Convergence of online learning algorithm with a parameterized loss

open access: yesAIMS Mathematics, 2022
The research on the learning performance of machine learning algorithms is one of the important contents of machine learning theory, and the selection of loss function is one of the important factors affecting the learning performance.

An exact one-particle theory of bosonic excitations: from a generalized Hohenberg–Kohn theorem to convexified N-representability

open access: yesNew Journal of Physics, 2023
Motivated by the Penrose–Onsager criterion for Bose–Einstein condensation we propose a functional theory for targeting low-lying excitation energies of bosonic quantum systems through the one-particle picture.

Near-Convex Archetypal Analysis [PDF]

open access: yesIEEE Signal Processing Letters, 2020
Nonnegative matrix factorization (NMF) is a widely used linear dimensionality reduction technique for nonnegative data. NMF requires that each data point is approximated by a convex combination of basis elements. Archetypal analysis (AA), also referred to as convex NMF, is a well-known NMF variant imposing that the basis elements are themselves convex ...

AutoBar: Automatic Barrier Coverage Formation for Danger Keep Out Applications in Smart City

open access: yesSensors, 2023
Barrier coverage is a fundamental application in wireless sensor networks, which are widely used for smart cities. In applications, the sensors form a barrier for the intruders and protect an area through intrusion detection.

Convex analysis and thermodynamics [PDF]

open access: yesKinetic & Related Models, 2013
Convex analysis is very useful to prove that a material model fulfills the second law of thermodynamics. Dissipation must remains non-negative and an elegant way to ensure this property is to construct an appropriate pseudo-potential of dissipation.

Sparse Regularization via Convex Analysis [PDF]

open access: yesIEEE Transactions on Signal Processing, 2017
Sparse approximate solutions to linear equations are classically obtained via L1 norm regularized least squares, but this method often underestimates the true solution.

General optimal euclidean Sobolev and Gagliardo-Nirenberg inequalities

open access: yesAnais da Academia Brasileira de Ciências, 2005
We prove general optimal euclidean Sobolev and Gagliardo-Nirenberg inequalities by using mass transportation and convex analysis results. Explicit extremals and the computation of some optimal constants are also provided.

Convexity in Real Analysis [PDF]

open access: yesReal Analysis Exchange, 2011
We treat the classical notion of convexity in the context of hard real analysis. Definitions of the concept are given in terms of defining functions and quadratic forms, and characterizations are provided of different concrete notions of convexity. This analytic notion of convexity is related to more classical geometric ideas.
