A Spherical Hidden Markov Model for Semantics-Rich Human Mobility Modeling
We study the problem of modeling human mobility from semantic trace data, wherein each GPS record in a trace is associated with a text message that describes the user’s activity. Existing methods fall short in unveiling human movement regularities for such data, because they either do not model the text data at all or suffer from text sparsity severely. We propose SHMM, a multi-modal spherical ...
متن کاملIntrusion Detection Using Evolutionary Hidden Markov Model
Intrusion detection systems are responsible for diagnosing and detecting any unauthorized use of the system, exploitation or destruction, which is able to prevent cyber-attacks using the network package analysis. one of the major challenges in the use of these tools is lack of educational patterns of attacks on the part of the engine analysis; engine failure that caused the complete training, ...
متن کاملSemantics-based Dynamic Hypermedia Adaptation using the Hidden Markov Model
Information collection, selection, structuring, and presentation design are the core considerations for general hypermedia presentation generation systems. The content collection process can be enhanced by retrieving semantically related information objects, relevant to the topic selected by an author. Once relevant information objects are available, the content selection process suggests seman...
متن کاملModeling Context Aware Dynamic Trust Using Hidden Markov Model
Modeling trust in complex dynamic environments is an important yet challenging issue since an intelligent agent may strategically change its behavior to maximize its profits. In this paper, we propose a context aware trust model to predict dynamic trust by using a Hidden Markov Model (HMM) to model an agent’s interactions. Although HMMs have already been applied in the past to model an agent’s ...
متن کاملtuberculosis surveillance using a hidden markov model
background: routinely collected data from tuberculosis surveillance system can be used to investigate and monitor the irregularities and abrupt changes of the disease incidence. we aimed at using a hidden markov model in order to detect the abnormal states of pulmonary tuberculosis in iran. methods: data for this study were the weekly number of newly diagnosed cases with sputum smear-positive p...
