model with insertions and deletions in the setting where we allow the approximation factor α to be much larger than 1.

Approximability of the upper chromatic number of hypergraphs
Discrete Mathematics, 2015 A C-coloring of a hypergraph ${\cal H}=(X,{\cal E})$ is a vertex coloring $φ: X\to {\mathbb{N}}$ such that each edge $E\in{\cal E}$ has at least two vertices with a common color. The related parameter $\overlineχ({\cal H})$, called the upper chromatic number of ${\cal H}$, is the maximum number of colors can be used in a C-coloring of ${\cal H}$.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.
