Documentation-Aware Code Generation Via Retrieval Augmented Generation, Daniel Amirtharaj, Rahmin Norwood

Computer Science and Engineering Senior Theses

Modern large language models (LLMs) increase the speed of software development but frequently hallucinate code, forcing developers to debug and rewrite generated code manually. This project introduces Documentation-Aware Code Generation, a retrieval-augmented generation (RAG) framework that injects authoritative documentation into the LLM prompt to reduce hallucinations in generated code. We build an ingestion pipeline that scrapes, cleans, chunks, and embeds official API documentation into a Pinecone vector database, then design a retrieval and re-ranking pipeline that retrieves the most relevant snippets for each user query. Results show that augmenting prompts with documentation lowers code hallucination by up to 60%. The …

Neural Ranking In Sparse Data Environments, Xuyang Wu

Engineering Ph.D. Theses

Neural ranking models have become central to modern information retrieval (IR) systems, powering applications such as web search, product recommendation, and question answering. However, their effectiveness often hinges on access to abundant labeled supervision, a condition that is rarely met in real-world scenarios. In many domains, including e-commerce, healthcare, and legal search, labeled user interactions (e.g., clicks, purchases, or expert annotations) are sparse, especially for long-tail queries and new content. This data sparsity challenges the generalization, adaptability, and fairness of traditional ranking approaches.

This thesis presents a unified investigation of neural ranking under sparse supervision, introducing novel methods and analytical …

From Vigilance To Veracity: Hallucination Detection, Mitigation, And Safety Enhancement In Large Language Models, Sharanya Dasgupta

Master’s Dissertations

Human cognition, driven by complex neurochemical processes, oscillates between imagination and reality and learns to self-correct whenever such subtle drifts lead to hallucinations or unsafe associations. In recent years, large language models (LLMs) have garnered widespread attention due to their adeptness at generating innovative responses to the given prompts across a multitude of domains, yet they exhibit a critical limitation: the propensity to produce factually incorrect and potentially harmful content while preserving syntactic coherence and logical structure. In this work, we hypothesize that these deficiencies in LLMs originate from their internal representational dynamics. Our observations indicate that, during passage generation, …
