Pragma-VL: Towards a Pragmatic Arbitration of Safety and Helpfulness in MLLMs

ICLR 2026poster

Multimodal Large Language Models (MLLMs) pose critical safety challenges, as they are susceptible not only to adversarial attacks such as jailbreaking but also to inadvertently generating harmful content for benign users. While internal safety alignment via Supervised Fine-Tuning (SFT) and Reinforce…

Differentially Private Federated Low Rank Adaptation Beyond Fixed-Matrix

NeurIPS 2025poster

Large language models (LLMs) typically require fine-tuning for domain-specific tasks, and LoRA offers a computationally efficient approach by training low-rank adaptors. LoRA is also communication-efficient for federated LLMs when multiple users collaboratively fine-tune a global LLM model without s…

FAPEX: Fractional Amplitude-Phase Expressor for Robust Cross-Subject Seizure Prediction

NeurIPS 2025spotlight

Precise, generalizable subject-agnostic seizure prediction (SASP) remains a fundamental challenge due to the intrinsic complexity and significant spectral variability of electrophysiologial signals across individuals and recording modalities. We propose \model{FAPEX}, a novel architecture that intro…
