Negatively Correlated Bandits∗
We analyze a two-player game of strategic experimentation with two-armed bandits. Each player has to decide in continuous time whether to use a safe arm with a known payoff or a risky arm whose likelihood of delivering payoffs is initially unknown. The quality of the risky arms is perfectly negatively correlated between players. In marked contrast to the case where both risky arms are of the sa...
متن کاملNegatively Correlated Echo State Networks
Echo State Network (ESN) is a special type of recurrent neural network with fixed random recurrent part (reservoir) and a trainable reservoir-to-output readout mapping (typically obtained by linear regression). In this work we utilise an ensemble of ESNs with diverse reservoirs whose collective read-out is obtained through Negative Correlation Learning (NCL) of ensemble of Multi-Layer Perceptro...
متن کاملSimultaneous Learning of Negatively Correlated Neural Networks
A new approach to designing neural network ensembles has been proposed recently 1]. Experimental studies on some regression tasks have shown that the new approach performs signiicantly better than previous ones 1]. This paper presents a new algorithm for designing neural network ensembles for classiication problems with noise. This new algorithm is different from that used for regression tasks ...
متن کاملNegatively Correlated Neural Networks for Classi cation
A new approach to designing neural network ensembles has been proposed recently 1]. Experimental studies on some regression tasks have shown that the new approach performs signiicantly better than previous ones 1]. However, the regression tasks considered did not include any noise. This paper presents a new algorithm for designing neural network ensembles for classiication problems with noise. ...
متن کاملApproximation Algorithms for Correlated Knaspacks and Non-Martingale Bandits
In the stochastic knapsack problem, we are given a knapsack of size B, and a set of jobs whose sizes and rewards are drawn from a known probability distribution. However, the only way to know the actual size and reward is to schedule the job—when it completes, we get to know these values. How should we schedule jobs to maximize the expected total reward? We know constant-factor approximations f...
