Abstract
Despite the emergence of big data that contains plentiful spatiotemporal information, researchers are still facing the challenge that the acquired data after time slicing are insufficient to characterize the real heterogeneous spatial pattern. The problem becomes especially important in areas such as epidemiology and economy where the fine-resolution data are under intense demand. This paper introduces a novel approach named geo-propagation to propagate sampled data to unsampled locations incorporating semi-supervised learning under the graph context. A case study of estimating property price is shown to demonstrate the effectiveness of our proposed method.
