摘要/Abstract

摘要：

对原有的受单个参数控制的二维信息扩散方式作了改进，通过构造一个概率扩散模型导出了一个由3个参数控制的扩散函数，在此基础上根据实际情况建立一个准则，最终得到一个信息扩散的参数优化数学模型.实例表明在小样本的情况下，该最优信息扩散方法能够取得更加理想的结果.

关键词: 扩散函数, 小样本, 最优信息扩散

Abstract:

By improving the method for two-dimensional information diffusion that is governed by a single parameter, a new type of diffusion function is obtained. Based on the new diffusion function, an optimized parametric model is proposed for information diffusion under some criteria based on real situations. An example using the proposed method is given, which results in better results with a small sample.

Key words: diffusion function, optimal information diffusion, small sample
