Dropouts in Confidence: Moral Uncertainty in Human-LLM Alignment

AAAI 2026technical

Humans display significant uncertainty when confronted with moral dilemmas, yet the extent of such uncertainty in machines and AI agents remains underexplored. Recent studies have confirmed the overly confident tendencies of machine-generated responses, particularly in large language models (LLMs).

Mitigating Plasticity Loss through Architectural Design in Continual Learning

ICML 2026poster

Neural networks for continual reinforcement learning (CRL) often suffer from plasticity loss, i.e., a progressive decline in their ability to learn new tasks arising from increased representational drift (churn) and Neural Tangent Kernel (NTK) rank collapse. Current methods mitigating this problem i…

Textual Supervision Enhances Geospatial Representations in Vision-Language Models

ICML 2026poster

Geospatial understanding is a critical yet underexplored dimension in the development of machine learning systems for tasks such as image geolocation and spatial reasoning. In this work, we analyze the geospatial representations acquired by three model families: vision-only architectures (e.g., ViT)…
