Marginal Advantage Accumulation for Memory-Driven Agent Self-Evolution

arXiv:2606.20475v1 Announce Type: new Abstract: In batch-style trace distillation, the same memory operation may receive contradictory feedback across different batches. Existing methods lack a cross-batch, operation-level evidence accumulation mechanism, making it impossible to distinguish stably effective operations from accidental hits. This paper formalizes the requirement as two structural conditions, alignability and comparability, and proposes Marginal Advantage Accumulation (MAA). MAA constructs differential signals to make them comparable across batches, accumulates signed evidence pe

Why this matters
Why now

This research addresses a critical limitation in current batch-style trace distillation for AI agents, as the field matures and seeks more robust self-evolution mechanisms.

Why it’s important

Improving how AI agents learn and adapt across diverse experiences will accelerate their development, making them more capable, efficient, and reliable for complex tasks.

What changes

The proposed Marginal Advantage Accumulation (MAA) offers a novel mechanism for AI agents to more effectively learn and distinguish superior operational strategies, enhancing their self-improvement cycles.
