In accordance with the problem that the fcm algorithm is quite time - consuming for search out cluster cancroids and may not be suitable for on - line modeling and control . this dissertation proposed an improved fuzzy identification method based multistage random sampling fuzzy c - means clustering algorithm ( mrfcm ) . it has higher approximate precision and the cpu time has slowed down sharply compared with the common fuzzy Johnyen和liangwang介紹了幾種應用于模糊模型的信息優化準則,本論文在此基礎上對統計信息準則進行一些改進,并與快速模糊聚類和正交最小二乘方法結合,提高了模型的辨識精度和泛化能力。

This paper adopts an adaptive learning algorithm based on hierarchy clustering to update user profile , which continuously abstract the cancroids of one class of optimum information from the feedback flow of system , which effectively shield the learning process from plenty of feedback noises produced by distorted threshold and sparseness of initial information , which also can imitate artificial feedback approximately to perfect the intelligence of adaptive learning mechanism 摘要本文采用一種基于層次聚類的自適應學習策略,從系統反饋的信息流中,動態提取一類最優信息的質心更新用戶模型,有效屏蔽了閾值失真和初始信息稀疏造成的大量反饋噪聲,并且能夠近似模仿人工反饋,完善自適應學習機制的智能性。

Bone tumor is a common bone disease , its category includes benign tumor , malignant tumor , metastasis tumor , cancroid pathological changes , and etc . , it ' s usually seen in juvenile and does many harms 骨腫瘤是一種常見的骨科疾病,有良性、惡性、轉移癌及癌樣病變等,多發于青少年,危害較大。
