Description: Support Vector Machines, one of the new techniques for pattern classifi cation, have been widely used in many application areas. The kernel parameters setting for SVM in a training process impacts on the classifi cation accuracy. Feature selection is another factor that impacts classifi cation accuracy. The objective of this research is to simultaneously optimize the parameters and feature subset without degrading the SVM classifi cation accuracy. We present a genetic algorithm approach for feature selection and parameters optimization to solve this kind of problem.

[Special EffectsGenetic-algorithms-

Description: 本文主要介绍遗传算法的基本理论,叙述遗传算法在图像增强的的主要应用,即将原始图像变得更加清晰,特征变得更加明显。 现今关于图像增强的算法有很多,而这些算法大多是基于退化函数或者点扩展函数的知识进行图像处理的。当图像出现模糊或噪声影响大时,设计出的图像清晰化的效果肯定不够理想,因此有必要对图像进行增强处理。于是,可利用到遗传算法这种成熟稳定的仿生物进化的全局寻优算法,进行图像增强,由于遗传算法控制参数少、自适应度高,将选择该方法对图像退化分别进行不同的清晰化处理. 这样既增强了图像的对比度,又克服了传统直方图均衡化处理所造成的灰度级损失等缺点。 通过实验去表明,遗传算法从全局寻优的角度出发,能够较为精确地估计退化系统函数。和传统的线性增强、直方图均衡进行比较。实验结果表明该方法能改善原图像视觉效果,便于之后的图像分析。 -This paper mainly introduces the basic theory of genetic algorithm, genetic algorithm (ga) in the main application of image enhancement, the original image is more clear, characteristic becomes more obvious. Today about the image enhancement algorithm are many, and most of these algorithms is based on the degradation function or the knowledge of the point spread function of image processing. When the image appears fuzzy or noise influence, designed the image clarity of effect must not ideal, therefore it is necessary to enhance the image. Then, genetic algorithm is available to the mature and stable evolution of the global optimization algorithm, for image enhancement, due to less genetic algorithm control parameters, since the high fitness, will choose the method of image degradation, respectively, to manipulate the different motivation. It can enhance the image contrast, and overcome the traditional histogram equalization processing grayscale loss caused by the faults. Throug

[matlabReal-Coded-Genetic-Algorithm-for-Robust

Description: Power system stabilizers (PSS) are now routinely used in the industry to damp out power system oscillations. In this paper, real-coded genetic algorithm (RCGA) optimization technique is applied to design robust power system stabilizer for both singlemachine infinite-bus (SMIB) and multi-machine power system. The design problem of the proposed controller is formulated as an optimization problem and RCGA is employed to search for optimal controller parameters. By minimizing the time-domain based objective function, in which the deviation in the oscillatory rotor speed of the generator is involved stability performance of the system is improved. The non-linear simulation results are presented under wide range of operating conditions disturbances at different locations as well as for various fault clearing sequences to show the effectiveness and robustness of the proposed controller and their ability to provide efficient damping of low frequency oscillations.-Power system stabilizers (PSS) are now routinely used in the industry to damp out power system oscillations.

[AI-NN-PRFunction optimization algorithm

Description: 遗传算法提供了求解非线性规划的通用框架,它不依赖于问题的具体领域。遗传算法的优点是将问题参数编码成染色体后进行优化, 而不针对参数本身, 从而不受函数约束条件的限制; 搜索过程从问题解的一个集合开始, 而不是单个个体, 具有隐含并行搜索特性, 可大大减少陷入局部最小的可能性。而且优化计算时算法不依赖于梯度信息,且不要求目标函数连续及可导,使其适于求解传统搜索方法难以解决的大规模、非线性组合优化问题。(Genetic algorithm provides a general framework for solving nonlinear programming, which does not depend on the specific problem domain. The advantage of genetic algorithm is that the problem parameters are encoded into chromosomes for optimization, rather than the parameters themselves. The search process starts from a set of problem solutions, rather than a single individual, and has the implicit parallel search feature, which can greatly reduce the possibility of falling into the local minimum. Moreover, the algorithm does not rely on gradient information and does not require the objective function to be continuous and differentiable, which makes it suitable for solving large-scale and nonlinear combinatorial optimization problems that are difficult to be solved by traditional search methods.)
