Modeling Multiple Tasks In Recommendation Systems, Dinh Hieu Do

Dissertations and Theses Collection (Open Access)

Traditional research in recommendation systems has largely centered on the static offline supervised learning setting. In this paradigm, all available user-item interaction data is collected and partitioned into fixed training, validation, and test sets. Models are developed and evaluated in this controlled environment, where the underlying data distribution is assumed to remain unchanged. This approach offers clear advantages: it simplifies experimentation, enables reproducible benchmarking, and allows for straightforward comparisons between algorithms.

However, this static offline setting does not reflect the realities faced by modern recommendation systems. In real-world applications, data is dynamic and ever-evolving, where new users and items are …

Calibrated Structures Of Feeling: Cultural Citizenship And The Reproduction Of The Military In Singapore, John Lowe, George Wong

Research Collection School of Social Sciences

This article discusses the nexus between Raymond Williams’ structure of feelings and the reproduction of military masculinity as cultural citizenship. By placing the gaze upon National Service in the Singapore Armed Forces as a rite of passage into manhood, this work uses representations of the military in popular culture and souvenirs/ephemera to elucidate how structures of feeling are calibrated as masculinity the state wants its citizenry to internalize. These render military masculinity emergent for Singaporean male bodies. With the male body functioning as an important edifice of the military, emotions toward military service are the connective tissue between enactments of …

Language Brokering Conditions The Indirect Association Between Mexican‐Origin Adolescents' Academic Discrimination And Educational Expectations, Su Yeong Kim, Yayu Du, Chantal Alvarado, Wei Xiang Sim, Wen Wen, Tianlu Zhang, Jingyi Shen

Research Collection School of Social Sciences

Mexican-origin adolescents, a significant portion of the US Latino population, often experience a decline in educational expectations from early to late adolescence. Contextual factors such as academic discrimination and language brokering for parents may contribute to this decline. This study investigates the indirect effect of academic discrimination experienced in middle school on educational expectations in young adulthood through high school grades and engagement, and the moderating role of language brokering experiences in these relations. Data were collected from 604 Mexican-origin adolescents across four waves from 2012 to 2023. Academic discrimination experiences in middle school were negatively associated with school grades …

Artificial Insights Or Historical Fidelity? Crafting An Ethical Framework For The Use Of Genai In The Restoration, Reconstruction And Recreation Of Movable Cultural Heritage, David Ocón, Chunzhi Yin, Jose Luna

Research Collection School of Social Sciences

This article explores the ethical considerations surrounding using Generative Artificial Intelligence (GenAI) in preserving movable cultural heritage, focusing specifically on its application in restoration, reconstruction, and recreation. While GenAI offers innovative methods for preserving and recreating cultural heritage, it also presents significant ethical challenges. The article reviews current studies on the role of GenAI in heritage preservation alongside relevant ethical guidelines and proposes a tailored ethical framework for its application in movable heritage. The framework addresses several critical ethical concerns, including cultural integrity and sensitivity, accuracy and authenticity, intellectual property rights, sustainability and social impact, and governance and ethical accountability. …

Diaspora By Another Name: The Making Of Refugees In Cold War China, Jiaqi M. Liu, Clare Xiaoqian Wan

Research Collection School of Social Sciences

By examining China’s refugee policies from 1949 to 1982, this article demonstrates how the Chinese state redefined “return” and “refugee” to serve shifting political objectives. While China is often perceived as a source, rather than a host, of asylum seekers, it hosted over 320,000 displaced migrants—primarily ethnic Chinese from Southeast Asia—during the Cold War. Through a systematic discourse analysis of 382 People’s Daily articles, we identify four state narratives—diaspora, diplomatic tool, ideological sanctuary, and legal duty—that structured how China labeled displaced migrants, interpreted their sentiments, and determined their settlement. These models evolved dynamically: from the 1950s to the late 1970s, …

Not Staying Regular?, Joshua Thong

Research Collection School of Social Sciences

Consider the following claims: 1. Rational credences are real-valued. 2. A rational agent is more confident in than in just in case appropriate set-theoretic relations between the relevant events and/or appropriate inequalities between her numerical credences, whether conditional or not, hold. 3. If a rational agent’s conditional credence in, given, is greater than her conditional credence in, given, then she is more confident in than in. 4. There are two distinct and particular ways of ordering the events in a lottery over the naturals, for each of which there exists a rational agent whose comparative confidence ordering corresponds to that …

