Automatically Inferring Data Quality for Spatiotemporal Forecasting

Sungyong Seo, Arash Mohegh, George Ban-Weiss, Yan Liu
2018 International Conference on Learning Representations  
In this paper, we propose a novel solution that can automatically infer data quality levels of different sources through local variations of spatiotemporal signals without explicit labels.  ...  Spatiotemporal forecasting has become an increasingly important prediction task in machine learning and statistics due to its vast applications, such as climate modeling, traffic prediction, video caching  ...  We thank Michael Tsang for discussion and his comments that greatly improved the manuscript.  ...

Spatiotemporal deep learning model for citywide air pollution interpolation and prediction [article]

Van-Duc Le, Tien-Cuong Bui, Sang Kyun Cha
2019 arXiv   pre-print
Recently, air pollution is one of the most concerns for big cities. Predicting air quality for any regions and at any time is a critical requirement of urban citizens.  ...  Specially, we introduce how to transform the air pollution data into sequences of images which leverages the using of ConvLSTM model to interpolate and predict air quality for the entire city at the same  ...  If the error is small then we can infer that other spatiotemporal data has a remarkable effect on air pollution interpolation.  ...
