Recently, the demands on the services that predict and deliver real-time spatial information, such as road-traffic volume, have been increasing.
Mobile IoT devices that collect data for these services cannot necessarily transmit all of these data because of the bandwidth limitation in mobile networks.
Some previous works have reduced the volume of data transmission while maintaining prediction accuracy by prioritizing data transmission based on data importance.
They used feature selection methods to extract data importance from the machine learning model for the prediction.
However, some feature selection methods may deteriorate the prediction accuracy because what feature selection method achieves the best prediction accuracy depends on what dataset is used.
Therefore, this work proposes a method to ensemble data importance extracted by multiple feature selection methods to reduce the deterioration of the prediction accuracy.
Evaluation with real-world datasets shows that the proposed system suppresses the deterioration of the prediction accuracy by using ensembled data importance. |
