We propose DeltaMem, a framework that organizes experience memory into two independent residual trees, one storing goal-conditioned task experience as reusable skills and another for scene-level environment knowledge.
Implicationpartial
Directly stated in the abstract with clear description of the two-tree structure.
Verificationpartial
partial
Evidencepartial
For retrieval, a failure-penalized similarity scan locates the best match, reconstructing the full experience via root-to-match chain composition.
Implicationpartial
Directly stated in the abstract with specific retrieval mechanism details.
Verificationpartial

Evidencepartial
Experiments across diverse interactive environments show that DeltaMem consistently outperforms existing baselines.
Implicationpartial
Stated in the abstract as a result, but specific performance numbers are not provided in the excerpt.

Evidencepartial
An autonomous consolidation mechanism distills high-frequency paths into new root nodes, enabling the trees to self-organize from general heuristics to specialized variants.
Implicationpartial
Directly stated in the abstract with clear description of the mechanism.
Verificationpartial

Evidencepartial
However, storing experiences as independent, flat units leads to substantial redundancy and retrieval conflicts, as similar episodes repeat overlapping content and subtle scene variations cause retrieved memories to offer contradictory guidance.
Implicationpartial
Stated as a problem in the abstract, but not directly measured in the excerpt.

Evidencepartial
To address this, we introduce residual experience, positing that newly acquired experience is often an incremental variation of existing knowledge.
Implicationpartial
Directly stated in the abstract as a core concept.