Governing Migration, Producing Skills: Emigration And Education In The Philippines, Yasmin Y. Ortiga, Roderick. Galam

Research Collection School of Social Sciences

This article examines skill as an integral yet understudied aspect of emigration governance. To date, migration studies have mainly focused on how the demand for migrant skills drive people's movements across borders, shaping the conditions for entry into popular destinations in the West. In contrast, less is known as to how skills also shape the way governments manage emigration, pushing would-be migrants to acquire certain capacities well before they leave their countries of origin. Drawing from the case of the Philippines, this article discusses how state agencies have used skills training to dominate specific markets for migrant professionals and demand …

Stockpiling, Forecasting And Protecting Skills: Skilling As Technique Of Preparedness In Times Of Crises, Rebecca Ye, Yasmin Y. Ortiga

Research Collection School of Social Sciences

In this comparative and situational analysis, we examine how nation-states use skilling as a technique of preparedness during crisis moments. By analysing two strategically selected country cases, Singapore and Sweden, during a critical phase of a global pandemic, we identify three techniques: stockpiling, forecasting, and protecting skills, and how these were enacted as a means to perform preparedness. Stockpiling skills was observed to take place as a rapid response; forecasting skills was a technique enacted with a view on the longer-term horizon and protecting skills was mobilised as a short-term future technique, where boundaries were assembled around skilling. While there …

Religious Beliefs, Cooperation, And Evolutionary Mechanisms, Nicole Fellice Ko, Norman P. Li

Research Collection School of Social Sciences

Religion is an organized system of spiritual beliefs, practices, and rituals that often involve a sense of the divine (Schilbrack, 2022). An evolutionary mechanism is an evolved set of traits that interpret environmental inputs and generate behavioral responses that enhance survival or reproductive success (Li et al., 2018). Cooperation refers to the act of individuals or groups working together to achieve a shared goal or mutual benefit (Alós-Ferrer & Garagnani, 2020).

A Power Dependence Model Of The Impact Of Leader Impostorism On Supervisor Support And Undermining: The Moderating Role Of Power Distance, Zihan Liu, Zihan Liu, Feng Qiu, Keith Leavitt, Xingyu Wang, Ziyang Tang

Research Collection Lee Kong Chian School Of Business

Leaders, often perceived as possessing exceptional confidence and competence, are not immune to feelings of self-doubt. Leader impostorism describes the experience that one’s attributes, experiences, skills, and abilities fall short of the standards expected in the leadership role, resulting in a sense of deception in fulfilling leadership responsibilities. While existing research has examined the antecedents and individual outcomes of leader impostorism, its implications for leaders’ treatment of subordinates remain largely unexplored. In this research, we investigate the downstream consequences of leader impostorism on behaviors directed toward subordinates. Integrating research on leader impostorism with power dependence theory, we propose that for …

Analyzing Google Maps As A Data Source For Urban Research In Dhaka, Xinyi Du

Dissertations and Theses Collection (Open Access)

This paper investigates how mass transit infrastructure shapes urban economic activity by examining the impact of Dhaka's first metro line using novel Google Maps data. Leveraging the opening of Metro Line 6 on December 2022, we employ a difference-in-differences framework to analyze changes in business establishment density around metro stations. Our estimates show that every 1% reduction in distance to the nearest metro station adds, on average, about 0.092–0.111 establishments per 40 m × 40 m grid cell—that is, roughly 57 – 69 additional businesses per square kilometer. The effect is even more pronounced for dining: about 1 – 4 …

Dissertations and Theses Collection (Open Access)

Dementia is a neurodegenerative disease with a prevalence rate expected to triple by 2050, posing a significant challenge for health services. To impede the increasing prevalence, medical professionals and scientists are actively investigating technology to detect cognitive decline at a reversible stage known as Mild Cognitive Impairment (MCI). Digital biomarker technology is an emerging pragmatic approach to permit objective, ecologically valid, and long-term continuous measurement of cognitive health status, rendering it as one of the promising technologies for early MCI detection. Despite its potential, it is nontrivial to encode, extract and combine predictive information from these digital biomarker technologies; advanced …

Do Search Costs Explain Persistent Investment In Active Mutual Funds?, Aljoscha Janssen, Jurre Thiel

Research Collection School Of Economics

Active funds, though losing market share since the 1990s, make up nearly half of all mutual funds but charge more without better performance. We analyze fund data and a search model, highlighting the impact of search costs and active fund preferences. From 1993 to 2018, reduced search costs expanded the market and heightened competition, while a preference shift from active to passive funds increased the latter's market share. However, investors who choose active funds, facing higher search costs, and continue to show a strong preference for them, allow these funds to keep charging higher fees.

