Journal of Physics Communications2024This study investigates the application of machine learning (ML) models for predicting transient responses in ball-impact elastodynamics simulations. We focus on the canonical problem of ball impact on laminated structures, which captures essential physics while maintaining computational tractability. Novel contributions include: (1) development of a temporal multi-resolution strategy for stable long-time

Machine Learning for Health Symposium 20242024Generalist large language models (LLMs), not developed to do particular medical tasks, have achieved widespread use by the public. To avoid medical uses of these LLMs that have not been adequately tested and thus minimize any potential health risks, it is paramount that these models use adequate guardrails and safety measures. In this work, we propose a synthetic medical prompt generation method to evaluate

ECIR 20252024Training sequential recommenders such as SASRec with uniform sample weights achieves good overall performance but can fall short on specific user groups. One such example is popularity bias, where mainstream users receive better recommendations than niche content viewers. To improve recommendation quality across diverse user groups, we explore three Distributionally Robust Optimization(DRO) methods: Group

ASEE 20242024Many students choose to major in engineering to join the community of professional engineers and gain exposure to the field through their college experience [1]. However, research suggests that engineering graduates may not be adequately prepared for the workplace due to the complexities of engineering work [2]. Engineering work involves complexity, ambiguity, and contradictions [3], and developing innovation

ICLR 2024 Workshop on AI4DifferentialEquations in Science2024Incomplete tabular datasets are ubiquitous in many applications for a number of reasons such as human error in data collection or privacy considerations. One would expect a natural solution for this is to utilize powerful generative models such as diffusion models, which have demonstrated great potential across image and continuous domains. However, vanilla diffusion models often exhibit sensitivity to
