| Abstract: |
| The paper proposed a multi-target synthetic evaluation system of high sci-tech agriculture projects based on neural network,and established risk evaluation model of high sci-tech agriculture projects based on BP neutral network.The network model was trained and predicted by using the factual examples.The results show that back-propagation network model can carry on the work according to the experts' methods,which provides the risk control forecasting tool for the agricultural high sci-tech investment projects and demonstrates that the neutral network model has broad application prospects in the modern economical non-linear domain. |
| Key words: BP neutral network high sci-tech agriculture project risk evaluation |
