  • Term Frequency Normalisation Tuning for BM25 and DFR Models

    سند علمی۲۰۰۵ECIRBen He, Iadh Ounis

    The term frequency normalisation parameter tuning is a crucial issue in information retrieval (IR), which has an important impact on the retrieval performance. The classical pivoted normalisation approach suffers from the collection-dependence problem. As a consequence, it requir

  • A Study of the Effects of Score Normalisation Prior to Fusion in Biometric Authentication Tasks

    سند علمی۲۰۰۴Norman Poh, Samy Bengio

    Although the subject of fusion is well studied, the effects of normalisation prior to fusion are somewhat less well investigated. In this study, four normalisation techniques and six commonly used fusion classifiers were examined. Based on 24 (fusion classifiers) as a result of p

  • Strong Normalisation in the π-Calculus

    سند علمی۲۰۰۱Nobuko Yoshida, Martin Berger, Kohei Honda

    We introduce a typed π-calculus where strong normalisation is ensured by typability. Strong normalisation is a useful property in many computational contexts, including distributed systems. In spite of its simplicity, our type discipline captures a wide class of converging name-p

  • Hyper Normalisation and Conditioning for Discrete Probability Distributions

    سند علمی۲۰۱۷Logical Methods in Computer ScienceBart Jacobs

    Normalisation in probability theory turns a subdistribution into a proper distribution. It is a partial operation, since it is undefined for the zero subdistribution. This partiality makes it hard to reason equationally about normalisation. A novel description of normalisation is

  • Can masticatory electromyography be normalised to submaximal bite force?

    سند علمی۲۰۱۵Journal of oral rehabilitationS R Crawford, A M Burden, J M Yates, P Zioupos

    The combination of bite force and jaw muscle electromyography (EMG) provides an insight into the performance of the stomatognathic system, especially in relation to dynamic movement tasks. Literature has extensively investigated possible methods for normalising EMG data encapsula

  • Spectral bi-normalisation for speech recognition in additive noise

    سند علمی۲۰۰۳MAVEBACarlos Lima, Jorge Oliveira

    The changing on peaks structure of the speech spectrum is perhaps the most important cause of degradation of speech recognition systems under adverse conditions. Another drawback concerned to the additive noise effect occurs on the flat spectral zones which are usually raised pro

  • Normalisation in Weakly Orthogonal Rewriting

    سند علمی۱۹۹۹RTAVincent van Oostrom

    A rewrite sequence is said to be outermost-fair if every outer-most redex occurrence is eventually eliminated. Outermost-fair rewriting is known to be (head-)normalising for almost orthogonal rewrite systems. In this paper we study (head-)normalisation for the larger class of wea

  • DNA microarray normalisation, PCA and a related latent variable model

    سند علمی۲۰۰۱M. Rattray, N. Morrison, D. Hoyle

    We study the effects of DNA microarray data pre-processing and normalisation. Our main methodology involves the comparison of results produced by a Principal Components Analysis under different treatments. We compare different normalisation strategies and parameterisations, and w

  • Constructing Normalisers in Finite Soluble Groups

    سند علمی۱۹۸۸J. Symb. Comput.Stephen P. Glasby

    This paper describes algorithms for constructing a Hall n-subgroup H of a finite soluble group G and the normaliser No(H). If G has composition length n, then H and No(H ) can be constructed using O(n ~ log IGI) and O(n ~ log IGI) group multiplications, respectively. These algori

  • Reference gene identification for reliable normalisation of quantitative RT-PCR data in Setaria viridis

    سند علمی۲۰۱۸Plant methodsDuc Quan Nguyen, Andrew L. Eamens, Christopher P. L. Grof

    Background Quantitative real-time polymerase chain reaction (RT-qPCR) is the key platform for the quantitative analysis of gene expression in a wide range of experimental systems and conditions. However, the accuracy and reproducibility of gene expression quantification via RT-qP
