We consider the broad framework of supervised learning, where one gets examples of objects together with some labels (such as tissue samples labeled as cancerous or non-cancerous, or images of handwritten characters labeled with the correct character in a-z), and the goal is to learn a prediction model which given a new object, makes an accurate prediction. The notion of accuracy depends on the...

Surrogate-based-optimization methods provide a means to minimize expensive highfidelity models at reduced computational cost. The methods are useful in problems for which two models of the same physical system exist: a high-fidelity model which is accurate and expensive, and a low-fidelity model which is less costly but less accurate. A number of model management techniques have been developed ...

Business data are subject to change by time or by the modifications of business rules. New knowledge needs to be extracted to reflect the most up to date situations hence periodic or occasional re-mining is essential. This paper proposes an active multidimensional association mining framework that incorporates with user preference ontology, which contains surrogate queries that represent freque...

This study proposes a novel framework based on magnitude cumulant and surrogate analyses to reliably detect the presence of intermittency and estimate the intermittency coefficient from short-length coarse-resolution turbulent time series. Intermittency coefficients estimated from a large number of neutrally stratified atmospheric surface layer turbulent series from various field campaigns are ...

Distributed mobile systems are characterized by asymmetry in both network connectivity and computing power, mobility of hosts and their constraints. To address these issues, existing approaches attempt to completely redesign distributed applications or algorithms to make them work in a distributed mobile environment. This paper proposes an alternate mechanism namely, the surrogate object model ...

In this paper, we propose a framework for wireless/mobile pervasive computing to augment capabilities and to save scanty resources of mobile host by making full use of available resources in the surrounding. Firstly, a mobile device finds and utilizes the cheap computer as a surrogate to forward the service requests. Secondly, after the surrogate discovers the services, it will filter, synthesi...
