We show that the survivable bottleneck Steiner tree problem in normed planes can be solved in polynomial time when the number of Steiner points is constant. This is a fundamental problem in wireless ad-hoc network design where the objective is to design networks with efficient routing topologies. Our result holds for a general definition of survivability and for any norm whose ball is specified...
Experiments in which laboratory populations of fruitflies have been repeatedly passed through bottlenecks fail to support 'founder-effect' models of speciation.
We propose a neural network framework for highdimensional conditional density estimation. The Bottleneck Conditional Density Estimator (BCDE) is a variant of the conditional variational autoencoder (CVAE) that employs layer(s) of stochastic variables as the bottleneck between the input x and target y, where both are high-dimensional. The key to effectively train BCDEs is the hybrid blending of ...
Bottleneck features have been shown to be effective in improving the accuracy of automatic speech recognition (ASR) systems. Conventionally, bottleneck features are extracted from a multi-layer perceptron (MLP) trained to predict context-independent monophone states. The MLP typically has three hidden layers and is trained using the backpropagation algorithm. In this paper, we propose two impro...
in this paper, the weighted szeged indices of cartesian product and corona product of twoconnected graphs are obtained. using the results obtained here, the weighted szeged indices ofthe hypercube of dimension n, hamming graph, c4 nanotubes, nanotorus, grid, t− fold bristled,sunlet, fan, wheel, bottleneck graphs and some classes of bridge graphs are computed.
assessing genetic biodiversity and population structure of minor populations through the information provided by neutral molecular markers, allows determination of their extinction risk and to design strategies for their management and conservation. analysis of microsatellite loci is known to be highly informative in the reconstruction of the historical processes underlying the evolution and di...
Bottleneck detection in manufacturing is the key to improving production efficiency and stability in order to improve capacity. Yet common bottleneck detection methods in industry and academia lack either accuracy or practicability, or both, for dynamic systems. The new methodology is conducted by the observation of processes and inventories. Blocked processes and full inventories indicate a do...
Based on the accumulation of genetic, climatic, and fossil evidence, a central theory in paleoanthropology stipulates that a demographic bottleneck coincided with the origin of our species Homo Sapiens. This theory proposes that anatomically modern humans--which were only present in Africa at the time--experienced a drastic bottleneck during the penultimate glacial age (130-190 kya) when a cold...
In many cases, optimal operation for a plant is the same as maximum throughput. In this case a rigorous model for the plant is not necessary if we are able to identify the bottleneck. Optimal operation is the same as maximum throughput in the bottleneck. If the bottleneck does not move, this can be realized with singleloop controller from the throughput manipulator to the bottleneck. However, i...
