Secure Federated Matrix Factorization [PDF]
IEEE Intelligent Systems, 2019 To protect user privacy and meet law regulations, federated (machine) learning is obtaining vast interests in recent years. The key principle of federated learning is training a machine learning model without needing to know each user’s personal raw ...

Factorization method for solving nonlocal boundary value problems in Banach space
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 This article deals with the factorization and solution of nonlocal boundary value problems in a Banach space of the abstract form B1 u = A u - S Φ( u )- G Ψ(A0 u) = f, u ∈ D (B1) , where A, A0 are linear abstract operators, S, G are vectors of functions,

Cycle frames and the Oberwolfach problem
AKCE International Journal of Graphs and Combinatorics, 2019 For an integer denotes a graph with uniform edge-multiplicity Let be a subset of positive integers. A 2-regular subgraph of -partite graph containing vertices of all but one partite set is called partial 2-factor, where denotes wreath product and is an ...

Analysis of the RSA-cryptosystem in abstract number rings
Журнал Белорусского государственного университета: Математика, информатика, 2020 Quantum computers can be a real threat to some modern cryptosystems (such as the RSA-cryptosystem). The analogue of the RSA-cryptosystem in abstract number rings is not affected by this threat, as there are currently no factorization algorithms using ...

Continuous Homomorphisms Defined on (Dense) Submonoids of Products of Topological Monoids
Axioms, 2020 We study the factorization properties of continuous homomorphisms defined on a (dense) submonoid S of a Tychonoff product D = ∏ i ∈ I D i of topological or even topologized monoids.

On Koopman and Perron-Frobenius operators of random dynamical systems
ESAIM: Proceedings and Surveys, 2014 In this paper, we investigate the Koopman and the Perron-Frobenius operators of random dynamical systems in general setting. Moreover, we give some necessary and sufficient conditions for the existence of invariant densities for the ...

Relating Transverse Momentum Dependent and Collinear Factorization Theorems in a Generalized Formalism [PDF]
, 2016 We construct an improved implementation for combining transverse-momentum-dependent (TMD) factorization and collinear factorization. TMD factorization is suitable for low transverse momentum physics, while collinear factorization is suitable for high ...
