​Memory is Reconstructed, Not Retrieved: Graph Memory for LLM Agents

​https://arxiv.org/abs/2606.06036

​"Despite recent progress, LLM agents still struggle with reasoning over long interaction histories. While current memory-augmented agents rely on a static retrieve-then-reason paradigm, this rigid pipeline design prevents them from dynamically adapting memory access to intermediate evidence discovered during inference. To bridge this gap, we propose MRAgent, a framework that combines an associative memory graph with an active reconstruction mechanism. We represent memory as a Cue-Tag-Content graph, where associative tags serve as semantic bridges connecting fine-grained cues to memory contents. Operating on this structure, our active reconstruction mechanism integrates LLM reasoning directly into memory access, allowing the agent to iteratively explore and prune retrieval paths based on accumulated evidence. This ensures that memory retrieval is dynamically adapted to the reasoning context while avoiding combinatorial explosion caused by unconstrained expansion. Experiments on the LoCoMo benchmark and LongMemEval benchmark demonstrate significant improvements over strong baselines (up to 23%), while substantially reducing token and runtime cost, highlighting the effectiveness of active and associative reconstruction for long-horizon memory reasoning."

​What are the group goals? Stay on top of AI research, improve understanding of AI fundamentals+math.

​Who is welcome? Everyone! Try to put in at least some time on the paper and come prepared with questions or things you'd like to discuss, but it's ok to just show up.

​How will it work? Ideally everyone shows up and has at least made one solid pass through the paper, and then we can spend 60 minutes as a group going over it.

​This event is hosted at the Frontier Tower:

​We are transforming a 16-floor tower in San Francisco into a self-governed vertical village—a hub for frontier technologies and creative arts. Tier-one labs presenting AI, Ethereum, biotech, neuroscience, longevity, robotics, makerspace, human flourishing, and arts & music. These floors will house innovators and creators pushing the boundaries of human potential in a post-AI-singularity world.
