چکیده

We derive a one-period look-ahead policy for finiteand infinite-horizon online optimal learning problems with Gaussian rewards. The resulting decision rule easily extends to a variety of settings, including the case where our prior beliefs about the rewards are correlated. Experiments show that the KG policy performs competitively against other learning policies in diverse situations. In the case where the optimal policy is known, the KG policy performs comparably well, while being substantially more convenient to use.

Online Streaming Feature Selection Using Geometric Series of the Adjacency Matrix of Features

Feature Selection (FS) is an important pre-processing step in machine learning and data mining. All the traditional feature selection methods assume that the entire feature space is available from the beginning. However, online streaming features (OSF) are an integral part of many real-world applications. In OSF, the number of training examples is fixed while the number of features grows with t...

A New Fuzzy Stabilizer Based on Online Learning Algorithm for Damping of Low-Frequency Oscillations

A multi objective Honey Bee Mating Optimization (HBMO) designed by online learning mechanism is proposed in this paper to optimize the double Fuzzy-Lead-Lag (FLL) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. The proposed double FLL stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...

The effect of language complexity and group size on knowledge construction: Implications for online learning

This  study  investigated  the  effect  of  language  complexity  and  group  size  on  knowledge construction in two online debates. Knowledge construction was assessed using Gunawardena et al.’s Interaction Analysis Model (1997). Language complexity was determined by dividing the  number  of  unique  words  by  total  words.  It  refers  to  the  lexical  variation.  The  results showed  that...

An Adaptive Gradient Method for Online AUC Maximization

Learning for maximizing AUC performance is an important research problem in machine learning. Unlike traditional batch learning methods for maximizing AUC which often suffer from poor scalability, recent years have witnessed some emerging studies that attempt to maximize AUC by single-pass online learning approaches. Despite their encouraging results reported, the existing online AUC maximizati...
