Infinite multisets: Basic properties and cardinality [PDF]
Notes on Number Theory and Discrete MathematicsThis research work presents the topic of infinite multisets, their basic properties and cardinality from a somewhat different perspective. In this work, a new property of multisets, ‘m-cardinality’, is defined using multiset functions.

More accurate cardinality estimation in data streams
Electronics Letters, 2022 Many sketches based on estimator sharing have been proposed to estimate cardinality with huge flows in data streams. However, existing sketches suffer from large estimation errors due to allocating the same memory size for each estimator without ...

Cardinality-constrained Portfolio Selection via Two-timescale Duplex Neurodynamic Optimization
, 2022 This paper addresses portfolio selection based on neurodynamic optimization. The portfolio selection problem is formulated as a biconvex optimization problem with a variable weight in the Markowitz risk–return framework.

On Some Similarity Measures of Single Valued Neutrosophic Rough Sets [PDF]
Neutrosophic Sets and Systems, 2019 In this paper we have obtained the similarity measures between single valued neutrosophic rough sets by analyzing the concept of its distance between them and studied its properties.

The Development of Arabic Digit Knowledge in 4- to 7-Year-Old Children
Journal of Numerical Cognition, 2015 Recent studies indicate that Arabic digit knowledge rather than non-symbolic number knowledge is a key foundation for arithmetic proficiency at the start of a child’s mathematical career.

Equivalence of Partition Functions Leads to Classification of Entropies and Means
Entropy, 2012 We derive a two-parameter family of generalized entropies, <em>S<sub>pq</sub></em>, and means <em>m<sub>pq</sub></em>. To this end, assume that we want to calculate an entropy and a mean for <em>n</

A Strategy of Efficient and Accurate Cardinality Estimation Based on Query Result [PDF]
Xibei Gongye Daxue Xuebao, 2018 Cardinality estimation is an important component of query optimization. Its accuracy and efficiency directly decide effect of query optimization. Traditional cardinality estimation strategy is based on original table or sample to collect statistics, then

Recognition of small numbers in subset knowers Cardinal knowledge in early childhood
Royal Society Open Science, 2023 Previous research suggests that subset-knowers have an approximate understanding of small numbers. However, it is still unclear exactly what subset-knowers understand about small numbers.
