Transforming Chatbot Text: A Sequence-To-Sequence Approach To Human-Like Text Generation, Natesh Reddy Jan 2025

Transforming Chatbot Text: A Sequence-To-Sequence Approach To Human-Like Text Generation, Natesh Reddy

Master's Projects

With the advancements in Large Language Models (LLMs) such as ChatGPT, the boundary between text written by a human and that created by AI has become blurred. This poses a threat to systems designed to detect AI-generated content. In this work, we adopt a novel strategy to adversarially transform GPT-generated text using sequence-to-sequence (Seq2Seq) models, to make the text more human-like. We concentrate on improving GPT-generated sentences by including significant linguistic, structural, and semantic components that are typical of human-authored text. The goal is to then use this transformed data to train a more robust detection model. Our experiments show …

An Evidence-Based Approach To Predicting Pancreatic Ductal Adenocarcinoma, Surya Teja Nalluri Jan 2025

An Evidence-Based Approach To Predicting Pancreatic Ductal Adenocarcinoma, Surya Teja Nalluri

Master's Projects

Pancreatic ductal adenocarcinoma (PDAC) is a complex disease with hidden clinical indicators, so a reliable diagnosis of PDAC requires high precision and sophisticated analysis. Traditional probabilistic methods often rely on making unwarranted assumptions or undesirable approximations about probabilistic estimates, limiting their ability to provide the precision needed for correct diagnosis and treatment planning. In contrast, Dempster–Shafer Theory offers a formal framework for integrating uncertain and potentially conflicting evidence. This makes it well-suited for analyzing incomplete and ambiguous data typically associated with PDAC. By employing an evidential reasoning (ER) model based on Dempster-Shafer Theory, this approach systematically combines and evaluates imperfect …

Moral Intensity Dimensions Of Information Security Policy Compliance: Perspectives Of Construal Level Theory And Ethical Theories, Dailin Zheng, Zhiping Walter

Faculty Research, Scholarly, and Creative Activity

Sanctions are often ineffective in promoting employee compliance with information systems security policies (ISSPs) and may lead to undesired outcomes. We establish that ISSP compliance is an ethical decision and examine it through the lens of ethical decision-making using scenario-based surveys. Guided by normative ethical theories and the construal level theory, we find that both the opinions of co-workers and perceived negative consequences of noncompliance to the organization influence employee ISSP compliance intention. Additionally, perceived social distance affects employees' assessment of when damages to the organization can occur. Both the assessed timing of damage and the perceived social distance from …
