The laboratory was founded in 1991 and was the first group in CGDS. The work of the laboratory is concentrated towards the following main developments:

• artificial intelligence algorithms, their mathematical models and application to geophysical data studies;
• Internet-guided geosciences data resource.

Mathematical methods of artificial intelligence are the main stream of the work of the laboratory. The first studies in this field were started in 1991 by A. Gvishiani and M. Zhizhin in collaboration with French scientists J. Bonnin, B. Mohammadioun and D. Rouland (Institut de Physique du Globe de Paris). The core of the project was development of new syntactic pattern recognition technique and its application to seismic signal analysis. As a result of this project, which CGDS implemented in 1991-1995 jointly with French Atomic Energy Commission (CEA), the algorithm SPARS (Syntactic Pattern Recognition Scheme) was designed. It was successfully applied to recognition of geological region on the basis of strong ground motion records classification. Another application was syntactic classification of seismic records recorded by Geoscope Station. SPARS algorithm was further developed in 1995-1996. New it is widely used in Russia and France in different geophysical problems: volcanology, exploration and earthquake studies.
