Parametric Memory Decoding for Zero-Shot Routing in LoRA-Based External Parametric Memory

arXiv:2607.04118v1 Announce Type: cross Abstract: With the rise of parametric memory, LoRA-based External Parametric Memory (EPM) has emerged as a modular solution, but existing routing methods often introduce additional training, deployment, and maintenance overhead. This raises a natural question: can a LoRA-based EPM bank be routed without maintaining an additional routing component? However, existing zero-shot LoRA routing methods still face two problems under the EPM setting: (1) their evaluations are scattered across different task settings rather than organized around EPM access, and (2

Why this matters
Why now

The proliferation of parametric memory and LoRA-based External Parametric Memory necessitates more efficient routing solutions, driving current research in zero-shot methods to reduce overhead.

Why it’s important

Improving zero-shot routing for LoRA-based EPM can significantly reduce the computational and maintenance burden of large AI models, accelerating their development and deployment.

What changes
