Abstract

Evolutionary computation is the study of biologically motivated computational paradigms which exert novel ideas and inspiration from natural evolution and adaptation. The application of population-based heuristics in solving Multiobjective Optimization Problems has been receiving a growing interest from computational intelligence community. To search for a family of “acceptable” solutions, a so called Pareto set, by using population-based parallel searching ability, several MultiObjective Evolutionary Algorithms (MOEAs) and MultiObjective Particle Swarm Optimization (MOPSOs) have been proposed. However, most of these designs have difficulty in dealing with the trade-off between uniformly distributing the computational resources and finding the near-complete and near-optimal Pareto set. On the other hand, according to the No Free Lunch theorems, no formal assurance of an algorithm’s general effectiveness exists if insufficient knowledge of the problem characteristics is incorporated into the algorithm domain. In this talk, population control is being implemented in various forms of evolutionary algorithms for the purpose of multiobjective optimization, including genetic algorithm, particle swarm optimization, differential evolution and artificial immune system. We will propose works along this line of research in dynamically regulating the population as needed in different stage of evolutionary process, some voluntary while others compulsory, in pursuing a uniformly distributed, near optimal, and close to complete Pareto front for a given MOP. Through numerical study, we will show these designs incorporating population control strategy provide very competitive performances qualitatively and quantitatively compared to some chosen state-of-the-art evolutionary algorithms.

Abstract

Reversible information allows an original image to be completely restored after the extraction of hidden data embedded in a cover image.

In this talk, I will introduce a reversible scheme for VQ-compressed images that is based on a declustering strategy and takes advantage of the local spatial characteristics of the image.

The main advantages of the method are ease of implementation, low computational demands, and no requirement for auxiliary data.

The experimental results show that the embedding capacity of the proposed method is controlled by the number of declustered groups and the spatial characteristics of the cover image.

The results also show that the proposed method is indeed feasible because it has large embedding capacity and short running time compared with other methods.

Abstract

Cognitive Radio Networks (CRN) technology is an important innovation for the future of communications and likely to be a part of the new wireless standards, becoming almost a necessity for future communications. Due to the flexibility and openness of CRN, it is easy to link CRN to some new techniques and theories. For instance, cooperative spectrum sensing in cognitive radio networks has an analogy to a distributed decision in wireless sensor networks, where each sensor makes a local decision and those decision results are reported to a fusion center to give a final decision according to some fusion rule. The main difference between these two applications lies in the wireless environment. Compared to wireless sensor networks, cognitive radios and the fusion center (or common receiver) are distributed over a larger geographic area. This difference brings out a much more challenging problem to cooperative spectrum sensing because sensing channels (from the primary user to cognitive radios) and reporting channels (from cognitive radios to the fusion center or common receiver) are normally subject to fading or heavy shadowing. In addition, to pursuit advanced intelligent capability and adaptive capacity in any environment at any time, CRN necessiate more inter-behavior as well as stronger calculation ability. Global information grid (GIG) , cloud computing, cooperative distributed planning, which are all dovetailed nicely with the nature of CRN actions, will be helpful and can enable CRN to be more practical and exercisable.
