Abstract

Supervised learning algorithm is widely used in current research of software project risks, while it cannot evaluate the risk without decision class. Considering this, we present an unsupervised model, which can solve the forecasting problem of outsourcing software projects risks in unsupervised situation, based on T-S fuzzy neural network (T-S FNN) and the concept of standard score in risk evaluation of outsourcing software project. In simulation, we use 200 samples to train and test the network repeatedly, helping us to get the accuracy rate of 76.2%. After that, the standard score of 0.558 is applied to the forecasting of 60 testing samples, and the accuracy of them is 75%, which shows the stability of the model. Moreover, the comparison with some supervised neural networks shows that the forecasting accuracy of T-S FNN is close to that of the supervised models above. Meanwhile, T-S FNN shows a more balanceable forecasting performance in both successful project and failure project.
