Unraveling The Dynamics Of Stable And Curious Audiences In Web Systems, Rodrigo Alves, Antoine Ledent, Renato Assunção, Pedro Vaz-De-Melo, Marius Kloft

Research Collection School Of Computing and Information Systems

We propose the Burst-Induced Poisson Process (BPoP), a model designed to analyze time series data such as feeds or search queries. BPoP can distinguish between the slowly-varying regular activity of a stable audience and the bursty activity of a curious audience, often seen in viral threads. Our model consists of two hidden, interacting processes: a self-feeding process (SFP) that generates bursty behavior related to viral threads, and a non-homogeneous Poisson process (NHPP) with step function intensity that is influenced by the bursts from the SFP. The NHPP models the normal background behavior, driven solely by the overall popularity of the …

Aligning Human And Computational Coherence Evaluations, Jia Peng Lim, Hady Wirawan Lauw

Research Collection School Of Computing and Information Systems

Automated coherence metrics constitute an efficient and popular way to evaluate topic models. Previous work presents a mixed picture of their presumed correlation with human judgment. This work proposes a novel sampling approach to mining topic representations at a large scale while seeking to mitigate bias from sampling, enabling the investigation of widely used automated coherence metrics via large corpora. Additionally, this article proposes a novel user study design, an amalgamation of different proxy tasks, to derive a finer insight into the human decision-making processes. This design subsumes the purpose of simple rating and outlier-detection user studies. Similar to the …

Container Runtime Systems (CRSs), which form the foundational infrastructure of container clouds, are critically important due to their impact on the quality of container cloud implementations. However, a comprehensive understanding of the quality issues present in CRS implementations remains lacking. To bridge this gap, we conduct the first comprehensive empirical study of CRS bugs. Specifically, we gather 429 bugs from 8,271 commits across dominant CRS projects, including runc, gvisor, containerd, and cri-o. Through manual analysis, we develop taxonomies of CRS bug symptoms and root causes, comprising 16 and 13 categories, respectively. Furthermore, we evaluate the capability of popular testing approaches, …

Cluster-Wide Task Slowdown Detection In Cloud System, Feiyi Chen, Yingying Zhang, Lunting Fan, Yuxuan Liang, Guansong Pang, Qingsong Wen, Shuiguang Deng

Research Collection School Of Computing and Information Systems

Slow task detection is a critical problem in cloud operation and maintenance since it is highly related to user experience and can bring substantial liquidated damages. Most anomaly detection methods detect it from a single-task aspect. However, considering millions of concurrent tasks in large-scale cloud computing clusters, it becomes impractical and inefficient. Moreover, single-task slowdowns are very common and do not necessarily indicate a malfunction of a cluster due to its violent fluctuation nature in a virtual environment. Thus, we shift our attention to cluster-wide task slowdowns by utilizing the duration time distribution of tasks across a cluster, so that …

Diverse Pathways To Permanent Childlessness In Singapore: A Latent Class Analysis, Yanwen Wang, Bussarawan Teerawichitchainan, Christine Ho

Research Collection School Of Economics

The proportions of adults reaching midlife without having children have been rising rapidly across the globe, particularly in Asia. However, little is known about the pathways to permanent childlessness within the region’s childless population. This study utilized latent class analysis (LCA) to typologize pathways to childlessness based on dynamic characteristics of multiple life domains (i.e., partnership, education, and occupation) among 489 childless Singaporeans aged 50 and above from a 2022 nationwide survey. Additionally, we utilized multinomial logistic regressions to examine the sociodemographic correlates of pathway profiles and Shannon’s entropy index to assess the heterogeneity in pathways to childlessness among successive …

Sin In Business: The Contributions Of Perversion, Defilement, And Idolatry, Jason M. Stansbury

University Faculty Publications and Creative Works

Far from being a parochial concern with the ritual observances of the faithful, sin is the fundamental problem of life for all people. It encompasses all of the violations of the peace that a person has or should have with God, themselves, others, and even the natural environment. These violations occur as people pervert parts of God’s good creation away from their created purposes and toward unworthy ones, disrupting the interdependent order of creation and defiling themselves and their objects in the process. It moreover is self-reinforcing, gaining a power over people that makes future sins more difficult to resist, …

2020-Current year OA Pubs

BACKGROUND: A major challenge in learning rhinoplasty is correlating patients' external and internal nasal structures. We aim to explore the application of three dimensional (3D)-printed models of nasal bony-cartilaginous structures in identifying accurate nasal anatomy.

