摘要:

低成本颗粒物传感器正在改变空气质量监测,因为与参考监测器相比,它们具有更低的成本和更大的移动性。这些低成本传感器的校准需要来自共同部署的参考监测器的训练数据。基于机器学习的校准提供比传统技术更好的性能,但需要来自传感器的大量训练数据,以与参考监视器共同部署来校准。在这项工作中,我们提出了新的迁移学习方法快速校准的传感器与最小的共同部署与参考监视器。迁移学习利用来自其他传感器的大量数据以及来自目标传感器的有限量的数据。我们广泛的实验发现,所提出的基于模型不可知元学习(MAML)的迁移学习方法是最有效的其他竞争基准。

英文摘要:

Low-cost particulate matter sensors are transforming air quality monitoring because they have lower costs and greater mobility as compared to reference monitors. Calibration of these low-cost sensors requires training data from co-deployed reference monitors. Machine Learning based calibration gives better performance than conventional techniques, but requires a large amount of training data from the sensor, to be calibrated, co-deployed with a reference monitor. In this work, we propose novel transfer learning methods for quick calibration of sensors with minimal co-deployment with reference monitors. Transfer learning utilizes a large amount of data from other sensors along with a limited amount of data from the target sensor. Our extensive experimentation finds the proposed Model-Agnostic- Meta-Learning (MAML) based transfer learning method to be the most effective over other competitive baselines.
