Quantum Spectral Clustering Framework via Compact Circuit Structures

Advanced Quantum Technologies, Volume 9, Issue 10, October 2026.
Can a quantum computer cluster data without ever reading the full kernel? This work shows that compact, parameterized circuits estimate the Laplacian quadratic forms directly and perform clustering, without explicitly constructing the full quantum fidelity‐kernel matrix.

Importance Weighted Directed Graph Variationalauto‐Encoder for Block Modeling of Complex Networks

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 5, October 2026.
ABSTRACT This paper addresses the fundamental challenge of jointly performing node clustering and representation learning in directed and valued graphs, which needs both global and local network structures to be captured. While these two tasks are highly interdependent, they are often treated separately in existing works.

The Hermite Hadamard Inequality on Hypercuboid

JOURNAL OF ADVANCES IN MATHEMATICS, 2019
Given any a := (a1; a2,... ; an) and b := (b1; b2;... ; bn) in Rn. The n-fold convex function dened on [a; b], a; b 2 Rn with a < b is a convex function in each variable separately. In this work we prove an inequality of Hermite-Hadamard type for n-fold convex functions. Namely, we establish the inequality

A reverse Hadamard inequality

Linear Algebra and its Applications, 1996
Let \(U\) be a unitary \(n\times n\) matrix with determinant equal to 1. Let \(A\) be an \(n\times n\) real matrix with rank at most 2 and all entries at least 1. Then \(\text{det} (A\bullet U) \geq 1\), where \(A\bullet U\) is the elementwise product of \(A\) and \(U\).

Integral inequalities for some convex functions via generalized fractional integrals

Journal of Inequalities and Applications, 2018
In this paper, we obtain the Hermite–Hadamard type inequalities for s-convex functions and m-convex functions via a generalized fractional integral, known as Katugampola fractional integral, which is the generalization of Riemann–Liouville fractional ...

Distributed k‐WTA Network for Multi‐Manipulator Competition With Experimental Verifications

CAAI Transactions on Intelligence Technology, Volume 11, Issue 5, Page 1600-1612, October 2026.
ABSTRACT In this article, a new distributed k $k$‐winner‐take‐all (Dk $k$‐WTA) network is designed and used to construct a dynamic allocation scheme for competitive coordination tasks of multiple manipulators as embodied agents. The scheme is constructed based on the following two aspects. On one hand, with reference to a perspective that the Laplacian

A Competitive Model via kWTA Network for Multi‐Agent Systems Considering Noise and Communication Disturbances

CAAI Transactions on Intelligence Technology, Volume 11, Issue 5, Page 1333-1344, October 2026.
ABSTRACT The k $k$‐winners‐take‐all (k $k$WTA) problem, as a competitive selection strategy, is crucial in multi‐agent systems. However, existing noise‐robust k $k$WTA networks mainly address noise while overlooking communication disturbances. The coexistence of both factors significantly degrades solution accuracy and hinders distributed consensus ...

Panel Sequential Group Estimation of Interactive Effects Models

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 5, Page 1248-1266, October 2026.
ABSTRACTThis paper proposes a novel procedure to identify latent groups in the slopes of panel data models with interactive effects. The method is straightforward to apply and relies only on closed‐form estimators when evaluating the objective function. This achieves substantial computational gains compared to alternative non‐linear methods and enables

Improved Hermite–Hadamard Inequality Bounds for Riemann–Liouville Fractional Integrals via Jensen’s Inequality

Fractal and Fractional
This paper derives the sharp bounds for Hermite–Hadamard inequalities in the context of Riemann–Liouville fractional integrals. A generalization of Jensen’s inequality called the Jensen–Mercer inequality is used for general points to find the new and ...
