ML-based EStimator for ground-shaking maps (MLESmap)

The MLESmap is a novel ML-based methodology to generate ground motion shaking maps at the speed of the traditional empirical ground motion prediction equations. The first prototype of MLESmap has been developed and tested using one of the largest synthetic datasets generated by the CyberShake software for the Southern California. The MLESmap methodology is currently being generalized to act as a full workflow including an offline and online phase. We are using PyCOMPSs to optimize the data extraction and merging step. As an ML engine, the dislib software is used to generate the models and the inferences of the MLESmap
