M.A.K.S: Multidimensional Access Knowledge Scoring for Long-Horizon LLM Agent Memory Management
Abstract
AI agents with long horizons suffer from fixed context window sizes that necessitate memory evictions over time. Current techniques such as FIFO, LRU, and attention-based evictions use a binary approach to manage memory by either retaining or irreversibly deleting data. No current system preserves its evicted memories for later recovery, nor do any of the systems use multiple criteria to determine the value of memories. M.A.K.S., which stands for Multidimensional Access Knowledge Scoring, is a memory management technique designed specifically for LLM agent systems. M.A.K.S uses a continuous memory lifecycle consisting of degradation and revivals to address the issue. Each memory has an associated priority score denoted by S(t) that takes into account several factors including temporal degradation, access frequency, centrality, Shannon Entropy, and spaced reinforcement. To assess M.A.K.S, we conducted three experiments. Through the experiment called the Needle in a Compressed Haystack, we show that M.A.K.S was able to successfully reconsolidate a very important memory fact with a token usage ratio of 4.58× where FIFO memory evictions failed completely. The ablation experiment corroborates the inclusion of the Ghost Zone and reconsolidation pipeline in architectural support structures. Overhead benchmarking proves that lazy evaluation improves sweep performance up to 9.25× faster with 5,000 memory units, ensuring that scores remain less than 1% of LLM inference latency. M.A.K.S shows that memory management of AI agents is a first-class systems issue involving scoreable degradation, cold storage, and cue-based revival – not simple eviction.
