MemCode: Discrete Semantic Representations for Long-Term Agent Memory

Long-term memory remains a fundamental bottleneck for large language model (LLM) agents across sessions. Existing systems typically adopt a write-then-retrieve paradigm, storing context-dependent dialogue fragments and retrieving them via nearest-neighbor search in a continuous embedding space. This design yields unsta...

HeteroFL-LoRA: Federated LoRA Fine-Tuning Across Heterogeneous LFMs via Singular Value Collaboration

HeteroFL-LoRA is proposed, a federated framework that enables LoRA fine-tuning across heterogeneous LFMs and introduces a Singular Matrix–Guided Subspace Projection that employs singular matrices to achieve cross-subspace mapping, enabling heterogeneous clients to aggregate their LoRA updates in a unified representatio...

A Durable Machine Unlearning Framework to Nullify Recall of Sensitive Data on Incremental Training

The proposed DUE framework can effectively nullify the recall of sensitive information after MU, and even improve the performance of ULMs, and establishes a new fundamental research direction in safe training against MU vulnerabilities.
