Activity coefficients of binary methanol alcohol mixtures from cluster weighting
ChemistryOpen, 2020 The hydrogen bond network of different small alcohols is investigated via cluster analysis. Methanol/alcohol mixtures are studied with increasing chain length and branching of the molecule.

Semivalues: weighting coefficients and allocations on unanimity games [PDF]
Optimization Letters, 2017 Each semivalue, as a solution concept defined on cooperative games with a finite set of players, is univocally determined by weighting coefficients that apply to players’ marginal contributions. Taking into account that a semivalue induces semivalues on lower cardinalities, we prove that its weighting coefficients can be reconstructed from the last ...

Multi-Loss Weighting with Coefficient of Variations [PDF]
2021 IEEE Winter Conference on Applications of Computer Vision (WACV), 2021 Many interesting tasks in machine learning and computer vision are learned by optimising an objective function defined as a weighted linear combination of multiple losses. The final performance is sensitive to choosing the correct (relative) weights for these losses.

Efficient computation of the Weighted Clustering Coefficient [PDF]
Internet Mathematics, 2014 The clustering coefficient of an unweighted network has been extensively used to quantify how tightly connected is the neighbor around a node and it has been widely adopted for assessing the quality of nodes in a social network. The computation of the clustering coefficient is challenging since it requires to count the number of triangles in the graph.

A weighted transplantation theorem for Jacobi coefficients [PDF]
Journal of Approximation Theory, 2019 We present a transplantation theorem for Jacobi coefficients in weighted spaces. In fact, by using a discrete vector-valued local Calderón-Zygmund theory, which has recently been furnished, we prove the boundedness of transplantation operators from $\ell^p(\mathbb{N},w)$ into itself, where $w$ is a weight in the discrete Muckenhoupt class $A_{p ...
