Abstract |
|
|
| Aiming at the parameter optimization of least square support vector machine (LS-SVM), an improved quantum-behaved
particle swarm optimization (IQPSO) algorithm for LS-SVM parameter selection was proposed. Based on QPSO, the algorithm
optimizes particle initializing positions and improves solving speed and precision by sampling and linearizing methods. IQPSO LSSVM
model was test by test functions and was compared with QPSO LS-SVM model. Furthermore, it was applied to thread’s amount
setting of database server in an agricultural producing system. The results show that the proposed model has greater solving speed and
higher precision. It can meet the database’s load requirement by thread’s amount adjustment in agricultural producing system. |
