Spatial phenomena are not determined independently but are affected by temporal and spatial phenomena nearby. In particular, to predict phenomena, it is necessary to construct the model that can deal with temporal correlation as well as spatial one to handle these dependent features. In this study, the machine learning model that explicitly consider the spatio-temporal correlation of spatial phenomena is constructed. In particular, LSTM(long term short-term memory) which has recently enjoyed a great success in the field of deep-learning and proved to be very powerful in analyzing time series data was used for prediction. However, it is challenging problem to extend the LSTM model to the spatial dimension and perform spatio-temporal analysis. This study constructed the LSTM model that considers additional spatial correlation and verified the performance of the model.
