Larger Is Not Always Better: Exploring Small Open-Source Language Models In Logging Statement Generation, Renyi Zhong, Yichen Li, Guangba Yu, Wenwei Gu, Jinxi Kuang, Yintong Huo, Michael R. Lyu

Research Collection School Of Computing and Information Systems

Developers use logging statements to create logs that document system behavior and aid in software maintenance. As such, high-quality logging is essential for effective maintenance; however, manual logging often leads to errors and inconsistency. Recent methods emphasize using large language models (LLMs) for automated logging statement generation, but these present privacy and resource issues, hindering their suitability for enterprise use. This paper presents the first large-scale empirical study evaluating small open-source language models (SOLMs) for automated logging statement generation. We evaluate four prominent SOLMs using various prompt strategies and parameter-efficient fine-tuning techniques, such as Low-Rank Adaptation (LoRA) and Retrieval-Augmented Generation …

Multicbr: Multi‑View Contrastive Learning For Bundle Recommendation, Yunshan Ma, Yingzhi He, Xiang Wang, Yinwei Wei, Xiaoyu Du, Yuyangzi Fu, Tat‑Seng Chua

Research Collection School Of Computing and Information Systems

Bundle recommendation seeks to recommend a bundle of related items to users to improve both userexperience and the profits of platform. Existing bundle recommendation models have progressed from capturing only user-bundle interactions to the modeling of multiple relations among users, bundles, and items.CrossCBR, in particular, incorporates cross-view contrastive learning into a two-view preference learningframework, significantly improving SOTA performance. It does, however, have two limitations: (1) the twoview formulation does not fully exploit all the heterogeneous relations among users, bundles, and items; and(2) the “early contrast and late fusion” framework is less effective in capturing user preference and difficultto generalize to …

Train In Vain: Functionality-Preserving Poisoning To Prevent Unauthorized Use Of Code Datasets, Yuan Xiao, Yuchen Chen, Jiaming Wang, Wei Song, Jun Sun, Shiqing Ma, Yanzhou Mu, Juan Zhai, Chunrong Fang, Jin Song Dong, Zhenyu Chen

Research Collection School Of Computing and Information Systems

The widespread availability of large-scale code datasets has accelerated the development of code large language models (CodeLLMs), raising concerns about unauthorized dataset usage. Dataset poisoning offers a proactive defense by reducing the utility of such unauthorized training. However, existing poisoning methods often require full-dataset poisoning and introduce transformations that break code compilability. In this paper, we introduce FunPoison, a functionality-preserving poisoning approach that injects short, compilable weak-use fragments into executed code paths. FunPoison leverages reusable statement-level templates with automatic repair and conservative safety checking to ensure side-effect freedom, while a type-aware synthesis module preserves type correctness, suppresses static-analysis warnings, and …

Itimo: An Llm-Empowered Synthesis Dataset For Travel Itinerary Modification, Zhuoxuan Huang, Yunshan Ma, Hongyu Zhang, Hua Ma, Zhu Sun

Research Collection School Of Computing and Information Systems

Addressing itinerary modification is crucial for enhancing the travel experience as it is a frequent requirement during traveling. However, existing research mainly focuses on fixed itinerary planning, leaving modification underexplored due to the scarcity of shape need-to-modify itinerary data. To bridge this gap, we formally define the itinerary modification task and propose a general pipeline to construct the corresponding dataset, namely iTIMO. This pipeline frames the generation of shape need-to-modify itinerary data as an intent-driven perturbation task. It instructs large language models to perturb real-world itineraries using three operations: REPLACE, ADD, and DELETE. Each perturbation is grounded in three intents: …

Semantic Context Improvisational Retrieval-Augmented Generation For Empathic Conversational Ai, Sharjeel Tahir, Judith Johnson, Jumana Abu-Khalaf, Syed Afaq Ali Shah

Research outputs 2022 to 2026

A fundamental limitation of modern conversational AI is its limited capacity to demonstrate sustained empathy in long-form interactions. We propose SCIRAG (Semantic Context Improvisational Retrieval-Augmented Generation), a feedback-driven retrieval framework for adaptive empathic dialogue. It employs a dual-loop retrieval framework, iteratively optimizing a static counseling dataset through user metadata and feedback memory refinement. To enhance contextual alignment, we deploy retrieval adaptation, enabling the model to retain and leverage past conversational cues based on user preferences. When integrated with Mixtral-8x7B, SCIRAG improves human-rated empathic understanding by +1.26 points and empathic response by +1.00 point on the RoPE scale, while increasing acceptability …

