IEEE/ACM Transactions on Audio, Speech and Language Processing (TASLP), Volume 22, Issue 10Pages 1533–1545https://doi.org/10.1109/TASLP.2014.2339736Recently, the hybrid deep neural network (DNN)- hidden Markov model (HMM) has been shown to significantly improve speech recognition performance over the conventional Gaussian mixture model (GMM)-HMM. The performance improvement is partially attributed ...

The effect of expanding relevance judgements with duplicates
SIGIR '14: Proceedings of the 37th international ACM SIGIR conference on Research & development in information retrievalPages 1159–1162https://doi.org/10.1145/2600428.2609534We examine the effects of expanding a judged set of sentences with their duplicates from a corpus. Including new sentences that are exact duplicates of the previously judged sentences may allow for better estimation of performance metrics and enhance ...

Generalized Max Pooling
CVPR '14: Proceedings of the 2014 IEEE Conference on Computer Vision and Pattern RecognitionPages 2473–2480https://doi.org/10.1109/CVPR.2014.317State-of-the-art patch-based image representations involve a pooling operation that aggregates statistics computed from local descriptors. Standard pooling operations include sum- and max-pooling. Sum-pooling lacks discriminability because the resulting ...

Space-Time Robust Representation for Action Recognition
ICCV '13: Proceedings of the 2013 IEEE International Conference on Computer VisionPages 2704–2711https://doi.org/10.1109/ICCV.2013.336We address the problem of action recognition in unconstrained videos. We propose a novel content driven pooling that leverages space-time context while being robust toward global space-time transformations. Being robust to such transformations is of ...

Call-type dependence in multiskill call centers
The effect on multiskill call-center performance of pooling dependent call types is investigated. For this purpose, a copula-based modeling approach is used to provide multivariate models that take into account the call types' asymmetric dependence ...

Threshold and majority group testing
Information Theory, Combinatorics, and Search TheoryJanuary 2013, Pages 488–508We consider two generalizations of group testing: threshold group testing (introduced by Damaschke [11]) and majority group testing (a further generalization, including threshold group testing and a model introduced by Lebedev [20]).
We show that each ...

On real-time ad-hoc retrieval evaluation
SIGIR '12: Proceedings of the 35th international ACM SIGIR conference on Research and development in information retrievalPages 1119–1120https://doi.org/10.1145/2348283.2348498Lab-based evaluations typically assess the quality of a retrieval system with respect to its ability to retrieve documents that are relevant to the information need of an end user. In a real-time search task however users not only wish to retrieve the ...

Quantile Scores for Combining Results from Different Microarray Platforms
OCCBIO '09: Proceedings of the 2009 Ohio Collaborative Conference on BioinformaticsPages 135–138https://doi.org/10.1109/OCCBIO.2009.16Due to the small number of replicates in typical gene microarray experiments, the performance of statistical inference is often unsatisfactory. In this article, we present a scoring scheme, based on quantiles, that allows researchers to combine data ...

A Pooling Analysis of Two Simultaneous Online Auctions
Manufacturing & Service Operations Management (INFORMS-MSOM), Volume 11, Issue 1Pages 33–51https://doi.org/10.1287/msom.1070.0192Motivated by the ease with which online customers can bid simultaneously in multiple auctions, we analyze a system with two competing auctioneers and three types of bidders: those dedicated to either of the two auctions and those that participate ...
