Benchmarking And Improving Foundation Model Dietary Estimates From Meal Images, Yongcheng Mu, Jiangwen Sun, Jing He

Computer Science Faculty Publications

Accurate quantifying dietary contents, such as calories, proteins, carbohydrates, and fats, from an image of a meal plate is vital for managing diabetes. Recently, Large Multimodal Models (LMMs) have excelled in complex vision-language tasks due to their use of very large, highly diverse data. This study benchmarked the use of seven LMMs that include full and lightweight models of GPT, Gemini, and Llama for nutrition estimation based on Google's Nutrition5k dataset and our own phone-collected DonateAndLearn dataset. We analyzed the performance of LMMs and the RGB-D fusion model, in which the RGB-D model was specifically trained using Nutrition5k data. On …

Understanding Pii Leakage In Large Language Models: A Systematic Survey, Shuai Cheng, Zhao Li, Shu Meng, Mengxia Ren, Haitao Xu, Shuai Hao, Chuan Yue, Fang Zhang

Computer Science Faculty Publications

Large Language Models (LLMs) have demonstrated exceptional success across a variety of tasks, particularly in natural language processing, leading to their growing integration into numerous facets of daily life. However, this widespread deployment has raised substantial privacy concerns, especially regarding personally identifiable information (PII), which can be directly associated with specific individuals. The leakage of such information presents significant real-world privacy threats. In this paper, we conduct a systematic investigation into existing research on PII leakage in LLMs, encompassing commonly utilized PII datasets, evaluation metrics, and current studies on both PII leakage attacks and defensive strategies. Finally, we identify unresolved …

Computer Science Faculty Publications

This paper presents an efficient implementation of a linear-solver kernel relevant to FUN3D, a suite of computational fluid dynamics software developed at NASA’s Langley Research Center. The linear solver is optimized for a range of block sizes commonly used in FUN3D. The implementation targets Aurora, the Argonne Leadership Computing Facility’s (ALCF) exascale machine featuring Intel Data Center Max 1550 GPUs. The linear solver’s performance is memory bandwidth-bound due to its low arithmetic intensity. The primary performance challenges stem from variable matrix row lengths and indirect memory access patterns inherent in unstructured-grid applications. Variable block sizes introduce additional complexity through differing …

Energy-Based Deep Incomplete Multi-View Clustering, Ziyu Wang, Yiming Du, Rui Ning, Lusi Li

Computer Science Faculty Publications

Incomplete multi-view clustering (IMVC) deals with real-world scenarios where certain views are partially missing, posing significant challenges to effective clustering. Most existing IMVC approaches face a trade-off: imputation-free methods suffer from information bias and imbalance, while full-imputation methods risk introducing and propagating noise. To overcome these limitations, we propose Energy-Based Deep Incomplete Multi-View Clustering (Energy-DIMC), a novel selective-imputation framework that leverages energy-based models (EBMs) to guide reliable imputations and robust clustering. EBMs assess data compatibility by assigning lower energy to more coherent structures, effectively modeling complex inter-view and inter-sample dependencies. Inspired by EBMs, Energy-DIMC integrates four key components: 1) a …

Icu-Length Of Stay Prediction On Electronic Health Records Using Graph Neural Networks And Homogeneous Similarity Graphs, Ahmad F. Al Musawi, Pratip Rana, Sibtanu Raha, Joshua Braunstein, William C. Sleeman Iv, Rishabh Kapoor, Preetam Ghosh

Computer Science Faculty Publications

Predicting the length of stay (LoS) is important for hospital administration, as it helps allocate proper resources, such as bed management and hospital staffing. Patients' Electronic Health Records (EHRs) contain highly relevant data for LoS prediction; however, their integration and effective use in predictive modeling for accurately estimating LoS remain challenging. To address this, we propose a homogeneous Graph Neural Network (GNN)-based framework for predicting LoS. This method employs a comprehensive data fusion strategy based on the hospital Visit-based Similarity Graph (VSG), which integrates diverse multi-modal clinical features into a coherent, homogeneous graph representation. Next, this VSG is fed into …

Humans Vs. Llms On Open Domain Scientific Claim Verification: A Baseline Study, Benjamin Curtis, Stefania Dzhaman, Matthew Maisonave, Jian Wu

