Calibration-First Reward-Component Auditing for Reinforcement Learning Control in Smart Greenhouses

Summary

A reproducible calibration-first reward audit framework is proposed for smart greenhouse reinforcement learning control, decomposing scalar reward into conditional temperature, CO2, humidity, and actuation terms, validated on GreenLight-Gym and Autonomous Greenhouse Challenge data.

Abstract:Greenhouse reinforcement learning can test climate-control ideas at a speed and scale that is difficult to achieve with crop experiments alone. For smart-greenhouse control, however, a single simulator return is not enough: a grower or control engineer also needs to know when the policy heats, enriches CO2, vents, manages humidity, deploys screens, or uses this http URL propose a reproducible calibration-first reward audit framework that keeps named greenhouse-control reward components comparable across simulator training, facility-adapted rollouts, logged Autonomous Greenhouse Challenge records, and actuator-rule distillation. In GreenLight-Gym, the framework decomposes the scalar reward into conditional temperature, CO2, humidity and vapor-pressure-deficit, screen, and actuation-proxy terms; adapts GreenLight to the second Autonomous Greenhouse Challenge logged climate traces; and scores the same components on logged greenhouse data.

Key points

  • The framework keeps greenhouse control reward components comparable across simulator training, facility-adapted rollouts, logged challenge records, and actuator-rule distillation.
  • In GreenLight-Gym, rewards are decomposed into temperature, CO2, humidity, VPD, screen, and actuation-proxy terms.
  • The framework adapts to the second Autonomous Greenhouse Challenge's logged climate traces and scores them.
