摘　　要：针对腹膜透析充分性评价指标繁多,且有不少单项指标评价结果之间是不相容的特点,将文献[4]中的MART2网络应用到充分性评价当中,并进行了适当改进。对选取的透析充分性指标进行预理后输入网络,经过网络的自学习将其分成很多聚类区并计算每一聚类区的重心,再根据透析充分性评价标准判断聚类重心的透析充分性,当网络阈值很高时,重心的透析充分性可以代表该聚类区的透析充分性,这样可以根据患者数据落入聚类区的编号来判断患者的透析充分性。本算法充分利用了改进的MART2网络在处理集群数据分类问题的优越性,取得了良好的应用效果。Against the large number of assessment indices to the adequacy peritoneal dialysis and incompatibility of some indices, an intelligent assessment approach to the peritoneal dialysis adequacy based on MART2 （modified from ART2） network is proposed. After non-dimension and weighting preconditioning, the assessment indices were put to MART2 and sorted into many clusters. The center-of-gravity of each cluster was identified as adequacy or inadequacy according to the assessment criteria of dialysis adequacy, and the adequacy of each cluster could be determined by the adequacy of corresponding center-of-gravity when the network threshold was high. Finally, the peritoneal dialysis adequacy of each patient could be judged according to the adequacy of cluster to which the patients＇ indices belong. Experimental results demounstrate its effectiveness.