All Decisions

In this illegal sublet holdover in a rent-stabilized apartment, the court granted the tenant's motion to dismiss the petition because the predicate notice to cure and the notice of termination were impermissibly vague and devoid of factual details. The court found that the allegations in the predicate notices did not identify with reasonable specificity the conduct complained of, the dates and times, the persons involved, or the circumstances giving rise to the allegations, leaving respondents to speculate as to the factual basis of petitioner's claims and depriving them of a meaningful opportunity to cure and prepare an adequate defense.

An Emergent Seafood Nationalism Takes Hold In The United States, Owen Temby

School of Earth, Environmental, & Marine Sciences Faculty Publications

This paper introduces the concept of ‘seafood nationalism’ to describe how, since 2024–2025, the United States increasingly uses tariffs, trade remedies, food safety enforcement and origin-based rules to favour American seafood over foreign products. Federal actions include Executive Order 14276, Restoring American Seafood Competitiveness, which directs agencies to address unfair trade practices, unsafe imports and to develop a coordinated seafood trade strategy. Additional measures include a tariff package imposing a 10% duty on nearly all seafood imports and 30% on seafood from China, as well as new anti-dumping and countervailing duty orders on warm-water shrimp. This paper presents Gulf …

Not Just A Migraine: Transverse Venous Sinus Stenosis Presenting As Orthostatic Headache, Tejaswini Swamy, Aun A. Bangash, Chloe Harris, Jose E. Campo Maldonado

School of Medicine Publications

Transverse venous sinus stenosis (TVSS) is an underrecognized cause of intracranial hypertension that can mimic primary headache disorders. We report a woman with obesity and prior bariatric surgery who developed bifrontal headache with pulsatile tinnitus, dizziness, and visual blurring for 1 year. Orthostatic features and lack of response to therapy prompted further evaluation. Lumbar puncture revealed an opening pressure of 32 cm H2 O with immediate relief after cerebrospinal fluid removal. Magnetic resonance venography demonstrated severe TVSS, confirmed by cerebral angiography. The patient had left transverse sinus stenting with sustained improvement. This case highlights the importance of considering TVSS in …

BACKGROUND: Pearson syndrome (PS) is a rare multisystem mitochondrial disorder characterized by single large-scale mitochondrial DNA deletions (SLSMDs). It typically presents in infancy with refractory sideroblastic anemia, exocrine pancreatic insufficiency, and failure to thrive. Due to its heterogeneous manifestations and resemblance to other hematological conditions, early diagnosis remains a clinical challenge.

CASE PRESENTATION: A south asian male infant presented with persistent pancytopenia, severe anemia unresponsive to intravenous and oral iron and multivitamin supplements, exocrine pancreatic insufficiency, failure to thrive, and metabolic acidosis. Born to consanguineous parents, the child had a significant family history of early infant deaths and hematological abnormalities. …

When Neighborhoods Change, So Do Schools: Gentrification’S Influence On Public Education, Diego Ramirez

Theses and Dissertations from DePaul University

Neighborhood change is a common feature in urban life; however, gentrification is a distinct form of urban transformation characterized by rising property values, reinvestment, and shifts in neighborhood socioeconomic makeup. This literature review investigates the mechanisms through which gentrification reshapes public education and argues that gentrification has a direct impact on public schools, as these institutions reflect the socioeconomic communities around them. As neighborhoods gentrify and class demographics shift, education systems struggle to meet the demands of changing student populations, leading to unequal educational experiences. Specifically, this literature review demonstrates how gentrification reshapes public education through changes in school enrollment, …

An Exploratory Analysis Of Neurocognitive Performance And Posttraumatic Stress Disorder (Ptsd) Among Latinx Asylum Seekers, Elsie A. Arias

Doctoral Dissertations

Asylum seekers are exposed to violence and traumatic events in their home countries at high rates, leading to mental health challenges such as posttraumatic stress disorder (PTSD). PTSD symptoms and comorbidities such as depression and alcohol misuse are associated with impacts to multiple domains of cognitive functioning among populations such as Veterans. However, the neurocognitive performance of Latinx asylum seekers who experience PTSD symptoms are under-documented in the current literature despite its meaningful impact on clinical care engagement and navigation of the legal process. This study utilized an exploratory, quantitative, cross-sectional design to examine whether higher levels of self-reported PTSD, …