METHODS: Otolaryngology-head and neck surgery and plastic and reconstructive surgery residents matched patient photograph models, described relative nasal bony-cartilaginous anatomy, completed pre- and postactivity self-evaluations (based on otolaryngology "nasal deformity" milestones including "anatomy," "function," "aesthetic," and "etiology"), and rated the 3D-printed models' usefulness. Descriptive statistics were measured.

RESULTS: Thirty-seven residents correctly matched four of six model-photograph pairs and correctly described 15 of 30 anatomic relationships, …

The exchange of goods along the land-based and maritime routes, which inform Xi Jinping's Belt and Road Initiative, also …

Translation As Creative Writing: Rewriting The Chinese Maze Murders In Contemporary China, Xiaoquan Raphael Zhang

CLCWeb: Comparative Literature and Culture

In his article “Translation as Creative Writing: Rewriting The Chinese Maze Murders in Contemporary China,” Xiaoquan Raphael Zhang examines four groups of selected writings centered on one of Robert van Gulik’s more well-known Judge Dee novels, The Chinese Maze Murders (written first in English but not published until 1956). Different from most publications on van Gulik and his novels, Zhang examines the impact of censorship and self-censorship on the writing, rewriting, and (re)adapting, “literal” and “liberal/free” translation of the Judge Dee stories traveling between Chinese and English, between China and the West, for Chinese and non-Chinese audiences. Focus is given …

Precarious Refugee: Self-Optimization And Neoliberal Rationality In Rawi Hage’S Cockroach, Shahab Nadimi

CLCWeb: Comparative Literature and Culture

In his article "Precarious Refugee: Self-Optimization and Neoliberal Rationality in Rawi Hage’s Cockroach," Shahab Nadimi examines Rawi Hage’s Cockroach as an example of refugee literature in the light of current debates about neoliberal biopolitics and the idea of a new form of life. Refugees, who are neither identified as citizens nor totally as strangers, are forced to compete in unequal circumstances of economic mobility with other citizens, often leaving them in a condition of personal debts, unemployment, and mental distress. Nadimi investigates Cockroach’s depiction of psychological breakdown, suicidal attempts, and metamorphosis as symptomatic of and critical to the neoliberal …

Multi-Label Classification Using Conformal Prediction, Chhavi Tyagi

Dissertations

In many machine learning applications, such as image tagging, document classi-fication, and medical diagnosis, a data instance can be associated with multiple classes in parallel so that each instance is associated with multiple response variables simultaneously defining multi-label classification. Standard multi-label classification methods that provide point predictions have been developed. They lack in quantifying the uncertainty of predictions. These methods also lack in accounting for label dependencies and are very computationally expensive. This dissertation develops two methods of multi-label classification using conformal prediction that quantify the uncertainty of predictions. Chapter 1 introduces notations and tools that have been used in …

A Micromagnetic Study Of Skyrmions In Thin-Film Multilayered Ferromagnetic Materials, Nicholas J. Dubicki

Dissertations

Magnetic skyrmions are topologically protected, localized, nanoscale spin textures in non-centrosymmetric thin ferromagnetic materials and heterostructures. At present they are of great interest to physicists for potential applications in information technology due to their particle-like properties and stability. In a system of multiple thin ferromagnetic layers, the stray field interaction was typically treated with various simplifications and approximations. It is shown that extensive analysis of the micromagnetic equations leads to an exact representation of the stray field interaction energy in the form of layer interaction kernels, a so-called 'finite thickness' representation. This formulation reveals the competition between perpendicular magnetic anisotropy …

Settling Dust, Unsettling Ground, Olivia Newroz

Masters Theses

Understanding dust as a material system that blurs the line between ground and atmosphere, I developed a dust machine as a tool for making dust legible at the human scale. While the blurriness of ground is visualized at both particle and planetary scales, at the human scale, it becomes less evident. Drawing from Lisa’s Moffitt’s discussion of “environmental models”–that is, models that don’t merely simulate phenomena, in this case dust, but rather produce the underlying force itself––I produced visualizations of how dust, as both a grounded and atmospheric element, intertwines ground and weather across scales, through a cyclical process of …
