摘要 范例推理的关键步骤在于相似范例的检索,而范例库中的特征项权重起到重要的作用。文章讨论了用遗传算法来获取范例库上的特征项权重,并用两种改进的遗传算法来发现范例库上的特征项权重,给出了具体的算法,分析了实验结果。该方法可用于权重发现。 In case-based system, the retrieval of similar cases is the key step of the intelligent system, and the attribute weighting of a case base takes important effect. This paper introduces two improved GAs to find the attribute weights, and analyzes the experimental results. This method can be used for weights finding.
