Predicting the Next Location: A Recurrent Model with Spatial and Temporal Contexts

Predicting the Next Location: A Recurrent Model with Spatial and Temporal Contexts

2016 | Qiang Liu, Shu Wu, Liang Wang, Tieniu Tan
The paper "Predicting the Next Location: A Recurrent Model with Spatial and Temporal Contexts" by Qiang Liu, Shu Wu, Liang Wang, and Tieniu Tan introduces a novel method called Spatial Temporal Recurrent Neural Networks (ST-RNN) for predicting the next location of a user. The authors address the limitations of existing methods such as Factorizing Personalized Markov Chain (FPMC) and Tensor Factorization (TF), which struggle with modeling continuous time intervals and geographical distances. ST-RNN extends the traditional Recurrent Neural Networks (RNN) by incorporating time-specific and distance-specific transition matrices, allowing it to model local temporal and spatial contexts more effectively. The model is evaluated on two datasets: the Global Terrorism Database (GTD) and the Gowalla dataset, showing significant improvements over state-of-the-art methods in terms of recall, F1-score, MAP, and AUC. The experimental results demonstrate that ST-RNN can better capture the impact of continuous time intervals and geographical distances, making it a more accurate and reliable method for location prediction.The paper "Predicting the Next Location: A Recurrent Model with Spatial and Temporal Contexts" by Qiang Liu, Shu Wu, Liang Wang, and Tieniu Tan introduces a novel method called Spatial Temporal Recurrent Neural Networks (ST-RNN) for predicting the next location of a user.
