Recently, with the rise of the popularity of wearable devices like smartphones, it is becoming possible to use user’s moving records as a part of big data. In previous research, user movements were modeled by Bi-directional LSTM trained with time series of Mesh-ID. However, since Mesh-ID was assigned artificially, its physical distance and relative position were not considered properly. Therefore, it might be difficult to train the model effectively by using only Mesh-ID. In this research, to solve this problem, we used additional latitude and longitude information in the new model. As a result, we confirmed the accuracy improvement for Mesh-ID prediction and the difference between the output of clustering with user embeddings for each model.
