Abstract: This paper uses the learning algorithm of feedforward neural networks based on the regularized least squares on the knowledge discovery on time series databases. The algorithm improves the generalization performance of feedforward neural networks through combining the regularization and pruning technology. It demonstrates the method on the temporal rule discovery of stock market time series database. The process of knowledge discovery includes preprocessing of time series data and data mining (rule discovery). The experiment demonstrates the effectiveness of the algorithm.
