物联网环境中的数据采集需高精度无噪声数据,但日常使用的低成本传感器常存在误差。现有深度学习模型因资源消耗大,难以部署于资源受限的物联网设备。本文提出面向日常生活传感器的校准框架SenDaL,首次利用神经网络实现低功耗设备的高效校准。SenDaL采用自底向上的训练方式,基于线性模型与深度学习模型的校准结果进行决策;自顶向下的推理过程独立判断,兼顾精度与速度。该框架兼容多种深度学习模型(如LSTM、Transformer),可根据设备资源动态选择最优模型。实验表明,在不同物联网环境和真实场景中,SenDaL在精度上超越现有深度学习方法,同时保持与线性模型相当的延迟和能耗。
原文摘要 · Abstract (English)
The collection of accurate and noise-free data is a crucial part of Internet of Things (IoT)-controlled environments. However, the data collected from various sensors in daily life often suffer from inaccuracies. Additionally, IoT-controlled devices with low-cost sensors lack sufficient hardware resources to employ conventional deep-learning models. To overcome this limitation, we propose sensors for daily life (SenDaL), the first framework that utilizes neural networks for calibrating low cost sensors. SenDaL introduces novel training and inference processes that enable it to achieve accuracy comparable to deep learning models while simultaneously preserving latency and energy consumption similar to linear models. SenDaL is first trained in a bottom-up manner, making decisions based on calibration results from both linear and deep learning models. Once both models are trained, SenDaL makes independent decisions through a top-down inference process, ensuring accuracy and inference speed. Furthermore, SenDaL can select the optimal deep learning model according to the resources of the IoT devices because it is compatible with various deep learning models, such as long short-term memory-based and Transformer-based models. We have verified that SenDaL outperforms existing deep learning models in terms of accuracy, latency, and energy efficiency through experiments conducted in different IoT environments and real-life scenarios.
