Adaptive dynamic programming (ADP) is a promising research field for design of intelligent controllers, which can both learn on-the-fly and exhibit optimal behavior. Over the past decades, several generations of ADP design have been proposed in the literature, which have demonstrated many successful applications in various benchmarks and industrial applications. While many of the existing researches...
Co-training is a semi-supervised learning technique used to recover the unlabeled data based on two base learners. The normal co-training approaches use the most confidently recovered unlabeled data to augment the training data. In this paper, we investigate the co-training approaches with a focus on the diversity issue and propose the diversity of class probability estimation (DCPE) co-training approach...
In this paper, we analyze a class of actor-critic algorithms under partially observable Markov decision process (POMDP) environment. Specifically, in this work we focus on the two-time-scale framework in which the critic uses a temporal difference with neural network (NN) as nonlinear function approximator, and the actor is updated using greedy algorithm with the stochastic gradient approach. Instead...
In this paper, we present the research of a foreign currency investment framework involving the prediction of the foreign currency exchange rates and the portfolio optimization under certain constrains. We adopt two machine learning methods, support vector machines (SVMs) and neural networks (NNs), as well as the traditional moving average method, to predict the exchange rates for three foreign currencies...
