- 在根据网络学习的特点、建立网络学习评价系统指标体系的基础上,提出利用模糊熵理论评价网络学习效果的模型。 该模型通过熵权法对各评价指标权重进行修正得到客观权重值,并与主观权重结合计算出综合权重,然后利用模糊理论进 行处理得到综合评价值,改善了传统评价方法主观因素影响过多的弊端,提高了评价结果的可信度,并实验验证了该方法 的可行性和正确性,确保了网络学习评价公平公正地进行。-In accordance with the characteristics of learning, netwo

LVQ
- 该评估问题实际上是一个分类问题,评价指标作为网络的输入,评估等级是网络的输出,CPN网络的竞争层能够进行聚类,再通过有导师学习就可以精确划分类型,在该例中获得了成功的应用。 从此例中也可以发现,随着样本数得增多,网络的训练次数也随之增加,另外,该例中隐层节点数的选择还主要依靠经验和试验。 由本实验的结果可知,利用CPN神经网络实现博士论文评价具有很好的效果,其评价结果与专家所给结果基本一致。-The evaluation problem is actually a classificat
