Weighted Association Rule Mining using Weighted Support and Significance Framework [PDF]
, 2003 We address the issues of discovering significant binary relationships in transaction datasets in a weighted setting. Traditional model of association rule mining is adapted to handle weighted association rule mining problems where each item is allowed to

A Weighted Problem for p-Laplacian Discussed with a Result of Saddle Point Type
MathematicsWeighted problems for the p-Laplacian represent a wide range of models arising from real-world research. Solving such problems involves, in many situations, variational approaches that are various and a virtually inexhaustible resource.

Extinction and Positivity of the Solutions for a 𝑝-Laplacian Equation with Absorption on Graphs
Journal of Applied Mathematics, 2011 We deal with the extinction of the solutions of the initial-boundary value problem of the discrete p-Laplacian equation with absorption 𝑢𝑡=Δ𝑝,𝜔𝑢−𝑢𝑞 with p > 1, q > 0, which is said to be the discrete p-Laplacian equation on weighted graphs. For 0 < q < 1,

Coordinated motions of multiple robotic manipulators with matrix-weighted network
Scientific Reports, 2022 This paper addresses coordinated problem of uncertain robotic manipulators with matrix-weighted network. Given interconnections between agents are weighted by nonnegative definite matrices, we present a sufficient and necessary condition about zero ...

Some Applications of the Weighted Combinatorial Laplacian [PDF]
, 2005 The weighted combinatorial Laplacian of a graph is a symmetric matrix which is the discrete analogue of the Laplacian operator. In this thesis, we will study a new application of this matrix to matching theory yielding a new characterization of factor ...

On the bounds for the largest Laplacian eigenvalues of weighted graphs [PDF]
, 2012 We consider weighted graphs, such as graphs where the edge weights are positive definite matrices. The Laplacian eigenvalues of a graph are the eigenvalues of the Laplacian matrix of a graph G.

Extremal graph characterization from the upper bound of the Laplacian spectral radius of weighted graphs [PDF]
, 2007 We consider weighted graphs, where the edge weights are positive definite matrices. In this paper, we obtain two upper bounds on the spectral radius of the Laplacian matrix of weighted graphs and characterize graphs for which the bounds are attained ...

On structural controllability in complex networks with periodic switching topologies
Asian Journal of Control, EarlyView.Abstract This paper investigates the structural controllability of complex networks with periodic switching topologies. First, several graph transformations that preserve structural controllability are demonstrated. Based on the n‐walk theory, a criterion is derived that determines structural controllability by analyzing only the joint graph within a ...

Existence of positive weak solution for a weighted system of autocatalytic reaction steady state type [PDF]
European Journal of Mathematics and ApplicationsWe establish the existence results of positive weak solution for the weighted $p$-Laplacian autocatalytic reaction problem $-\Delta_{P,p}u=\lambda m(x)[\nu a(x)u^{\alpha }-\upsilon u^{\beta }]$ in $\Omega,$ $u=0$ on $\partial \Omega$, where $\Delta _{P,p}