Computer Science Faculty Publications

Verifying scientific claims is challenging for the general public because most people lack domain knowledge. Manual verification by subject domain experts is accurate, but it is obviously not scalable to meet the rising number of scientific claims on the Web. Whether the emerging large language models and large reasoning models can be used for scientific claim verification, and how their performances compare to humans, are still research questions. To this end, we developed a new benchmark MSVEC2 that consists of 138 claims from credible fact verification websites and science news outlets. Two tasks were given to both human and LLM …

Privshap: A Finer-Granularity Network Linearization Method For Private Inference, Xiangrui Xu, Zhenzhen Wang, Rui Ning, Chunsheng Xiu, Hongyi Wu

Computer Science Faculty Publications

Private inference applies cryptographic techniques like homomorphic encryption, garble circuit and secret sharing to keep both sides privacy in a client-server setting during inference. It is often hindered by the high communication overheads, especially at non-linear activation layers such as ReLU. Hence ReLU pruning has been widely recognized as an efficient way to accelerate private inference. Existing approaches to ReLU pruning typically rely on coarse hypothesis, which assume an inverse correlation between the importance of ReLU and linear layers or shallow activation layers have less importance for universal models, to assign the budgets according to the layer while preserving the …

Nexus: Network Exploration For Exploiting Unsafe Sequences In Multi-Turn Llm Jailbreaks, Javad Rafiei Asl, Sidhant Narula, Mohammad Ghasemigol, Eduardo Blanco, Daniel Takabi

Computer Science Faculty Publications

Large Language Models (LLMs) have revolutionized natural language processing, yet remain vulnerable to jailbreak attacks—particularly multi-turn jailbreaks that distribute malicious intent across benign exchanges, thereby bypassing alignment mechanisms. Existing approaches often suffer from limited exploration of the adversarial space, rely on hand-crafted heuristics, or lack systematic query refinement. We propose NEXUS (Network Exploration for eXploiting Unsafe Sequences), a modular framework for constructing, refining, and executing optimized multi-turn attacks. NEXUS comprises: (1) ThoughtNet, which hierarchically expands a harmful intent into a structured semantic network of topics, entities, and query chains; (2) a feedback-driven Simulator that iteratively refines and prunes these chains …

Contextual Memory Recall: A Novel Metric For Class Incremental Learning, Balasubramanian S, Sai Subramaniam M., Sai Sriram Talasu, Yedu Krishna P., Pranav Phanindra Sai M., Darshan Gera, Ravi Mukkamala

Computer Science Faculty Publications

We propose a novel metric for class incremental learning (CIL) called Contextual Memory Recall (CMR), which evaluates how well a CIL model recalls previously learned classes when given relevant past cues. Inspired by human memory, CMR offers newer insights into continual aspects of a CIL model that were not addressed by previously proposed metrics for CIL. Specifically, the standard metric, average incremental accuracy (AIA), overlooks the quality of evolving feature representations, whereas our proposed CMR accounts for it. As a result, methods using feature distillation perform well under AIA but poorly under CMR, while those without feature distillation excel under …

Major Adverse Cardiovascular Events Are Less Frequent In Psoriasis Patients Starting Glp-1ra Compared To Controls: An Observable Retrospective Cohort Study, Ana Ormaza Vera, Marla F. Osorlo, Madison Olexson, June Choi, Chunghwan Ro, Clinton Enos

Department Dermatology Faculty Publications

Background: Psoriasis is an independent risk factor for major adverse cardiovascular events (MACE). We have previously shown that psoriasis patients with dyslipidemia have an increased incidence of MACE despite treatment with a biologic and a statin. Glucagon-like peptide-1 receptor agonists (GLP-1RA) have shown to reduce MACE in patients with type 2 diabetes and obesity, comorbidities that commonly co-occur with psoriasis. However, the association between GLP-1RA and the incidence of MACE among patients with psoriasis remains unknown.

