Topic: Forgetting Curve and Ant Colony Optimization algorithm

The analysis of social networks is concentrated mainly on uncovering hidden relations and properties of network nodes (vertices). Most of the current approaches are focused mainly on different network types and network coefficients. On one hand, the analysis can be relatively simple and on the other hand more complex approaches to network dynamics can be used. In this lecture we introduce a novel social network analysis based on the so-called Forgetting Curve and Ant Colony Optimization (ACO) algorithm. We analyze a co-authorship network and identify two types of ties among its nodes. The Forgetting Curve and ACO are used to model the dynamics of such a network.
One of the most relevant features of social networks is the community structure. Since these networks are typically very complex, it is great interest to reduce these networks to much simpler. Clustering and low dimensional representation of high dimensional data are important problems in many diverse fields. In recent years various spectral methods to perform these tasks, based on the eigenvectors of adjacency matrices of graphs on the data have been developed. One of the successful models is based on theory of diffusion equation. It is closely related to Schrodingerˇ¦s Equation for a free particle. The diffusion equation is used for measure of diffusion distance. We apply diffusion distance for social network partitioning.

Topic: The study for Utilizing Organic Computing to Construct a Ubiquitous Wireless Network

Organic Computing is a computing form with similar human organic biologically properties. It can be self-adaptive for any condition. As the rapid progress in information network, the people are surrounded by all kinds of information. Besides specific expert, common user is unable to fully understand this information has according to oneˇ¦s wishes. In order to solve this problem, we must develop a computation form for people's need which posses the elasticity and automatic operation, we call it "organic computing". Any system with these properties, we call it an "organic computing system". Hence, an "Organic Computing System" is a technical system, which adapts dynamically to the current conditions of its environment.
This research will induct the organic computing to Ubiquitous wireless network. We use the characteristic of organic computing to solve the problems of the Ubiquitous wireless network. For example, we use the self-organizationˇBself-configuration to solve the problem of device management of mobile Ad-hoc network architecture. We use the self-optimization to solve the problem of routing for the fast moving mobile terminals. We use the self-protection to solve the problem of link security. We use the self-healing to solve the network problem of the power limit.

Evolutionary computation is the study of biologically motivated computational paradigms which exert novel ideas and inspiration from natural evolution and adaptation. The applications of population-based heuristics in solving constrained and dynamic optimization problems have been receiving a growing interest from computational intelligence community. Most practical optimization problems are with the existence of constraints and uncertainties in which the fitness function changes through time and is subject to multiple constraints. In this study, we propose the cultural-based particle swarm optimization (PSO) to solve these problems with real-world complications. A cultural framework is introduced that incorporates the required information from the PSO into five sections of the belief space, namely situational knowledge, temporal knowledge, domain knowledge, normative knowledge, and spatial knowledge. The archived information is exploited to detect the changes in the environment and assists response to the change and constraints through a diversity based repulsion among particles and migration among swarms in the population space, also helps in selecting the leading particles in three different levels, personal, swarm, and global level. Comparison of the proposed cultural based PSO over numerous challenging constrained and dynamic benchmark problems demonstrates the competitive, if not appreciably much better, performance with respect to selected state-of-the-art PSO heuristics.
In addition, an ensemble method on performance metrics is proposed, knowing no single metric alone can faithfully quantify the performance of a given design under real-world scenarios. A collection of performance metrics, measuring the spread across the Pareto-optimal front and the ability to attain the global trade-off surface closeness, could be incorporated into the ensemble approach. This design allows a comprehensive measure and more importantly reveals additional insight pertaining to specific problem characteristics that the underlying MOEA could perform the best.
