Classification is a very broad and prevalent topic of research within data mining. Whilst heavily related, time series classification (TSC) offers a more specific challenge. One of the most promising approaches proposed for TSC is time series shapelets. In this paper we assess the current quality measure used for shapelet extraction and introduce two statistical tests into the context of shapel...

Over the past 10 years, several instruments developed specifically for the assessment of Quality of Life (QOL) in dementia have been introduced. The goal of the current review is to present, compare, and critique existing QOL measures for dementia populations to assist investigators and clinicians in selecting the optimal inventory for their specific needs. Nine measures are reviewed with a foc...

In the last few years a lot of new possibilities for the acquisition of terrain data were developed. Next to new developments in the area of digital photogrammetry due to automated image matching techniques, laserscanning has revolutionized the capturing of topographic data. For digital terrain models (DTMs) derived from “traditional” photogrammetric techniques accuracy measures, which were der...

Measuring voice quality for telephony is not a new problem. However, packet-switched, best-effort networks such as the Internet present significant new challenges for the delivery of real-time voice traffic. Unlike the circuit-switched public switched telephone network (PSTN), Internet protocol (IP) networks guarantee neither sufficient bandwidth for the voice traffic nor a constant, acceptable...

This report comprises chapters 2 to 5 of a report prepared for NASA on the applica-tion of software quality and assurance techniques to AI software [105]. The chaptersincluded here provide a review of software quality assurance techniques as appliedto conventional software. The techniques covered include software reliability andmetrics, static and dynamic testing, and formal...

Case base maintenance is one of the most important issues for current research in Case–Based Reasoning (CBR). In this paper, we outline two novel steps as part of the maintenance phase of the CBR process. The review step covers assessment and monitoring of the knowledge containers whereas the restore step actually modifies the contents of the containers according to recommendations resulting fr...

Fingerprint image quality is an important factor in the performance of Automatic Fingerprint Identification Systems(AFIS). It is used to evaluate the system performance, assess enrollment acceptability, and evaluate fingerprint sensors. This paper presents a novel methodology for fingerprint image quality measurement. We propose limited ring-wedge spectral measure to estimate the global fingerp...

Australian Bureau of Statistics This paper represents work in progress and does not necessarily reflect the final approach which the ABS will adopt. Executive Summary This paper reports work in progress on a project called Quality Measures for Systems of Economic Accounts (QMSEA). The distinctive features of QMSEA are that it-Is designed to review whether present and future systems of economic ...
