  information weights
The selected clusterers can be combined via voting, or weighted-voting based on re-normalized mutual information weights of the selected clusterers.
      
However, the time cost of computing the mutual information weights is negligible if comparing with that of the k-means clustering process.
      


An analytic method for computing the free distance of convolutional codes and the total information weight from all paths of the same Hamming weight is proposed. The key to this algorithm is to find out all the valid paths. Recursion formulae for computing these paths and the related parameters of convolutional codes are given.. It is shown that this algorithm asks for less storage and computation than all other existing algorithms.

On the basis of practical experiences, this paper elucidates further the principles of logic-information method and introduces various improvements made in order to extend its suitability. The article discusses in detail two aspects of weight value bestowed by logic information method to an indication. The first aspect expresses the relationship between the structure pattern and grade variation of an indication which is called relative difference of weight values of the indication. The second aspect expresses the degree of effectiveness of an indication in combining with other indications to differentiate standard objects of various grades which is called information weight. The improvements in the method are as follows, expanding the two states of an indication into three states, permitting the deficiency of data in individual indication of individual object; using the probability differences between the plus patterns and negative patterns of indications to sift indications and using the expectation of relative difference of indication weights to express the relationship between pattern and grade order, permitting the unequality of the numbers of standard objects of various grades) introducing two indexes of the evalued objects—favorability and information completeness, the former expressing the favorable degree of mineralization of the object and the latter expressing the completeness of data of the object. Finally, the article introduces a practical example of using the improved logic-information method to manage the mineral forecast.

文章在实践经验的基础上,进一步阐发了逻辑信息法原理,介绍了为扩大方法适用性所作的各种改进。包括详细讨论逻辑信息法对一个标志所赋权值的两个方面。第一方面表征一个标志的构形与等级变化之间的关系,称为标志权相对差。第二方面说明一个标志在和其它标志联合起来区分不同等级标准对象中的作用大小,称为信息权。对方法的改进有:将标志的两种状态扩充为三态,允许个别对象个别标志缺失资料;用标志正负构形出现概率之差来筛选标志,用标志权相对差期望来表征构形与等级)顺序的关系,允许不同等级标准对象数不等;引入评价对象的两种指标有利度和信息度,前者说明对象的成矿有利程度,后者说明对象资料完备情况。最后列举了一个用改进的逻辑信息法处理的矿产预测实际例子。

The paper has analysed and discussed the calculating processes of the method of the logic information,the principles to distingush the defferent markers of the targets,the stable features of the model and the calculated method of the marking information weight. Geological effects of the method have been also studied by these calculating results through the method for prospecting gold-placer in the north of Huma county in Heilnogjiang province.
