Multi-View Kernels for Low-Dimensional Modeling of Seismic Events
This work addresses the need for reliable identification of man-made explosions in seismology, but it appears incremental as it applies existing kernel-fusion techniques to seismic data.
The paper tackles the problem of automatically identifying seismic event properties, such as type and location, by proposing a kernel-fusion based dimensionality reduction framework. It achieves promising results on 2023 events recorded in Israel and Jordan.
The problem of learning from seismic recordings has been studied for years. There is a growing interest in developing automatic mechanisms for identifying the properties of a seismic event. One main motivation is the ability have a reliable identification of man-made explosions. The availability of multiple high-dimensional observations has increased the use of machine learning techniques in a variety of fields. In this work, we propose to use a kernel-fusion based dimensionality reduction framework for generating meaningful seismic representations from raw data. The proposed method is tested on 2023 events that were recorded in Israel and in Jordan. The method achieves promising results in classification of event type as well as in estimating the location of the event. The proposed fusion and dimensionality reduction tools may be applied to other types of geophysical data.
