Early stopping algorithm based on fuzzy clustering was put forward to solve this problem in this paper. Subtractive clustering and Fuzzy C-Means clustering (FCM) were combined to realize optimal division of training set  validation set and test set. How to realize this algorithm in backpropagation (BP) network by utilizing neural network toolbox and fuzzy logic toolbox in MATLAB was dwelled on. Early stopping algorithm based on fuzzy clustering and other early stopping algorithms were applied in function approximation and pattern recognition problems in validation experiments. Experiments results indicate that early stopping algorithm based on fuzzy clustering has higher precision in comparison to other early stopping algorithms. Outputs of training set  validation set and test set are more accordant. 2009 IEEE.   Optimal Stopping with Model Uncertainty and Pricing the American Option 会议论文 2nd International Conference on Business Intelligence and Financial Engineering, JUL 24-26, 2009 作者:  Zhao, Guoqing 收藏  |  浏览/下载：3/0  |  提交时间：2019/12/31 American put-option  optimal stopping  ambiguity  BSDE  g-expectation
