In an unreliable communication network, failures may occur to nodes and/or links. The problem of finding a source for data broadcast on the network can be reduced to the problem of computing a most reliable source of the network. Previous studies focused on the case of either edge failures or node failures. In this paper, we study a more general case, where each node has an independent transmitting...
Stepping-stone attack in network intrusion detection are attackers who use a sequence of intermediate (or so called stepping-stone) hosts to initiate attacks in order to hide their origins. We investigate a number of dynamic programming based pattern recognition approaches and our novel algorithm for detecting correlation and similarity of two connections not only into and out of a single stepping...
We study video attention by detecting a salient object sequence from video segment. We formulate salient object sequence detection as energy minimization problem in a conditional random field framework, while static and dynamic salience, spatial and temporal coherence, global topic model are well defined and integrated to identify a salient object sequence. Dynamic programming algorithm is designed...
Most organizations do not have sufficient resources to meet all of their obligations; selecting which projects should be funded is not just ranking projects and funding them 'top-down' until resources are depleted. Organizations need to balance the benefits that project portfolios provide with their respective constraints and they need to do so in a meaningful way. To address this problem, we propose...
Summary form only given. Most organizations do not have sufficient resources to meet all of their obligations; selecting which projects should be funded is not just ranking projects and funding them 'top-down' until resources are depleted. Organizations need to balance the benefits that project portfolios provide with their respective constraints and they need to do so in a meaningful way. To address...
