To alleviate this issue, sensors are often configured to operate at relatively low sampling frequencies, yielding a reduced set of observations. Nevertheless, this can hamper dramatically subsequent decision-making, such as forecasting. To address this problem, in this work we evaluate short-term forecasting in highly underdetermined cases, i.e., the number of sensor streams is much higher than the number of observations. Several statistical, machine learning and neural network-based models are thoroughly examined with respect to the resulting forecasting accuracy on five different real-world datasets. The focus is given on a unified experimental protocol especially designed for short-term prediction of multiple time series at the IoT edge. The proposed framework can be considered as an important step towards establishing a solid forecasting strategy in resource constrained IoT applications.This work has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 957337 (project MARVEL) and the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH-CREATE-INNOVATE (project code: T1EDK-00070).http://creativecommons.org/licenses/by/4.0/1116-112030th European Signal Processing ConferenceEuropean Signal Processing Conference Tzagkarakis Christos Charalampidis Pavlos Roubakis Stylianos Fragkiadakis Alexandros Ioannidis Sotirios Ιωαννιδης Σωτηριος European Signal Processing Conference (EUSIPCO) Internet of Things Μachine learning Μultiple time series Νeural networks Rolling window tuning Short-term forecasting
