In underdetermined blind source separation problems, it is common practice to exploit the underlying sparsity of the sources for demixing. In this work, we propose two sparse decom...
There are numerous mechanisms for separation of concerns at the source code level. Three mechanisms that are the focus of recent attention – metadata annotations, pointcuts and a...
This paper examines some questions concerning commercial computer security integrity policies. We give an example of a dynamic separation of duty policy which cannot be implemente...
Given a pair of nonidentical complex objects, de ning and determining how similar they are to each other is a nontrivial problem. In data mining applications, one frequently nee...
Partially supervised segmentation, that is, segmentation with always incomplete training data has many practical applications in image analysis and retrieval. This paper proposes a...
