Learning What to Share and What to Personalize: Hierarchical Strategy Co-Evolution for Agent Memory

Memory-augmented agents maintain compact user profiles throughout extended conversations, enabling personalized and consistent responses without the need to process the entire dialogue history. The quality of these user profiles relies on the underlying memory management strategy: at each step, the agent must determine...

MemLife: Curating and Reasoning over Long-Term Egocentric Video Memories

Long-term egocentric video enables personalized AI assistants to reason about daily life. However, as video histories grow to hundreds of hours spanning months or years, reprocessing raw clips for every query becomes computationally prohibitive. Memory systems offer a scalable alternative by compacting videos into text...

Function Over Form: Distributional Orthogonalization in Mixture-of-Experts with Replica Expert Mechanism

This paper proposes Distributional Orthogonalization Loss (DO-loss), an auxiliary regularization that shifts the focus from static weight diversity to dynamic routing behavior, and introduces the Replica Expert Mechanism (REM), which improves load balancing through a two-tiered strategy.

Trust, but Verify: Uncertainty-Driven Evidential Multimodal Representation Learning

This work proposes Adaptive Evidential Multimodal Representation Learning (AEMRL), a framework aligned with this multi-level view of uncertainty that consistently enhances task accuracy, reduces calibration error, and improves robustness to noise, semantic conflict, and missing modalities.

Meta-Task: Turning Terminal Task Synthesis into a Terminal Task for Scalable Agent Training

Meta-Task is proposed, a framework that redefines terminal task synthesis as a Terminal-Bench-format task itself: an agent operates within a real container environment to iteratively generate, execute, and verify tasks, so that synthesized components are checked for internal consistency and executability within the gen...
