Pascal Challenge: Linear Support Vector Machines
Hsiang-Fu Yu
Video in druga učna gradiva
Oznake: computer science;machine learning;kernel methods;support vector machines
We participate in the linear SVM Track of the Pascal Large Scale Learning Challenge at ICML 2008. We consider the LIBLINEAR package, which can handle L1- and L2-loss linear SVMs. The L1-SVM solver implemented in LIBLINEAR employes a coordinate descent method to solve the dual problem. This method is ...

Large Linear Classification When Data Cannot Fit In Memory
Hsiang-Fu Yu
Video in druga učna gradiva
Oznake: computer science;pattern recognition
Recent advances in linear classification have shown that for applications such as document classification, the training can be extremely efficient. However, most of the existing training methods are designed by assuming that data can be stored in the computer memory. These methods cannot be easily a ...

Adaptive super-twisting sliding mode control of hydraulic servo actuator with nonlinear features and modeling uncertainties
Zhenshuai Wan, Yu Fu, Longwang Yue, Chong Liu
Izvirni znanstveni članek
Oznake: hydraulic servo actuators;nonlinear features;modeling uncertainties;super-twisting sliding mode control;
This study proposes a novel adaptive super-twisting sliding mode controller (ASTSMC) for hydraulic servo actuator with nonlinear features and modeling uncertainties. In the proposed method, an extended state observer (ESO) is utilized to estimate the value of lumped uncertainties. The core feature o ...
