Meta-Clustering For Specialized Language Models: Enhancing Contextual Adaptation And Mitigating Hallucinations In Diverse Healthcare Environments, Joshit Mohanty, Vaishali Vaishali, Sandeep Kumar Nayak, Sumit Lahiri

Graduate Student Government Association Research Conference

Large Language Models (LLMs) have significantly advanced conversational AI by enabling dialogic information-seeking and task execution across diverse domains. However, their extensive parameters and broad domain scope lead to “data hallucinations.” These shortcomings are particularly evident in dynamic and diverse environments like India’s healthcare sector, where myriad languages, regional practices, and cultural nuances demand specialized, localized expertise rather than one-size-fits-all generalist models. This paper introduces a meta-clustering framework that integrates Distilled Language Models (DLMs) and Small/Specialized Language Models (SLMs) with meta-learning principles to address these limitations. By drawing on evidence from works such as MedHalu and Med-HALT, the framework seeks …

Tamos: Task-Aware Multi-Agent Orchestrator System, Joshit Mohanty, Sandeep Kumar Nayak, Sumit Lahiri

Graduate Student Government Association Research Conference

Large language models (LLMs) are increasingly at the core of multi-agent systems (MAS). However, the high resource demand, error propagation, and lack of adaptive evaluation mechanisms pose significant challenges in deploying these agentic solutions at scale. To address these concerns, this research proposes a Task-Aware Multi-Agent Orchestrator System designed to refine the agentic framework, categorizing tasks autonomously, assigning specialized evaluation datasets, and balancing token usage against functional effectiveness. This approach underscores robust data management, including AsyncHow, Mosaic AI, and Synthetic Preference Optimization (PO) corpora. Each dataset targets specific dimensions of agent performance, such as dynamic task decomposition and tool integration …

Graphtreemed: A Hybrid Graph-Tree Rag Architecture For Mission-Critical Medical Applications, Joshit Mohanty, Sandeep Kumar Nayak, Sumit Lahiri

Graduate Student Government Association Research Conference

Studies within engineering management indicate that decision-making is often based on the cognitive processing of grouped and pictographic information clusters entangled with high-level pattern recognition. Similarly, graph-based retrieval-augmented generation (RAG) architectures substantially improve diagnostic accuracy and interpretability, while tree-structured systems reduce critical misses through hierarchical reasoning. However, existing solutions often lack a unified framework that seamlessly integrates these two paradigms to address the multifaceted demands of mission-critical healthcare settings. This proposal introduces GraphTreeMed, a novel hybrid RAG architecture designed to harness the complementary strengths of graph-based and tree-based retrieval mechanisms, thereby advancing the safety and efficacy of clinical decision support …

Field-Theoretic Context System (Ftcs), Subhadip Mitra

Defensive Publications Series

This disclosure describes an approach to context processing that models context as interacting fields rather than discrete states. A field-theoretic context system (FTCS) as described herein enables natural context flow, relationship preservation, and dynamic evolution through partial differential equations that govern field dynamics. The FTCS described herein represents an advancement in context processing by replacing discrete states with continuous, evolving fields. This approach more accurately reflects how information behaves in real-world systems. A key aspect is the non-conservative approach of the FTCS by which context can be genuinely created, amplified, diminished, or eliminated as information gains or loses relevance. This …

Building Climate Resilience Through Food Recovery, San Diego Regional Climate Collaborative, Alexander Pourfard, Aranza Ruvalcaba

San Diego Regional Climate Collaborative

In an effort to combat GHG emissions from food waste, California passed Senate Bill 1383 (SB 1383) into law in 2016. The bill contains key provisions aimed at increasing edible food recovery. By rescuing food that would otherwise go to the landfill, California entities have been able to help save precious food and advance sustainable solutions to address climate change in their local communities. Since the food recovery requirements took effect in January of 2022, over 217,000 tons of unsold food have been recovered annually, providing more than 700 million meals to food-insecure Californians.

