About

Dr. Yuanyuan Lei is an Assistant Professor of Computer Science at the University of Florida. Her research focuses on Natural Language Processing (NLP), Large Language Models (LLMs), Machine Learning, and Artificial Intelligence. Her research vision is to develop innovative algorithms and systems for knowledge-aware language modeling, enriching LLMs with diverse forms of knowledge to advance reasoning and planning capabilities, as well as to ensure trustworthiness and safety alignment of LLMs. She is interested in integrating NLP models and LLMs into various domains such as science, engineering, healthcare, and law. Her work has been published in top venues including ACL, EMNLP, and NAACL. She has received recognition as a Rising Star in Data Science from the University of Chicago and as a Future Research Leader in Artificial Intelligence from the University of Michigan.

• NFL fandom and unhealthy eating behavior: Exploring the role of introspective focus from a functionalist perspective of emotions

  Sport Management Review · 2023 · 6 citations

  We examine the effects of team identification on unhealthy eating behavior. Leveraging the functionalist perspective of emotions, we also examine how an introspective focus on particular affective states impacts this phenomenon. The results of two online studies (one cross-sectional survey, one experiment) indicate fans display emotional eating, implicit preferences toward high-calorie, indulgent foods, and higher body mass index (BMI) numbers when they identify highly with a sport team. Further…

• Adolescent Health and Dark Personalities: The Role of Socioeconomic Status, Sports, and Cyber Experiences

  International Journal of Environmental Research and Public Health · 2024 · 1 citations

  By investigating the impact of dark personality traits on adolescent health, this study explores the interplay among economic disadvantage, spectator sports involvement, and cyber victimization. We analyzed data from 1844 students aged 13-17 in a school district in the USA, and our findings reveal positive associations between economic disadvantage and both Machiavellianism and psychopathy, influencing negative emotions-driven eating. Spectator sports engagement exhibits links with Machiavellian…

• Statistical analysis of twin kHz QPO in LMXBs

  arXiv (Cornell University) · 2013-01-23 · 1 citations

  preprintOpen access

  With 26 twin kilohertz quasi-periodic oscillation (kHz QPO) sources in neutron star (NS) low-mass X-ray binaries (LMXBs) published before 2012, we analyze the centroid frequency ({\nu}) distribution of twin kHz QPOs (lower frequency {\nu}1 and upper frequency {\nu}2) both for Atoll and Z sources. For the data without shift-and- add, we find that Atoll and Z sources show the different distributions of {\nu}1, {\nu}2 and {\nu}2/{\nu}1, but the same distribution of \Delta{\nu} (difference of twin k…

• kHz QPOs and Spin Frequencies The correlations between the spin frequencies and kHz QPOs of Neutron Stars in LMXBs

  arXiv (Cornell University) · 2007-05-10

  articleOpen access

  We studied the correlations between spin frequencies and kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low mass X-ray binaries. The updated data of kHz QPOs and spin frequencies are statistically analyzed. We found that when two simultaneous kHz QPOs are present in the power spectrum, the minimum frequency of upper kHz QPO is at least 1.3 times larger than the spin frequency, i.e. \nu_{s}<\nu_{2min}/1.3. We also found that the average kHz QPO peak separation in 6 Atoll sources…
