These algorithms dynamically create and delete copies of shared data objects that can be read and written by the nodes in the network. Our algorithms aim to minimize the congestion, i.e., the maximum communication load over all network resources, so that that none of these resources become a communication bottleneck. We give several examples of networks for which our framework yields efficient algorithms, including meshes, fat-trees, hypercubic networks, and complete networks. For example, our framework yields an $O(d cdot log n)$-competitive caching algorithm for $d$-dimensional meshes of size $n$ with respect to the congestion on the communication links, and an $O(1)$-competitive algorithms for complete networks with respect to the congestion at the memory modules due to remote accesses. Previous work on data management in networks either neglects memory capacity constraints or minimizes only the total communication load, i.e., the sum of the communication load over all resources, which may produce congestion as some of the links become bottlenecks.}}, author = {{Meyer auf der Heide, Friedhelm and Vöcking, Berthold and Westermann, Matthias}}, booktitle = {{SODA '00: Proceedings of the eleventh annual ACM-SIAM symposium on Discrete algorithms}}, isbn = {{0898714532}}, pages = {{430–439}}, title = {{{Caching in networks}}}, year = {{2000}}, } @inbook{16497, author = {{Meyer auf der Heide, Friedhelm and Kutyłowski, Mirosław and Ragde, Prabhakar}}, booktitle = {{Euro-Par 2000 Parallel Processing}}, isbn = {{9783540679561}}, issn = {{0302-9743}}, title = {{{Complexity Theory and Algorithms}}}, doi = {{10.1007/3-540-44520-x_59}}, year = {{2000}}, } @inbook{16513, author = {{Aston, P.

Extensive recognition experiments have been conducted both on the standard TIMIT phone recognition task and on a proprietary 130-words command word task under various adverse environmental conditions, including reverberant data with real-life room impulse responses and data processed by acoustic echo cancellation algorithms. Significant error rate reductions have been achieved when applying the novel long-range feature filters compared to standard approaches employing cepstral mean normalization and delta and delta-delta features, in particular when facing acoustic echo cancellation scenarios and room reverberation.
