Levenberg-Marquardt (shorted as L-M) algorithm is improved and adopted to train the neural network. The improved training algorithm leads to better convergence, faster convergent speed and higher precision. The proposed L-M neural network is used for geological data mining of oil productive index basing on the geological database. The process of geological spatial data mining and the geological knowledge...
Web database of geological information is constructed to manage the geological information efficiently. The infrastructure of the Web database is implemented with B/S model, where the geological information is classified into four types of entities and stored in the database with Microsoft SQL Server 2005.The Web server is implemented with Microsoft IIS and the exchange of the data between the Web...
