Conformal Constrained Policy Optimization for Cost-Effective LLM Agents
Wenwen Si, Sooyong Jang, Insup Lee +1
While large language models (LLMs) have recently made tremendous progress towards solving challenging AI problems, they have done so at increasingly steep computational and API cos…
Pattern-Guided Diffusion Models
Vivian Lin, Kuk Jin Jang, Wenwen Si +1
Diffusion models have shown promise in forecasting future data from multivariate time series. However, few existing methods account for recurring structures, or patterns, that appe…
Quantifying and Improving Adaptivity in Conformal Prediction through Input Transformations
Sooyong Jang, Insup Lee
Conformal prediction constructs a set of labels instead of a single point prediction, while providing a probabilistic coverage guarantee. Beyond the coverage guarantee, adaptivenes…
Assessing Modality Bias in Video Question Answering Benchmarks with Multimodal Large Language Models
Jean Park, Kuk Jin Jang, Basam Alasaly +5
Multimodal large language models (MLLMs) can simultaneously process visual, textual, and auditory data, capturing insights that complement human analysis. However, existing video q…
Fundus Image-based Visual Acuity Assessment with PAC-Guarantees
Sooyong Jang, Kuk Jin Jang, Hyonyoung Choi +4
Timely detection and treatment are essential for maintaining eye health. Visual acuity (VA), which measures the clarity of vision at a distance, is a crucial metric for managing ey…
