Abstract:
K-Means is the most popular of clustering method, but its drawback is sensitivity to outliers. This paper discusses the addition of the outlier removal method to the K-Means method to improve the performance of clustering. The outlier removal method was added to the Local Outlier Factor (LOF). LOF is the representative outlier’s detection algorithm based on density. In this research, the method is called LOF K-Means.

Abstract As a representative type of outlier, abnormal data in displacement measurement has often inevitably occurred in full-field optical metrology and significantly affected further evaluation, especially when calculating the strain field by differencing the displacement. In this study, an outlier removal method is proposed which can recognize and remove the abnormal data in an optically measured displacement field. An iterative critical factor least squares (CFLS) algorithm is developed which distinguishes the distance between the data points and the least squares plane to identify the out

Abstract:
Data streams online modeling and prediction is an important research direction in the field of data mining. In practical applications, data streams are often of nonstationary nature and containing outliers, hence an online learning algorithm with dynamic tracking capability as well as anti-outlier capability is urgently needed. With this in mind, this paper proposes a novel robust adaptive online sequential extreme learning machine (RA-OSELM) algorithm for the online modeling and prediction of nonstationary data streams with outliers.

Abstract:
Up-to-date digital photogrammetry involves operations on huge data sets, and with classical image processing procedures it might be time consuming to find out the best solution. One of the key tasks is to detect outliers in given data, eg for curve fitting or image matching. The problem is hard as the number of outliers is usually large, possibly larger than 50%, thus powerful estimation techniques are needed. We demonstrate one of these techniques, namely Random Sample Consensus (RANSAC), for fitting a model to sample data, especially for fitting a straight line through a set of given points.

Abstract:
Recently, the broad learning system (BLS) has been widely developed in virtue of its excellent performance and high-computational efficiency. However, two deficiencies still exist in BLS and preclude its deployment in real applications. First, the standard BLS performs poorly in outlier environments because the least squares loss function it uses to train the network is sensitive to outliers. Second, the model structure of BLS is likely to be redundant since the hidden nodes in it are randomly generated. To address the above two issues, a new robust and compact BLS (RCBLS), based on M-estimato

Networks are ubiquitous. We start our technical work in this thesis by exploring the classical concept of node centrality (also known as influence measure) in information networks. Like clustering, node centrality is also an ill-posed problem. There exist several heuristics and algorithms to compute the centrality of a node in a graph, but there is no formal definition of centrality available in the network science literature. Lately, researchers have proposed axiomatic frameworks for the centrality of a node in a network. However, these existing formal frameworks are not generic in nature in

Abstract:
Ireland’s Women in Finance Charter is an initiative to address gender imbalances in the sector, by supporting firms’ initiatives to improve their female representation. Created in 2022, the Charter now counts 81 signatories. Together these firms employ over 63,428 workers, representing just over half of employees in the sector. Therefore, the changes undertaken by the signatory firms have the potential to significantly influence the opportunities available to women working in the Irish financial sector. This is the second annual Ireland’s Women in Finance Charter report. It outlines the progre

Abstract:
Mepsy is CLASP’s appliance and equipment climate impact calculator. It’s designed for policymakers, researchers, and other industry stakeholders to model different policy scenarios and measure their impact. Mepsy uses a “bottom-up” accounting approach, considering the number of appliances in use in a country, the energy performance of representative products, the climate-intensity of the local power grid, and other variables to analyze the electricity use, carbon dioxide emissions, and consumer energy costs associated with a given policy scenario. Wherever possible, the calculator references p

Abstract:
This paper looks at the technical issues associated with the representation of Theories of Change and the implications of design choices for the evaluability of those theories. The focus is on the description of connections between events, rather the events themselves, because this is seen as a widespread design weakness. Using examples and evidence from Internet sources six structural problems are described, along with their consequences for evaluation. The paper then outlines a range of different ways of addressing these problems, which could be used by programme designers, implementers and

Abstract:
Expeditionary airfield matting systems are lightweight, portable surfaces that enable the rapid deployment of infrastructure to support aircraft operations. Individual matting components are assembled via interlocking joints to construct arrays that serve as temporary aircraft operating surfaces. The paper outlines the homogenization of the AM2 portable airfield matting system and its interlocking mechanisms to permit computationally efficient analyses toward understanding mechanisms that influence the global behavior of these arrays and underlying subgrade during aircraft maneuvers.

Abstract:
The development of robust public water and sanitation policies requires dependable, transparent, and representative data; however, the available datasets for the region are complex with indicators that are often misinterpreted by policy professionals. It is essential that users understand the strengths and limitations of these datasets to facilitate source choice and ensure that their use results in accurate insights. This document discusses and contrasts water and sanitation access data produced by three sources: the WHO/UNICEF Joint Monitoring Programme for Water Supply, Sanitation and Hygie

Abstract:
The COVID-19 pandemic has disrupted the education of over 1.5 billion students globally. A majority of students live in countries where schools were either fully closed or were operational only through remote access. As school disruptions are likely to have lasting impacts on children’s human capital accumulation, data documenting how schools and households have adapted to this new learning environment have the potential to provide information on how to curb the adverse effects of school closures on children’s educational progress.

Abstract:
Citizen science is an umbrella term that describes a variety of ways in which members of the public can participate in science. The main characteristics of the approach are that: citizens are actively involved in research, in partnership or collaboration with scientists or professionals; and there is a genuine outcome, such as new scientific knowledge, conservation action or policy change. Citizen science involves communities participating in data collection or analysis, or other kinds of collaboration, like co-creating research questions and interpreting data. The approach, endorsed by the Eu
