Abstract

In this article, a just-in-time ADAPTIVE DISTANCE METRIC LEARNING for application in nonstationary environments is addressed. This generative model enables adaptive similarity-based classifiers to classify the time-labeled inquiry patterns which are coming from a nonparametric stochastic process with superior performance. Here, the performance points to accurately classification in low-dimensional feature space with minimum model adaptation during the system life time. While there are adaptive forms of feature extraction methods, which transform training patterns to a low-dimensional space and/or improve classifier accuracy, they are vulnerable to nonparametric changes in data and must continuously update their parameters. In the proposed method, an optimal transformation matrix transforms time-labeled instances from the original space to a new feature space to maximize the probability of selecting the correct class label for incoming instances using similarity-based classifiers. To this end, for a given time-labeled instance, nonparametric intra-class and extra-class distributions are proposed. The proposed method is also furnished to a temporal detector to provide the most convenient time for the adaptation phase. Experimental results on real and synthesized datasets that include real and artificial changes demonstrate the performance of the proposed method in terms of accuracy and dimension reduction in dynamic environments.
