....; C t (x) is the final outcome. The effectiveness of stacking to increase accuracy has been widely reported [4, 14, 15] Stacking is also a feasible approach to learn over inherently distributed data [4] The idea of stacking has been deployed and implemented as agents to attack credit card fraud [13]. Experiments in different domains have shown accuracy increases from 0.5 to 3 over any of the combined base classifiers. In this paper, we will discuss a problem called conflicts that hinders the accuracy improvement of stacking. We propose and discuss some methods to solve it. Conflicts were ....

....4 shows that this approach works well. An important feature here is that each bank only exchanges its locally computed classifiers, and not their local data. Thus, we are able to demonstrate the principle that it is possible to share knowledge without disclosing data . 3 The JAM Architecture JAM [8] is architected as an agent based system, a distributed computing construct that is designed as an extension of OS environments. It is a distributed metalearning system that supports the launching of learning and meta learning agents to distributed database sites. JAM is implemented as a ....
