Equal opportunities for higher education are the practical requirements of "equality before the scores." china's Extra Credit Policy in the college entrance examination against the education fair,does not conform to the logic of their own education law,should be largely *** for the "disadvantaged" category points can be temporarily retained,but should be a fundamental measure to increase investment in education of vulnerable groups,and when conditions are ripe to be *** the same time,meet the people's interests and expertise of the development of higher education based on their own logic,the need for "sub-professional exam system."

传统K-means算法对初始聚类中心的选取和样本的输入顺序非常敏感,容易陷入局部最优。针对上述问题,提出了一种基于遗传算法的K-means聚类算法GKA,将K-means算法的局部寻优能力与遗传算法的全局寻优能力相结合,通过多次选择、交叉、变异的遗传操作,最终得到最优的聚类数和初始质心集,克服了传统K-means算法的局部性和对初始聚类中心的敏感性。

Based on the actual survey of 724 rural households in 21 townships of Sichuan Province,this article analyzes the basic information,basic characteristics and problems in current china's farmland *** results show that the rural land contractual management right is relatively stable;in farmland transfer market,the degree of development of farmland transfer-out market is higher than that of farmland transfer-in market;at the same time,there are many problems,such as fragmentation of rural land resources allocation,incomplete land property rights system,too powerful land security function,single land transfer pattern and unsound transfer *** countermeasures are put forward as follows:unifying urban and rural planning,and adjusting distribution pattern of rural land in concert with the course of urbanization;improving land property rights system,so that the farmers have the land contractual management right with real right tendency;strengthening the legal construction of land transfer,regulating the land transfer process,and guiding regularized and legalized development of land transfer;promoting farmers' cognitive level,and establishing the intermediary platform to provide land transfer information,ensuring information symmetry between both sides of transfer;providing more non-agricultural jobs,establishing and improving social security system for farmers,and diluting the social security function of land.

第24届中国控制与决策会议

This paper proposes a generic criterion that defines the optimum number of basis functions for radial basis function （RBF） neural networks. The generalization performance of an RBF network relates to its prediction capability on independent test data. This performance gives a measure of the quality of the chosen model. An RBF network with an overly restricted basis gives poor predictions on new data, since the model has too little flexibility. By contrast, an RBF network with too many basis functions also gives poor generalization performance since it is too flexible and fits too much of the noise on the training data. Bias and variance are complementary quantities, and it is necessary to assign the number of basis function optimally in order to achieve the best compromise between them. In this paper we use Stein’s unbiased risk estimator to derive an analytical criterion for assigning the appropriate number of basis functions. Two cases of known and unknown noise have been considered and the efficacy of this criterion in both situations is illustrated experimentally. The paper also shows an empirical comparison between this method and two well known classical methods, cross validation and the Bayesian information criterion, BIC.
