| 加权系数a 和b 分别用于控制正例项的项数和负例项的项数。先验知识中，当输入的信息出现在某类的概率大于某个阈值（实验中取为0.9），则正例项增加;当信息不可能出现在某类或出现在某类的概率小于某个某个阈值（实验中取为0.1），则负例项增加。 |

| The weighting coefficients a and b are the factors that respectively control the numbers of terms regarding to the positive cases and the negative cases. In the priori knowledge, when the probability of input informations occured in certain range exceeded threshold value (0.9 as set in the experiment), the positive case number will increase; while if the input information never occured in certain range or the possibility of input information occured in certain range is less than the threshold (0.1 as set in experiment), the negative case number will grow. |

| The weight coefficient of a and B are respectively used for Items Items Items control positive examples and negative example item. A priori knowledge, when the input information appears in a class of probability is greater than a certain threshold (in the experiment is 0.9), is an increase in cases of; when the information is not possible in a class or appear in a class probability less than a certain threshold (in the experiment is 0.1), then the negative cases an increase in. |
