Global Nonlinear Kernel Prediction for Large Data Set With a Particle Swarm-Optimized Interval Support Vector Regression

A new global nonlinear predictor with a particle swarm-optimized interval support vector regression (PSO-ISVR) is proposed to address three issues (viz., kernel selection, model optimization, kernel method speed) encountered when applying SVR in the presence of large data sets. The…

A high-order Brillouin frequency shifter and its application in MBEFL

By employing one-order Brillouin frequency shifter to nest a two-order one, a three-order Brillouin frequency shifter is formed. A triple-Brillouin-frequency spaced multiwavelength Brillouin-erbium fiber laser (MBEFL) is experimentally demonstrated by incorporating the Brillouin frequency shifter into a ring cavity.
