| Abstract: | Objective To predict the surival time of hepatoma patients.Method The BP neural network method.Results The network was set up and used to predict the survival time.For the training data,the contributing proportion of the predicting of the network is 86 85%,the mean error rate is 11 43%,for general data,those are 61 66% and 13 81% respectively.Conclusion The BP neural network can be used to predict the survival time of hepatoma patients.It is preferable and should be used further. |
