Combining Partitions in SecSpaces
SecSpaces is a data-driven coordination model that supports a tuple-based coordination space extended with mechanisms for controlling and authenticating the access to entries. This is achieved exploiting the notion of (symmetric and asymmetric) abstract partitions inside the space. In this paper we consider one of the limitations of SecSpaces: it is not well suited for supporting the atomic acc...
متن کاملCombining Generalizers Using Partitions Of The Learning Set
Figure 1. A stylized depiction of how to combine the two generalizers G 1 and G 2 via stacked generalization. A learning set L is symbolically depicted by the full ellipse. We want to guess what output corresponds to the question q. To do this we create a CVPS of L; one of these partitions is shown, splitting L into {(x, y)} and {L-(x, y)}. By training both G 1 and G 2 on {L-(x, y)}, asking bot...
متن کاملCombining Fuzzy partitions Using Fuzzy Majority Vote and KNN
this paper firstly generalizes majority vote to fuzzy majority vote, then proposes a cluster matching algorithm that is able to establish correspondence among fuzzy clusters from different fuzzy partitions over a common data set. Finally a new combination model of fuzzy partitions is build on the basis of the proposed cluster matching algorithm and fuzzy majority vote. Comparative results show ...
متن کاملCluster Ensembles --- A Knowledge Reuse Framework for Combining Multiple Partitions
This paper introduces the problem of combining multiple partitionings of a set of objects into a single consolidated clustering without accessing the features or algorithms that determined these partitionings. We first identify several application scenarios for the resultant ‘knowledge reuse’ framework that we call cluster ensembles. The cluster ensemble problem is then formalized as a combinat...
متن کاملA formal approach for checking security properties in SecSpaces
SecSpaces is a Linda-like coordination model whose aim is to provide a support for secure coordination in Open System applications. Substantially it provides a methodology to restrict the access to the objects stored in the shared dataspace. In this paper we introduce a formal language for representing systems interacting via SecSpaces primitives and its operational semantics. Moreover in this ...
