  SVM Multiregression for Non Linear Channel Estimation in Multiple-Input Multiple-Output Systems 在多输入多输出系统中的SVM多元回归非线性逼近(This paper addresses the problem of Multiple-Input Multiple-Output (MIMO) frequency non-selective channel estimation. We develop a new method for multiple variable regression estimation based on Sup- port Vector Machines, a state-of-the-art technique within the machine learning community for regression estimation. We show how this new method, that we call M-SVR, can be effi ciently solved. The pro- posed regression method is evaluated in a MIMO system under a channel estimation scenario, showing its benefi ts in comparison to previous proposals when non linearities are present in either the transmitter or the receiver sides of the MIMO system.)

  自适应GA SVM 参数选择算法研究Param eter selection algorithm for support vector machines based on adaptive genetic algorithm 支持向量机是一种非常有前景的学习机器, 它的回归算法已经成功地用于解决非线性函数的逼近问题. 但 是, SVM 参数的选择大多数是凭经验选取, 这种方法依赖于使用者的水平, 这样不仅不能获得最佳的函数逼近效果, 而且采用人工的方法选择 SVM 参数比较浪费时间, 这在很大程度上限制了它的应用. 为了能够自动地获得最佳的 SVM 参数, 提出了基于自适应遗传算法的 SVM 参数选取方法. 该方法根据适应度值自动调整交叉概率和变异概率, 减少了遗传算法的收敛时间并且提高了遗传算法的精度, 从而确保了 SVM 参数选择的准确性. 将该方法应用于船用 锅炉汽包水位系统建模, 仿真结果表明由该方法所得的 SVM 具有较简单的结构和较好的泛化能力, 仿真精度高, 具 有一定的理论推广意义.( The support vector m achine ( SVM ) is a prom ising artificia l inte lligence technique, in w hich the regres sion a lgorithm has a lready been used to so lve the nonlinear function approach successfully.

  深度优先搜索的支持向量机参数优化算法 Study on Parameters Optimization of Support Vector Machines Based on DFS :研究支持向量机参数优化问题,由于算法要求准确选择 SVM 参数,支持向量机在处理大样本数据集时和最优模型参 数确定时,消耗的时间长、占有内存大,易获得局部最优解的难题。为了解决支持向量机存在的不足,采用深度优先搜索算 法对其参数优化机机制进行改进。将向量机参数优化视成一个组合优化问题,将支持向量机模型的分类误差作为优化目标 函数,采用深度优先算法对其进行求解,最后将模型应用于 3 个标准分类数据集。仿真结果表明,优化参数后的支持向量机 加快模型的训练速度度,提高了分类的准确率,很好的解决( Study on the problems of support vector machines parameters optimization. The prediction precision of Support vector machines model and generalization ability depend on its parameters reasonable choice. The problems of time - consuming and easy falling into the local optimal value exist in traditional support vector machine parameters optimization algorithm,and support vector machine prediction precision is low. In order to solve the problems,the paper puts forward a method based on depth first search of SVM parameters optimization method ( DFS - SVM) . DFS - SVM takes SVM parameters optimization as a combinatorial optimization problem and the RMSE as optimization goal,uses depth first search to select SVM parameters,and tests DFS - SVM performaces through three standard data set. Simulation experiment results show that the DFS - SVM prediction accuracy is improved and the training time is shorten greatly. It provides a new effective solution for SVM parameters optimizat)
