This paper considers additive factorial hidden Markov models, an extension to HMMs where the state factors into multiple independent chains, and the output is an additive function...
Many of today’s audiovisual application systems offer some kind of interactivity. Yet, quality assessments of these systems are often performed without taking into account the po...
The trend of the networking processing is to increase the intelligence of the routers (i.e. security capacities). This means that there is an increment in the workload generated p...
