Enhancing Llm-Based Coding Tools Through Native Integration Of Ide-Derived Static Context, Yichen Li, Yun Peng, Yintong Huo, R. Michael Lyu

Research Collection School Of Computing and Information Systems

Large Language Models (LLMs) have achieved remarkable success in code completion, as evidenced by their essential roles in developing code assistant services such as Copilot. Being trained on in-file contexts, current LLMs are quite effective in completing code for single source files. However, it is challenging for them to conduct repository-level code completion for large software projects that require cross-file information. Existing research on LLM-based repository-level code completion identifies and integrates cross-file contexts, but it suffers from low accuracy and limited context length of LLMs. In this paper, we argue that Integrated Development Environments (IDEs) can provide direct, accurate and …

Semantic Loss-Guided Data-Efficient Supervised Fine-Tuning For Safe Responses In Llms, Yuxiao Lu, Pradeep Varakantham, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

Large Language Models (LLMs) generating unsafe responses to toxic prompts is a significant issue in their applications. While various efforts aim to address this safety concern, previous approaches often demand substantial human data collection or rely on the less dependable option of using another LLM to generate corrective data. In this paper, we aim to take this problem and overcome limitations of requiring significant high-quality human data. Our method requires only a small set of unsafe responses to toxic prompts, easily obtained from the unsafe LLM itself. By employing a semantic cost combined with a negative Earth Mover Distance (EMD) …

Harnessing A Paradox Mindset To Straddle Two Worlds: The Relationship Between Paradox Mindset And Professional, Social, And Well-Being Outcomes Via Identity Integration Among Low-Ses College Students, Xiaoyu Dai

Dissertations and Theses Collection (Open Access)

Low-SES college students often face contradictory demands and expectations as they navigate between their home and college environments. Grounded in prior evidence demonstrating the benefits of a paradox mindset—characterized by “both/and” thinking and a tendency to accept, value, and feel comfortable with tensions—in situations that involve contradictions, this research hypothesized that a paradox mindset promotes professional, relational, and well-being outcomes among low-SES college students. Importantly, SES-college identity integration, defined as perceived blendedness and harmony between one’s socioeconomic class identity and college student identity, was proposed as a key mediating mechanism underlying these benefits. Three studies were conducted with low-SES undergraduate …

The Charm Of Chaos: How Disordered Displays Of Cute Objects Enhance Perceived Cuteness And Boost Purchase Intention, Ting He

Dissertations and Theses Collection (Open Access)

This study investigated how the order of display influences consumer perceptions of cuteness and their purchase intention in the growing "Cute Economy" era. Contrary to conventional visual merchandising principles, we propose that disordered displays enhance the perceived cuteness of products compared to ordered displays. Through three experimental studies, we confirmed that objects in disordered displays are perceived significantly cuter than objects in ordered ones. We further identified that perceived realness as the underlying psychological mechanism plays a mediating effect; disordered display creates an impression of realness and life-like characteristics that amplify perceptions of cuteness. In addition, our field study findings …

A novel scheme is proposed for the distributed multi-ship collision avoidance (CA) problem with consideration of the autonomous, dynamic nature of the real circumstance. All the ships in the envisioned scenarios can share their decisions or intentions through route exchange, allowing them to make subsequent decisions based on the route planning in each iteration. By leveraging route exchange, the multi-ship CA problem involves iterations for negotiation, and is regarded as a staged cooperative game under conditions of complete information. The concept of closest spatio-temporal distance (CSTD) is introduced to more accurately assess collision risk between ships. A coordinated CA mechanism …

Samgpt: Text-Free Graph Foundation Model For Multi-Domain Pre-Training And Cross-Domain Adaptation, Xingtong Yu, Zechuan Gong, Chang Zhou, Yuan Fang, Hui Zhang

Research Collection School Of Computing and Information Systems

Graphs are able to model interconnected entities in many online services, supporting a wide range of applications on the Web. This raises an important question: How can we train a graph foundational model on multiple source domains and adapt to an unseen target domain? A major obstacle is that graphs from different domains often exhibit divergent characteristics. Some studies leverage large language models to align multiple domains based on textual descriptions associated with the graphs, limiting their applicability to text-attributed graphs. For text-free graphs, a few recent works attempt to align different feature distributions across domains, while generally neglecting structural …