Methods: We conducted a retrospective cohort study from 2014-2024 using a large, multi-center, electronic health record network (TriNetX). Patients aged 18-90 who started GLP-1RA …

Tryptophan Kynurenine Pathway-Based Imaging Agents For Brain Disorders And Oncology-From Bench To Bedside, Erik Stauff, Wenqi Xu, Heidi H. Kecskemethy, Sigrid A. Langhans, Vinay V. R. Kandula, Lauren W. Averill, Xuyi Yue

Jefferson Hospital Staff Papers and Presentations

Tryptophan (Trp)-based radiotracers have excellent potential for imaging many different types of brain pathology because of their involvement with both the serotonergic and kynurenine (KYN) pathways. However, radiotracers specific to the kynurenine metabolism pathway are limited. In addition, historically Trp-based radiopharmaceuticals were synthesized with the short-lived isotope carbon-11. A newer generation of Trp-based imaging agents using the longer half-lived and commercially available isotopes, such as fluorine-18 and iodine-124, are being developed. The newly developed amino acid-based tracers have been demonstrated to have favorable radiochemical and imaging characteristics in pre-clinical studies. However, many barriers still exist in the clinical translation of …

Emcreg-International Multidisciplinary Consensus Panel On Management Of Hyperkalemia In Chronic Kidney Disease And Heart Failure, Natalie Kreitzer, Nancy M. Albert, Alpesh N. Amin, Craig J. Beavers, Richard C. Becker, Gregg Fonarow, W. Brian Gibler, Katherine W. Kwon, Robert J. Mentz, Biff F. Palmer, Charles V. Pollack, Iliana L. Piña

Division of Cardiology Faculty Papers

BACKGROUND: Hyperkalemia, generally defined as serum potassium levels greater than 5.0 mEq/L, poses significant clinical risks, including cardiac toxicity and muscle weakness. Its prevalence and severity increase in patients with chronic kidney disease (CKD), diabetes mellitus, and heart failure (HF), particularly when compounded by medications like angiotensin converting inhibitors, angiotensin receptor blockers, and potassium sparing diuretics. Hyperkalemia arises from disruptions in potassium regulation involving intake, excretion, and intracellular-extracellular distribution. In CKD and acute kidney injury, these regulatory mechanisms are impaired, leading to heightened risk. The management of chronic hyperkalemia presents a challenge due to the necessity of balancing effective cardiovascular …

Bloody Sunday, Bloody Ireland, Bloody Textiles, Catherine Harper Phd

Arts and Design

The fabric of the island of Ireland is marked by the leakage of persistent sores and unhealed wounds borne by the unhealed messy flesh of the national body, which is symbolically swaddled, shrouded, stifled and sheltered by cloth. Ireland is a stained and bloodied cloth, marked irreversibly by conflict and abuse, bloodied by repression and denial, sullied by hunger and history. Blood, flowing from stigmata onto cloth, haemorrhage in extremis from wounds, real or imagined, is steeped deep into the Irish psyche, reflecting a narrative of abjection, sacrifice, memory and mourning.

An Empirical Assessment Of New Jersey's Mistaken Imprisonment Act, Jeffrey Gutman

GW Law Faculty Publications & Other Works

In their article “Compensation for the Convicted Innocent in New Jersey: Problems and Recommended Solutions,” Professors D. Michael Risinger and Lesley Risinger masterfully recount the history and flaws of New Jersey’s Mistaken Imprisonment Act.1 The professors recommend concrete and common-sense amendments to the Act that, if enacted, would resolve statutory ambiguities, remedy bad public policy, and make more generous an Act intended to benefit the wrongfully convicted, but which often falls short of that goal.

This article will provide empirical and comparative context for the Risingers’ proposals. By examining why the claims of exonerees had been denied or never made, …

Agency Delay And The Courts, Aram A. Gavoor, Steven A. Platt

GW Law Faculty Publications & Other Works

Administrative delay plagues the modern regulatory state, yet scholars and courts lack a coherent framework for analyzing when delay becomes unlawful and how to remedy it. This Article provides the first comprehensive examination of judicial oversight of agency delay, tracing the evolution from common law mandamus through the delay provisions of the Administrative Procedure Act. It reveals critical distinctions between these mechanisms that courts have increasingly elided, leading to doctrinal confusion and ineffective remedies. On account of the second Trump administration’s Department of Government Efficiency initiatives, this topic takes on unprecedented urgency because administration policies to reduce workforce and restructure …

Justice Delayed By Design: The Harms Of Our Protracted Divorce System, Laurie S. Kohn

GW Law Faculty Publications & Other Works

Divorce is the termination of a legal relationship. It is necessary for the enforceable division of property and debts between spouses as well as for remarriage. However, it’s not simply a lawsuit. Instead, it most often involves a seismic shift in the very foundations of life and, as such, frequently provokes, exacerbates, and exposes insecurities, instabilities, and vulnerabilities. This legal process also involves a unique relationship between litigants who are former intimate partners—often co-parents—and who are largely unrepresented and therefore engaged in a new form of relationship as opposing parties to a lawsuit. Given these complex dynamics, one might hope …

Circuit Capture And The National Court Of Appeals, John P. Collins Jr.

