Discrete scales

Studies assessing rating scales are very common in psychology and related ﬁelds, but are rare in NLP. In this paper we assess discrete and continuous scales used for measuring quality assessments of computergenerated language. We conducted six separate experiments designed to investigate the validity, reliability, stability, interchangeability and sensitivity of discrete vs. continuous scales. We show that continuous scales are viable for use in language evaluation, and offer distinct advantages over discrete scales. ...

The discrete wavelet transform (DWT) algorithms have a firm position in processing of signals in several areas of research and industry. As DWT provides both octavescale frequency and spatial timing of the analyzed signal, it is constantly used to solve and treat more and more advanced problems. The DWT algorithms were initially based on the compactly supported conjugate quadrature filters (CQFs). However, a drawback in CQFs is due to the nonlinear phase effects such as spatial dislocations in multiscale analysis.

DWTs are constantly used to solve and treat more and more advanced problems. The DWT algorithms were initially based on the compactly supported conjugate quadrature filters (CQFs). However, a drawback in CQFs is due to the nonlinear phase effects such as spatial dislocations in multiscale analysis. This is avoided in biorthogonal discrete wavelet transform (BDWT) algorithms, where the scaling and wavelet filters are symmetric and linear phase. The biorthogonal filters are usually constructed by a laddertype network called lifting scheme.

Discrete wavelet transform (DWT) algorithms have become standard tools for discretetime signal and image processing in several areas in research and industry. As DWT provides both frequency and location information of the analyzed signal, it is constantly used to solve and treat more and more advanced problems. The present book: Discrete Wavelet Transforms: Theory and Applications describes the latest progress in DWT analysis in nonstationary signal processing, multiscale image enhancement as well as in biomedical and industrial applications....

The justiﬁcation for choosing this typing scheme is scalability. In other sys tems, such as one ﬁnds for example in the Java Distributed Event Speciﬁca tion [SunMicrosystems 1998] andCORBANotiﬁcation Service [ObjectManage ment Group 1998b], a notiﬁcation is a value of some named, explicit notiﬁcation type. This implies a global authority formanaging and verifying the type space, something which is clearly not feasible at an Internet scale. On the other hand, we deﬁne a restricted set of attribute types from which to construct (arbitrary) notiﬁcations.

THERMODYNAMIC MODELING, ENERGY EQUIPARTITION, AND NONCONSERVATION OF ENTROPY FOR DISCRETETIME DYNAMICAL SYSTEMS WASSIM M. HADDAD, QING HUI, SERGEY G. NERSESOV, AND VIJAYSEKHAR CHELLABOINA Received 19 November 2004 We develop thermodynamic models for discretetime largescale dynamical systems. Speciﬁcally, using compartmental dynamical system theory, we develop energy ﬂow models possessing energy conservation, energy equipartition, temperature equipartition, and entropy nonconservation principles for discretetime, largescale dynamical systems.

VECTOR DISSIPATIVITY THEORY FOR DISCRETETIME LARGESCALE NONLINEAR DYNAMICAL SYSTEMS WASSIM M. HADDAD, QING HUI, VIJAYSEKHAR CHELLABOINA, AND SERGEY NERSESOV Received 15 October 2003 In analyzing largescale systems, it is often desirable to treat the overall system as a collection of interconnected subsystems. Solution properties of the largescale system are then deduced from the solution properties of the individual subsystems and the nature of the system interconnections.

After the domination of behaviourism in AngloAmerican psychology during the middle of the century, the impression has been left, reflected in the many texts on research design, that the experimental method is the central tool of psychological research. In fact, a glance through journals will illuminate a wide array of datagathering instruments in use outside the experimental laboratory and beyond the field experiment.

SLEκ is a random growth process based on Loewner’s equation with driving parameter a onedimensional Brownian motion running with speed κ. This process is intimately connected with scaling limits of percolation clusters and with the outer boundary of Brownian motion, and is conjectured to correspond to scaling limits of several other discrete processes in two dimensions. The present paper attempts a ﬁrst systematic study of SLE. It is proved that for all κ = 8 the SLE trace is a path; for κ ∈ [0, 4] it is a simple path; for κ ∈ (4, 8) it is...

We present an analysis of boundedenergy lowtension maps between 2spheres. By deriving sharp estimates for the ratio of length scales on which bubbles of opposite orientation develop, we show that we can establish a ‘quantization estimate’ which constrains the energy of the map to lie near to a discrete energy spectrum. One application is to the asymptotics of the harmonic map ﬂow; we ﬁnd uniform exponential convergence in time, in the case under consideration.

This project measures and classifies language variation. In contrast to earlier dialectology, we seek a comprehensive characterization of (potentially gradual) differences between dialects, rather than a geographic delineation of (discrete) features of individual words or pronunciations. More general characterizations of dialect differences then become available. We measure phonetic (un)relatedness between dialects using Levenshtein distance, and classify by clustering distances but also by analysis through multidimensional scaling. ...