An On-The-Fly Synthesis Framework For Ltl Over Finite Traces, Shengping Xiao, Yongkang Li, Shufang Zhu, Jun Sun, Jianwen Li, Geguang Pu, Moshe Vardi

Research Collection School Of Computing and Information Systems

We present an on-the-fly synthesis framework for Linear Temporal Logic over finite traces (LTLf) based on top-down deterministic automata construction. Existing approaches rely on constructing a complete Deterministic Finite Automaton (DFA) corresponding to the LTLf specification, a process with doubly exponential complexity relative to formula size in the worst case. In this case, the synthesis cannot be conducted until the entire DFA is constructed. This inefficiency is the main bottleneck of existing approaches. To address this challenge, we first present a method for converting LTLf into Transition-based DFA (TDFA) by directly leveraging LTLf semantics, incorporating intermediate results as direct components …

Query Understanding In Llm-Based Conversational Information Seeking, Yifei Yuan, Zahra Abbasiantaeb, Mohammad Aliannejadi, Yang Deng

Query understanding in CIS involves accurately interpreting user intent through context-aware interactions. This includes resolving ambiguities, refining queries, and adapting to evolving information needs. LLM enhance this process by interpreting nuanced language and adapting dynamically, improving the relevance and precision of search results in real-time. In this tutorial, we explore advanced techniques to enhance query understanding in LLM-based CIS systems. We delve into LLM-driven methods for developing robust evaluation metrics to assess query understanding quality in multi-turn interactions, strategies for building more interactive systems, and applications like proactive query management and query reformulation. We also discuss key challenges in integrating …

High Frequency Factor Analysis With Partially Observable Factors, Dachuan Chen, Wenqi Lu, Siyu Xie

Research Collection School Of Economics

This paper considers a novel factor structure – Partially Observable Factor Model – where both observable factors and latent factors exist in the model simultaneously. Such factor structure can make sure both interpretability and goodness-of-fit at the same time. Necessary estimation methodologies for this partially observable factor model are developed in this paper for the high frequency data. The proposed estimation methodology is robust to jumps, microstructure noise and asynchronous observation times simultaneously.When the observable factors are exogenous, we provide the estimation theory for the integrated eigenvalues of the residual covariance matrix, which including the bias-corrected estimator, central limit theorem …

The Role Of Private Law In Promoting Building Safety: The Case Of Singapore, Edward S. W. Ti

Research Collection Yong Pung How School Of Law

Singapore is a tiny granite rock situated just north of the equator. Lacking land, and indeed any kind of natural resource, means that the trend for urban development in the city-state will always be densifi cation; 96 per cent of residents in Singapore already live in multi-owned housing, ie high-rise apartments. 1 Singapore is also a rapidly greying nation. 2 It has been observed that persons over 70 years old are four times more vulnerable in the event of a fi re, 3 and fi re safety is a critical aspect of building safety. Safety features and measures in the …

The Basic Structure In Malaysia: Less Than Meets The Eye, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

At first glance, studying the basic structure doctrine in Malaysia can be frustrating due to its inconsistent judicial treatment. While early cases such as Loh Kooi Choon and Phang Chin Hock rejected the doctrine, it was later accepted in landmark decisions like Sivarasa Rasiah, Semenyih Jaya, and Indira Gandhi. In 2020, scholars such as Jaclyn Neo and Yvonne Tew suggested a judicial embrace of the doctrine and its global trend toward constitutional unamendability. However, the Federal Court’s 2021 decision in Maria Chin Abdullah appeared to reject it once more, illustrating the doctrine’s precarious status. The resurgence seen in Dhinesh a/l …

Digital Economy Innovation In The Indo-Pacific: Towards A 'Singapore Effect'?, J.G. Allen, Qiu Xu Martin Liao

