HABIT-Bench: Evaluating Habit Induction from Longitudinal Weak Evidence in Agent Memory

Junming Zhang, Rubin Wei, Xu Cheng +7

In long-term interactions with large language model (LLM) agents, users reveal habits through their choices and actions. These habits capture implicit user information that agents…

Search-G1: Co-Evolving Representation-Based Rewards for Selective Grounded Search

Ruoxi Cheng, Haoxuan Ma, Hongyi Zhang +7

Search-augmented language agents should retrieve external information only when necessary and ground their answers in retrieved evidence. Yet terminal correctness assigns equal cre…

Curvature-Aware Zeroth-Order Optimization for Memory-Efficient Test-Time Adaptation

Junming Zhang, Shuyu Yin, Peilin Liu +2

Test-time adaptation (TTA) aims to enhance the cross-domain performance of pre-trained models by adapting to unlabeled test data. While most existing TTA methods rely on backpropag…

Memory Decoder at Scale: A Pretrained, Parametric Long-Term Memory

Rubin Wei, Jiaqi Cao, Jiarui Wang +4

Decoder-only language models entangle long-term memory and reasoning in a single parameter set, making it difficult to scale memory capacity independently. Memory Decoder introduce…
