The purpose of this paper is twofold. Namely, to present a probabilistic analysis of a class of bottleneck (capacity) optimization problems, and to design simple and efficient heuristic algorithms guaranteed to be asymptotically optimal. OUf unified approach is applied to a wide variety of bottleneck problems including vehicle routing problems, location problems, and communication network probl...

Bottleneck features have been shown to be effective in improving the accuracy of speaker recognition, language identification and automatic speech recognition. However, few works have focused on bottleneck features for acoustic scene classification. This report proposes a novel acoustic scene feature extraction using bottleneck features derived from a Deep Neural Network (DNN). On the official ...

To realize maximum throughput, tight control of the bottleneck unit(s) is necessary. Dynamic degrees of freedom can be used to obtain tighter bottleneck control. Here, “dynamic” means that the degree of freedom has no steady-state effect on plant operation, like most inventories (levels). Nevertheless, temporary changes of inventories can allow for dynamic changes in the flow through the bottle...

Practice can, in some cases, largely eliminate measured dual-task interference. Does this absence of interference indicate the absence of a processing bottleneck (defined as an inability to carry out certain stages in parallel)? The authors show that a bottleneck need not produce any observable interference, provided that there is no temporal overlap in the demand for bottleneck stages on the 2...

A global definition of bottleneck degree is first proposed by introducing an exponential function, the value of bottleneck degree for each working station can be obtained through real time calculation and compared, based on which a new method of exponential dynamic bottleneck detection (EDBD) is presented. This method provides an efficient means for bottleneck detection. Experiments under light...
