PreCoMem: Predictive Cognitive Memory for Self-Evolving Long-Term Dialogue Agents

Read the original on arXiv AI →

PreCoMem introduces a memory consolidation framework for long‑horizon dialogue agents, inspired by predictive coding. It represents user memory as confidence‑weighted beliefs and uses an Effective Surprisal signal to decide whether to maintain, profile, or correct each belief. Experiments on LoCoMo, LongMemEval‑S, PersonaMem‑v2, and the new DiMoBench demonstrate state‑of‑the‑art accuracy and robust adaptation to non‑stationary belief drift without over‑reacting to noise.

Beyond Memory: Harnessing Long-Horizon Agents with Explicit Belief States

Beyond Memory: Harnessing Long-Horizon Agents with Explicit Belief States introduces PoS, an inference-time framework that builds and maintains explicit belief states to guide large language model agents. Each belief state combines an estimate of the current world with unresolved task requirements, making clear what the agent still needs to learn and accomplish. PoS validates consistency, monitors task progress to detect Belief Trapping, and tailors recovery to the trapping pattern and unresolved requirements, achieving top performance across four benchmarks with all three LLM backbones.

Long-Term Agent Memory through Complementary Curation and Consolidation

The paper introduces a hybrid memory system for long-horizon dialogue agents that combines episodic memories with structured relational memories, supported by a consolidation mechanism to maintain efficiency. Experiments on the LoCoMo and LongMemEval-S benchmarks show that the two memory types complement each other, outperforming existing memory frameworks with 90.2% accuracy on LoCoMo and 85.5% on LongMemEval-S.
