On the learnability of vector spaces

open access: yesJournal of Computer and System Sciences, 2002
AbstractThe central topic of the paper is the learnability of the recursively enumerable subspaces of V∞/V, where V∞ is the standard recursive vector space over the rationals with (countably) infinite dimension and V is a given recursively enumerable subspace of V∞.

Quantum Thetas on Noncommutative T^4 from Embeddings into Lattice

open access: yes, 2007
In this paper we investigate the theta vector and quantum theta function over noncommutative T^4 from the embedding of R x Z^2. Manin has constructed the quantum theta functions from the lattice embedding into vector space (x finite group).

Deriving a Representative Vector for Ontology Classes with Instance Word Vector Embeddings

open access: yes, 2017
Selecting a representative vector for a set of vectors is a very common requirement in many algorithmic tasks. Traditionally, the mean or median vector is selected.

On Integration in Vector Spaces [PDF]

open access: yesTransactions of the American Mathematical Society, 1938
Introduction. Several authors ([3]-[10], inclusive; [15])t have already given generalized Lebesgue integrals for functions x(s) whose values lie in a Banach space (B-space) X.: In the following pages another definition,? based on the linear functionals over X and on the ordinary Lebesgue integral,11 will be given and its properties and relationships to

Hyperspaces of topological vector spaces: their embedding in topological vector spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
Let L L be a real (Hausdorff) topological vector space. The space K [ L ] \mathcal {K}[L] of nonempty compact subsets of L L forms a (Hausdorff) topological semivector space with singleton origin when K [ L

Vector cross product in n-dimensional vector space [PDF]

open access: yes, 2013
The definition of vector cross product (VCP) introduced by Eckmann only exists in thethree- and the seven- dimensional vector space. In this paper, according to the orthogonal completeness, magnitude of basis vector cross product and all kinds of ...

Reflectors on vector spaces

open access: yesLinear Algebra and its Applications, 1993
The authors define a reflector on a vector space \(V\) to be an additive involutory function \(\sigma\) of \(V\) onto itself. The range of \({1\over 2}[I+\sigma]\) is called the speculum of \(\sigma\). The paper gives some basic results on reflectors and results for reflectors which preserve or invert the specula of other reflectors.

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

open access: yesPopulation Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using
