Language-Aided State Estimation
This addresses state estimation problems in domains like irrigation management by integrating human language data, though it appears incremental as it adapts existing particle filter methods.
The paper tackles state estimation for physical systems by using human observations expressed in natural language, proposing a Language-Aided Particle Filter (LAPF) and demonstrating its effectiveness in water level estimation for an irrigation canal.
Natural language data, such as text and speech, have become readily available through social networking services and chat platforms. By leveraging human observations expressed in natural language, this paper addresses the problem of state estimation for physical systems, in which humans act as sensing agents. To this end, we propose a Language-Aided Particle Filter (LAPF), a particle filter framework that structures human observations via natural language processing and incorporates them into the update step of the state estimation. Finally, the LAPF is applied to the water level estimation problem in an irrigation canal and its effectiveness is demonstrated.
