Large margin strategies in machine learning

2000 IEEE International Symposium on Circuits and Systems. Emerging Technologies for the 21st Century. Proceedings (IEEE Cat No.00CH36353), 2002
Controlling the capacity of a learning system in a way that does not depend on the dimensionality of the hypothesis space provides the key for effectively using large neural networks and decision trees, ensemble methods and kernel-induced feature spaces.

Voltage stability margin prediction by ensemble based extreme learning machine

2013 IEEE Power & Energy Society General Meeting, 2013
Voltage stability margin (VSM) evaluation is one of the essential tasks of power system voltage stability analysis. Conventional methods for VSM calculation is based on continuation-power flow technique. Recently, there is growing interest to apply artificial neural network (ANN) techniques to rapidly predict the VSM.

Associating machine-learning and analytical models for quality of transmission estimation: combining the best of both worlds

IEEE\/OSA Journal of Optical Communications and Networking, 2021
By associating machine learning and an analytical model (i.e., the Gaussian noise model), we reduce uncertainties on the output power profile and the noise figure of each amplifier in an optical network. We leverage the signal-to-noise ratio (SNR) of all

Large-Margin Label-Calibrated Support Vector Machines for Positive and Unlabeled Learning

IEEE Transactions on Neural Networks and Learning Systems, 2019
Positive and unlabeled learning (PU learning) aims to train a binary classifier based on only PU data. Existing methods usually cast PU learning as a label noise learning problem or a cost-sensitive learning problem. However, none of them fully take the data distribution information into consideration when designing the model, which hinders them from ...
