Exploiting Local Flatness for Efficient Out-of-Distribution Detection

Seonghwan Park, Hyunji Jung, Dongyeop Lee +1

Detecting out-of-distribution (OOD) data is crucial for reliable machine learning deployment. Among detection strategies, post-hoc methods are particularly attractive due to their…

Quantifying Aleatoric Uncertainty of In-Context Learning for Robust Measure of LLM Prediction Confidence

Jinseok Chung, Minkyoung Song, Hyunji Jung +1

In-Context Learning (ICL) allows LLMs to adapt to new tasks from a few demonstrations, but its reliability remains a concern: predictions are highly sensitive to both prompt design…

The Unseen Frontier: Pushing the Limits of LLM Sparsity with Surrogate-Free ADMM

Kwanhee Lee, Hyeondo Jang, Dongyeop Lee +2

Neural network pruning is a promising technique to mitigate the excessive computational and memory requirements of large language models (LLMs). Despite its promise, however, progr…

An Analysis of Concept Bottleneck Models: Measuring, Understanding, and Mitigating the Impact of Noisy Annotations

Seonghwan Park, Jueun Mun, Donghyun Oh +1

Concept bottleneck models (CBMs) ensure interpretability by decomposing predictions into human interpretable concepts. Yet the annotations used for training CBMs that enable this t…

SASSHA: Sharpness-aware Adaptive Second-order Optimization with Stable Hessian Approximation

Dahun Shin, Dongyeop Lee, Jinseok Chung +1

Approximate second-order optimization methods often exhibit poorer generalization compared to first-order approaches. In this work, we look into this issue through the lens of the…