Identity Development For Queer East Asian Americans During The Coming Out Process To Family, Mei E. Tam

Doctoral Dissertations

There has been a growing number of Asian Americans who openly identify as queer, with over half a million residing in the United States (UCLA, 2021). Despite this, psychological research has paid limited attention to how queer and Asian American identities intersect and are integrated, often framing them as conflicting while overlooking culturally embedded meaning-making processes. The present study explored identity formation among cisgender queer East Asian Americans during the critical period of coming out to family, focusing on how their understanding of and relationship to their queer and ethnic identities shifted following disclosure.

Using a qualitative approach, semi-structured interviews …

Nietzsche’S Greek Soul: Traces Of Aristotle’S Psuchē In The Early Nietzsche, Laura G. Campos

Theses and Dissertations from DePaul University

This dissertation proposes an examination of the concept of the soul (Seele) as it appears in the works of Friedrich Nietzsche, in conversation with the concept of the soul in Aristotle. I propose bringing these two historically and theoretically disparate thinkers into dialogue insofar as they each represent a pivotal moment in the history of Western subjectivity, drawing on Martin Heidegger’s positioning of Aristotle and Nietzsche as the inaugural and final thinkers of Western metaphysics, respectively. Yet, following recent Continental interpretations of both thinkers, I read both Aristotle and Nietzsche as proto-phenomenologists concerned with the problem of how to thematize …

Other People's Poverty, Emmanuel Hiram Arnaud, Shaun Ossei-Owusu

Faculty Scholarship

Puerto Ricans have a relationship with the United States that is historically unparalleled. They have been citizens of the United States since 1917, served in every major conflict since World War I, and have been influential members of American culture, politics, and society. Yet, Puerto Rico is not fully part of the United States. The island of 3.2 million people— more than the population of eighteen states—is a U.S. territory. This means the federal government wields its complete and largely unrestrained plenary power over the Island, often treating Puerto Ricans differently than the rest of the United States. This differential …

Prototyping Of A Spectropolarimetry Module For Lenslet-Based Integral Field Spectrographs, Manasa Lakshmi Narasimhan

Theses

Integral-field spectropolarimetry enables simultaneous spatial, spectral, and polarization measurements. Observations of polarized light allow researchers to map magnetic fields, distinguish scattering from intrinsic emission, and characterize the geometry of sources illuminating the large-scale dust distribution within and around galaxies. In tandem with spectral information, polarized emission can be used to detail the kinematics of dust expelled from galaxies and to probe the underlying spectrum of scattered light—measurements that help constrain key open questions such as the missing baryon problem and the role of feedback in galaxy evolution. However, spectropolarimetry is a rare capability among ground-based observatories. This thesis showcases a …

Spikerff: Learning Forward With Layer-Local Plasticity And Semi-Hard Negatives, Karthik Tumkur Kumar

Theses

Effective contrastive learning relies on choosing useful, informative "hard" negative samples. Current hard negative sampling methods designed for traditional artificial neural networks (ANNs) are, in general, computationally costly and are ill-suited to account for the temporal structure relevant to neuromorphic data. To tackle these issues, in this work, we formulate a similarity-guided semi-hard negative sampling strategy for neuromorphic computing based on spiking neural networks (SNNs). We propose SpikeRFF (Spiking Recurrent Forward-Forward), a gradient-free and unsupervised recurrent spiking framework that combines layer-local Forward-Forward learning with semi-hard negative selection and temporally structured negative construction. Positive samples are encouraged to produce high goodness, …

What’S Kept, Caitlin Smith

Theses

This thesis examines the collective psychological aftermath of de-industrialization in a rust belt city, processed through perspectives of nostalgia and betrayal. By reframing childhood memories of instability and inherited narratives, a framework is established for investigating the modalities through which love and attachment may obscure entangled harm, and how grief operates across both collective and personal registers. Found objects are situated as sites of projection where memories are abstracted and reconstituted. The processes of decay and weathering serve as analogues for psychological trauma, reframing deterioration as an inevitable and generative condition. Natural elements act as metaphors for neutrality, challenging imposed …