GW Law Faculty Publications & Other Works

We are facing a crisis of confidence in our federal courts. Polarization in the judicial selection process and partisanship in judicial decision-making have yielded a steep decline in the public’s trust of the judicial branch. Much of the blame lies with the Supreme Court, whose repeated ethical scandals and aggressive rightward tilt have renewed calls for major court reform—from court packing to jurisdiction stripping, from term limits to lottery dockets, and much more in between. But the Supreme Court is not the only court in need of reform. The vast majority of cases go no further than the thirteen U.S. …

The Looming Threat Of Uninsured Nonbank Stablecoins, Arthur E. Wilmarth Jr.

GW Law Faculty Publications & Other Works

On May 21, 2025, the U.S. Senate voted to begin final consideration of the “GENIUS Act.” Despite its lofty title, the bill would create grave threats to our financial system and economy by allowing nonbanks to issue stablecoins without the protections provided by federal deposit insurance and other regulatory safeguards governing FDIC-insured banks. The GENIUS Act would set the stage for future runs on stablecoins triggering systemic financial crises and requiring government bailouts.

The great majority of global stablecoins promise to maintain parity with the U.S. dollar and are functionally equivalent to bank deposits. Stablecoins are mainly used as payment …

The Future Of The Duty To Engage In Reasoned Decision Making: The Choice Between A Textual Approach And A Pragmatic Approach, Richard J. Pierce Jr

GW Law Faculty Publications & Other Works

In this contribution to a symposium on the future of the duty to engage in reasoned decision making, Professor Pierce argues that the Supreme Court faces a decision whether to retain the present robust version of the duty to engage in reasoned decision making and to extend it to actions taken by the president or to abandon or greatly weaken it. He urges the Court to retain and expand the scope of the duty to include actions taken by the president. He expresses concern, however, that the Court may instead abandon or significantly weaken the duty.

The Supply Chain Is A Circle: Ai, Privacy, And People, Alicia Solow-Niederman

GW Law Faculty Publications & Other Works

Artificial Intelligence (AI) governance underscores the AI “supply chain” and the “many hands” involved in the creation of AI systems. Although invaluable, this production-centered approach risks overlooking what happens when people use AI tools. That’s a mistake, because user interactions determine the real-world impact of AI.

This Essay contends that regulating AI and holding the appropriate actors responsible requires far more attention to what happens after deployment of an AI system. The supply chain is an invaluable start, but it’s not a linear chain. Rather, it is a circle that must incorporate users’ engagement with AI tools as part of …

The Supreme Court Should Overrule Red Lion, Richard J. Pierce Jr

GW Law Faculty Publications & Other Works

In this essay Professor Pierce uses the Jimmy Kimbell incident as the point of entry for his argument that the Supreme Court’s 1969 opinion in Red Lion v. FCC is inconsistent with today’s reality and dangerous. He urges the Court to overrule it.

The Civil Jury Trial Clause Of The Seventh Amendment, Renée Lettow Lerner

GW Law Faculty Publications & Other Works

This essay discusses the Civil Jury Trial Clause—also known as the Preservation Clause—of the Seventh Amendment to the U.S. Constitution. I provide background on English civil jury practice in common-law courts in the late eighteenth century and distinguish it from equity practice in the Court of Chancery. The essay describes Blackstone’s praise for the civil jury as well as the role the civil jury played in the events leading up to the American Revolution. The question of a federal constitutional right to civil jury trial provoked heated disputes in the Philadelphia Convention and the ratification debates. The ratification debates featured …

The Re-Examination Clause Of The Seventh Amendment, Renée Lettow Lerner

GW Law Faculty Publications & Other Works

This essay discusses the origins, history, and current interpretation of the Re-examination Clause of the Seventh Amendment to the U.S. Constitution. As Justice Joseph Story declared, the Re-examination Clause is separate from the right to civil jury trial in the Amendment’s Preservation Clause. The Re-examination Clause states that no fact tried by a jury shall be “re-examined” in federal court except by the rules of “the common law.” This provision had no counterpart in the state constitutions. The essay explains the methods of review of jury verdicts in English common-law courts in the late eighteenth century, focusing on the remedy …