Physics Faculty Research & Creative Works

The structural, electronic, and optical properties of amorphous SnO and Sn-Ta-O (with Sn:Ta ratios 5:1, 3:2, and 1:2) are investigated as a function of density and metal composition using ab initio molecular dynamics simulations and hybrid functional calculations. The short- and medium-range structures of amorphous oxides are thoroughly studied by calculating the effective coordination numbers, effective distances, distortion, and their time variances for metal-oxygen (M-O), O-M, M-M shells, the M-O-M and O-M-O angle distribution, as well as the volume, shape, and distribution of structural voids. Disorder is found to suppress both Sn-O and Sn-Sn coordination but not the O-Sn coordination. …

Using The Narrative Roles Questionnaire Within An Academic Setting, Toby Stipp

Student Theses and Dissertations

Criminal profiling has become a useful tool for many agencies when investigating a variety of crimes. The proposed study used a questionnaire originally designed for criminal behavior and profiling, the Narrative Roles Questionnaire (NRQ), and observed if it could be translated to an academic setting pertaining to academic cheating. A pilot study involving definitions of the four narratives in the NRQ revealed that both the Professional and Victim narratives are more likely to be the narratives that academic cheaters would acknowledge. In the proposed study, participants were asked to write down a cheating scenario and fill out the full NRQ …

A Novel Approach To Detect Shapes Of Constant Width, Ian D. Monk

Bodies of constant width have been studied mathematically since Euler and have found various applications in engineering and other areas. In this paper, we seek to develop novel tools to gain deeper insights into these shapes and to better be able to analyze them. The idea which motivates the development in this paper is as follows: a body has constant width if and only if the chord connecting the intersections of the boundary of the body with each pair of parallel hyper planes which lie tangent to a body lies perpendicular to the hyper planes.This is a known fact and …

Modeling Differential Expression In Scrna-Seq Data With A Difference Of Two Negative Binomial Distributions, Alicia Petrany

Theses and Dissertations

Single cell RNA sequencing (scRNA-seq) is a powerful high throughput sequencing technology that quantifies the transcriptome at a single cell resolution. Differential expression (DE) analysis is a key scRNA-seq analysis task that identifies genes with statistically significant expression changes in response to biological stimuli. Existing DE methods inherently attempt to determine whether two sets of negative binomially distributed read counts are significantly different but lack exact testing strategies to do so. This work introduces a novel theoretical distribution, the Difference of Two Negative Binomial Distributions (DOTNB), and implements it within DEGage, an R package for DE analysis. Benchmarking DEGage against …

Student Theses and Dissertations

This study aimed to examine the efficacy of literacy intervention in first and second-grade at-risk readers at an after-school program, CityYouth Ministries, in Jonesboro, AR. It was hypothesized that if children at risk for literacy difficulties receive literacy intervention at an after-school program, they would have better reading outcomes, narrowing the gap in academic achievement. If successful, it may resolve the need for long-term literacy support at school, which has been frequently observed with this population. The study utilized a quasi-experimental, within-group pretest-posttest design. Reading fluency and sight word knowledge were measured using DIBELS-8 Oral Reading Fluency passages and Dolch …

The Locus Of Intersecting Tangents, James Austin Canard

Student Theses and Dissertations

Consider two tangent lines to a given function, whose horizontal distance between the tangent points is a constant h. As the tangent lines change on the function, the intersection of the two tangent lines trace out a curve. We study the relationship between this new curve, called the locus curve, and the original function. We begin by studying the effects of vertical scaling, vertical shifting, vertical sheering, horizontal scaling, and horizontal shifting. Then we use asymptotical methods to study the behavior of the locus as the tangent lines approach infinity. We use a similar method to observe the behavior as …

Emergence Of Heterogeneity In Bacteria During Antibiotic Exposures, Mirjana Stevanovic

Dartmouth College Ph.D Dissertations

Bacterial populations exposed to antibiotics often exhibit phenotypic heterogeneity, with individual cells displaying distinct responses with fates ranging from survival to arrest or death. The emergence of this heterogeneity is largely driven by feedback mechanisms mediated by the interactions between antibiotic action, gene regulation, and cellular metabolism. These responses unfold in dynamic environments where conditions such as nutrient availability and drug concentration fluctuate over time and space. Yet, these complex interactions and their role in shaping population-level outcomes during drug responses remain poorly understood. Using tetracycline resistance in E. coli as a model system, this thesis focuses on how these …