Research Collection Yong Pung How School Of Law

This paper examines the rise of Digital Economy Agreements (DEAs) in the Indo-Pacific as a strategic response to digital trade fragmentation and great power competition. Focusing on Singapore’s leadership, we introduce the ‘Singapore Effect’ – a model of regulatory influence distinct from others, such as the ‘Brussels Effect’ and ‘Beijing Effect.’ Unlike market-driven regulatory diffusion, the Singapore Effect emphasizes interoperability, norm entrepreneurship, and mini-lateralism, enabling middle powers to shape digital trade governance. We analyze DEA formation, implementation challenges in national law, and Singapore’s role as a bridge between diverse regulatory regimes. DEAs’ flexible, modular structure allows for incremental regulatory alignment …

Operationalising The Social Licence To Operate Along The Belt And Road: The Case For A Mediation-Focused Approach, Mark Mclaughlin

Research Collection Yong Pung How School Of Law

This article examines the intricate dynamics of community representation and stakeholder influence in the realm of international investment law. More specifically, it considers the most effective method by which to operationalise the concept of the ‘social licence to operate’ when attempting to resolve investor-state disputes. By utilising disputes relating to China’s Belt and Road Initiative as a case study, it is shown that the social impact of foreign investment projects is often a catalyst for arbitration claims. Community interests are insufficiently represented at the stage of procurement or admission of investment, which has led to violent clashes between investors and …

Wild Hogs In The Water: Contested Infrastructural Ecologies Of Reservoir Storage In Texas, Sayd Randle

Research Collection College of Integrative Studies

Reservoirs are developed to store water in reserve for future use. But once built, reservoir sites inevitably hold more than just water, often serving as a key habitat for a range of species. This paper examines how one such animal has transformed water storage facilities and nearby landscapes into contested ground in urbanising areas of Texas, USA. Living around the reservoirs, feral hogs complicate the process of urbanisation by degrading the stockpiled water and infrastructure at the storage sites themselves and by damaging private property throughout the surrounding landscape. Tracking local efforts to manage the hogs, the case study illustrates …

Political Ecologies Of Storage For The 21st Century, Sayd Randle, Matthew Archer

Research Collection College of Integrative Studies

New resource storage arrangements are proliferating rapidly both in terms of physical infrastructures-for the storage of things like "clean" energy, nuclear waste, carbon dioxide, fresh water, and data-and as part of a set of discursive moves that reinforce a vision of a near future world in which problems of climate change mitigation and adaptation in particular (but also issues like energy security, water security, industry growth, etc.) are solved through eco-modernist techno-fixes. This Symposium sketches the contours of a framework we term political ecologies of storage. In doing so, we treat storage as both a potent imaginary and a concrete …

Sensor Lag Adjustments On A Mobile Meteorological Cart In Tropical Environments: A Case Study From An Urban Park In Singapore, Moshe Eliezer Mandelmilch, Sin Kang Yik, Beatrice H. Ho, Graces N. Y. Ching, Peter J. Crank, Winston T. L. Chow

Research Collection College of Integrative Studies

This study adds to the growing literature on mobile platforms by examining the performance of the Singapore MaRTy (SMaRTy) in conducting mobile micrometeorological measurements along a designated route in an urban park in Singapore, reflecting a pedestrian walking experience. The main objective of the study was to calculate the sensor lag for the mobile climate measurements: Air Temperature (TA), and Relative Humidity (RH) of SMaRTy along a designated route in an urban park in Singapore based on data from fixed stations (HOBO sensors) in two significant synoptic meteorological periods during the Northeast and Southwest monsoons. Statistically significant regression models were …

The Miseducation Of Model Minorities: The Gospel Of ‘Schoolvation’ And The Myth Of The Schooled Society, Justin Kh Tse

Research Collection College of Integrative Studies

The ‘model minority’, the phenomenon of some ‘minority’ communities (or some members within them) achieving social and economic advancement despite encountering the difficulties of assimilating into a mainstream society, is often described as a myth, especially as one of the central problematics in Asian American studies. Usually, the modern use of the word myth is pejorative: the model minority in this sense refers to a false empirical description of some minorities and should be quantitatively disaggregated and qualitatively debunked. In this article, I want to explore the model minority as another kind of myth, in the classical sense of mythos, …

