LASER: Learning Active Sensing for Continuum Field Reconstruction

Huayu Deng, Jinghui Zhong, Xiangming Zhu, Xiaokang Yang, Yunbo Wang

A reinforcement learning policy trained inside a latent model of physical dynamics can adapt sensor movements to reconstruct continuum fields from sparse measurements more accurately than fixed layouts.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

LASER consistently outperforms static and offline-optimized strategies, achieving high-fidelity reconstruction under sparsity across diverse continuum fields.

C2weakest assumption

That the learned continuum field latent world model provides sufficiently accurate intrinsic reward feedback and 'what-if' predictions to train a policy that transfers to real sensing scenarios.

C3one line summary

LASER trains a reinforcement learning policy inside a latent dynamics model to choose sensor placements that improve reconstruction of continuum fields under sparsity.
