چکیده مقاله:
In this paper, the multivariate adaptive regression splines (MARS) is employed to predict earthquake events based on two common approaches in sequence learning. In the first scenario, the task is definedas a sequence prediction problem, and consequently the MARS model is used as a predictor. In thesecond scenario, the same task is considered as a sequence recognition problem and the model of MARS, this time, is used as a binary classifier with results that could alternatively help to predict an earthquake event. Forecasting results of applying the methods to a cluster of seismic data on pacificring of fire indicate that MARS as a binary classifier outperforms the predictor MARS. In fact, while both approaches are plausible, the best results are achieved when the earthquake prediction problem is considered as a sequence recognition task
