Multidisciplinary Institute in Artificial intelligence

DESCRIPTION

With our present day methodologies, the dynamics of the processes in Earth are still hidden in rapidly accumulating seismic and geodetic data. AI will bridge the gap between the amount of observations and the incomplete understanding of the processes.
New weak signals highlight the complex spatiotemporal evolution of the deformation. Our group is at the forefront for massive processing of seismological (passive imaging and monitoring) and geodetic data. Our goals are: the detection of known and new classes of signals, the disentanglement of the physical processes at work, the upscaling of our workflows.

ACTIVITIES

Multiscale representation of signals
Continuous records clustering
Detection with vector auto-regression
Ambient noise modeling
The applications cover the micro-earthquake detection and classification in mining and fluid injection environments and the improvement of ambient noise based imaging and monitoring, a technique developed in our group.
Our cross disciplinary group implement the tools of AI to handle the complexity and the imbrication of scales of the different interacting non-linear processes acting on the solid and fluid components of the actual medium.
