Memory Beyond Recall: A Dual-Process Cognitive Memory System for Self-Evolving LLM Agents

Researchers propose DCPM, a dual-process cognitive memory system for LLM agents that organizes memory hierarchically from raw inputs to cross-domain patterns. The system uses a synchronous writer to record belief revisions and an asynchronous engine to induce schemas and detect cross-domain patterns, achieving significant improvements on personalization benchmarks requiring implicit reasoning about user evolution.

MEDLEY-BENCH: Scale Buys Evaluation but Not Control in AI Metacognition

Researchers introduced MEDLEY-BENCH, a new AI benchmark that evaluates metacognition—an AI model's ability to monitor and revise its own reasoning. The study found that while larger models evaluate their reasoning better, they don't actually control their outputs more effectively, and smaller models often match larger ones in metacognitive tasks, suggesting scale alone doesn't determine reasoning quality.

ClawArena: Benchmarking AI Agents in Evolving Information Environments

Researchers introduce ClawArena, a new benchmark for evaluating AI agents' ability to maintain accurate beliefs in evolving information environments with conflicting sources. The benchmark tests 64 scenarios across 8 professional domains, revealing significant performance gaps between different AI models and frameworks in handling dynamic belief revision and multi-source reasoning.

DeltaLogic: Minimal Premise Edits Reveal Belief-Revision Failures in Logical Reasoning Models

Researchers introduce DeltaLogic, a new benchmark that tests AI models' ability to revise their logical conclusions when presented with minimal changes to premises. The study reveals that language models like Qwen and Phi-4 struggle with belief revision even when they perform well on initial reasoning tasks, showing concerning inertia patterns where models fail to update conclusions when evidence changes.

The logic of KM belief update is contained in the logic of AGM belief revision

A new academic paper demonstrates that AGM belief revision logic contains KM belief update logic, showing that AGM belief revision can be viewed as a special case of KM belief update. The research uses modal logic with three operators to prove this theoretical relationship between two foundational frameworks in artificial intelligence reasoning.

Study on Quantitative Dynamic Epistemic Logic for Belief Revision

This academic paper presents a formal framework for belief revision using quantitative dynamic epistemic logic (DEL), extending AGM theory to capture degrees of conviction rather than binary belief states. The research formalizes belief revision processes within a modal logic system and proposes a new revision function that better aligns with philosophical intuitions behind AGM postulates.
