Size and Complexity in Model Financial Systems [PDF]
SSRN Electronic Journal, 2012 The global financial crisis has precipitated an increasing appreciation of the need for a systemic perspective toward financial stability. For example: What role do large banks play in systemic risk? How should capital adequacy standards recognize this role? How is stability shaped by concentration and diversification in the financial system?

Segmentation of 3D meshes combining the artificial neural network classifier and the spectral clustering [PDF]
Компьютерная оптика, 2018 3D mesh segmentation has become an essential step in many applications in 3D shape analysis. In this paper, a new segmentation method is proposed based on a learning approach using the artificial neural networks classifier and the spectral clustering for

Isometric Shape Representation by Integrating Shape Function Maps and Deep Learning
IEEE Access, 2019 With the wide application of isometric 3D models, the representation and recognition of them receive increasing attention. Most existing methods for shape representation and analysis either focus on using the constrained hand-craft models or purely ...

Models for Visualisation of Complex Information Systems [PDF]
2012 16th International Conference on Information Visualisation, 2012 Modular approaches (objects, components and service-based) offer efficient solutions to face the complexity of Information Systems. However, today they involve major problems in dealing with data/information and decisionmaking (from the standpoint of the end- user).

On the Convergence Rate of Quasi-Newton Methods on Strongly Convex Functions with Lipschitz Gradient
Mathematics, 2023 The main results of the study of the convergence rate of quasi-Newton minimization methods were obtained under the assumption that the method operates in the region of the extremum of the function, where there is a stable quadratic representation of the ...

Algorithms and models for complex natural systems [PDF]
Natural Computing, 2015 Analysing genomic data and complex natural phenomena in computational terms enhances our comprehension of both nature and computation. Thus, a cross fertilization of algorithms and models for natural complex systems at molecular, cellular, or higher levels, became an active research area, and a more in depth investigation of mutual relationships ...

Exploiting Opportunistic Coding in Throwbox-Based Multicast in Vehicular Delay Tolerant Networks
IEEE Access, 2019 In vehicular delay tolerant networks (VDTNs), multicast has been increasingly popular due to new applications, among which large contents such as multimedia files play a major role. Under this circumstance, existing works have failed to provide efficient