A New City For A New Era: Xiong'an As Showcase Of China's Evolving Urban Ideology, Andrew Stokols

Research Collection College of Integrative Studies

Cities have long been expressions of political ideology in China and elsewhere. During China’s rapid urbanization over the past few decades, “new areas” became popular strategies to promote urban growth, following the success of Shenzhen, widely regarded as China’s first special economic zone. Today under Xi, Xiong’an New Area has become the latest “new area of national significance.” But unlike previous new areas in China, Xiong’an has become wedded to a distinct vision of the urban in Xi Jinping’s China, one in which the excesses of reform-era urbanization are controlled through new forms of affordable housing and finance, new ecological …

An Incentive Mechanism For Privacy Preserved Data Trading With Verifiable Data Disturbance, Man Zhang, Xinghua Li, Bin Luo, Yanbing Ren, Yinbin Miao, Ximeng Liu, Robert H. Deng

Research Collection School Of Computing and Information Systems

To motivate data owners’ (DOs’) trading willingness, the existing incentive mechanisms allow DOs to independently disturb data following data consumer's (DC’s) availability requirement. However, they cannot motivate DOs’ honest disturbance, which is attributed to DOs’ independent disturbance without any supervision. Thus, we implement an incentive mechanism for privacy preserved data trading with verifiable data disturbance where an honest-but-curious disturbance generator (DG) is additionally introduced to supervise DOs’ local disturbance and assist disturbance verification between DOs and DC. Specifically, DG generates the disturbance strategies and secretly distributes to DOs following private information retrieval, guaranteeing DOs's local disturbance's privacy and verifiability with …

An Exponential Cone Integer Programming And Piece-Wise Linear Approximation Approach For 0-1 Fractional Programming, Hoang Giang Pham, Thuy Anh Ta, Tien Mai

Research Collection School Of Computing and Information Systems

We study a class of binary fractional programs commonly encountered in important application domains such as assortment optimization and facility location. These problems are known to be NP-hard to approximate within any constant factor, and existing solution approaches typically rely on mixed-integer linear programming or second-order cone programming reformulations. These methods often utilize linearization techniques (e.g., big-M or McCormick inequalities), which can result in weak continuous relaxations. In this work, we propose a novel approach based on an exponential cone reformulation combined with piecewise linear approximation. This allows the problem to be solved efficiently using standard cutting-plane or branch-and-cut procedures. …

Position: Trustworthy Ai Agents Require The Integration Of Large Language Models And Formal Methods, Yedi Zhang, Yufan Cai, Xinyue Zuo, Xiaokun Luan, Kailong Wang, Zhe Hou, Yifan Zhang, Zhiyuan Wei, Meng Sun, Jun Sun, Jing Sun, Jin Song Dong

Research Collection School Of Computing and Information Systems

Large Language Models (LLMs) have emerged as a transformative AI paradigm, profoundly influencing broad aspects of daily life. Despite their remarkable performance, LLMs exhibit a fundamental limitation: hallucination—the tendency to produce misleading outputs that appear plausible. This inherent unreliability poses significant risks, particularly in high-stakes domains where trustworthiness is essential. On the other hand, Formal Methods (FMs), which share foundations with symbolic AI, provide mathematically rigorous techniques for modeling, specifying, reasoning, and verifying the correctness of systems. These methods have been widely employed in mission-critical domains such as aerospace, defense, and cybersecurity. However, the broader adoption of FMs remains constrained …

Llmscan: Causal Scan For Llm Misbehavior Detection, Mengdi Zhang, Kai Kiat Goh, Peixin Zhang, Jun Sun, Lin Xin Rose, Hongyu Zhang

Research Collection School Of Computing and Information Systems

Despite the success of Large Language Models (LLMs) across various fields, their potential to generate untruthful and harmful responses poses significant risks, particularly in critical applications. This highlights the urgent need for systematic methods to detect and prevent such misbehavior. While existing approaches target specific issues such as harmful responses, this work introduces LLMSCAN, an innovative LLM monitoring technique based on causality analysis, offering a comprehensive solution. LLMSCAN systematically monitors the inner workings of an LLM through the lens of causal inference, operating on the premise that the LLM’s ‘brain’ behaves differently when generating harmful or untruthful responses. By analyzing …
