人工股市(Artificial Stock Market,简称ASM)是模拟股市运作的一个程序。在这个电脑中的虚拟市场中,若干被称为交易者的人工智能程序(Agent)通过观察它们所在的数字世界中股价和股息的不断变换而做出预测,并且根据这些预测做出购买股票与否以及购买股票数量的决策。反过来,所有的交易者的决策又决定了股票的价格,这样,整个的股票交易市场就构成了一个自我封闭的计算系统。同时,这些交易者都具有学习的能力,可以根据以前预测的成功或者失败对自己的决策进行调整,并且通过一种被称为遗传算法的方法产生创新能力。总之,ASM是一个电脑中不断进化的虚拟股票市场!通过研究ASM,我们可以更好的理解现实世界的行为,并且它提供了一个很好的现实股市的隐喻。 备注:该程序运行需要有Swarm平台的支持,关于这个平台可以到http://www.swarm.org免费下载。 -artificial stock market (Artificial Stock Market, or ASM) is a stock market simulation operation of the procedure. In this computer in the virtual market, a number of traders known as artificial intelligence (Agent) by observing them where the digital world and the stock dividend and the constantly changing projections, and based on these projections made whether or not to purchase stocks and the purchase of shares in decision-making. Conversely, all the decision-making transactions in turn determines the share price, so that the entire stock market would constitute a self-enclosed computer system. Moreover,

提出了基于最小化估计的泛化误差界非优化估计方法。目前大多数的核参数选择方法都是通过极小化了来得到最优参数值,但是求解优化问题的计算代价相当的大,并且不能很好地体现数据的分布特征。本文采用非优化技术,通过极小化泛化误差来优化核及相关参数,由于直接计算最小半径和最大间隔,避免了对优化问题的直接求解,因此可以很好地降低计算代价。并且该方法直接从样本出发,可以很好地体现数据的分布特征,不管数据分布是否均匀都可以适用。给出了基于凸包估计的SVM核选择的模型及实现算法。
-Proposed based on minimizing the estimated generalization error bound of the non-optimal estimation method. Most of the nuclear parameter selection methods are to get the best by minimizing the parameter values, but the computational cost for solving optimization problems is quite large, and can not properly reflect the distribution characteristics of the data. In this paper, the non-optimization technology, by minimizing the generalization error to optimize the nuclear and related parameters, due to the direct calculation of the minimum radius and maximum interval, avoiding the direct solution of the optimization problem, it can very well reduce the computation cost. And that the method directly from the sample one can well reflect the distribution chara
