The Workshop series started back in 1990 in Lyon (France) under the different acronym of AIHENP standing for Artificial Intelligence in High Energy and Nuclear Physics. It was set to discuss the benefits recent advances in computing sciences in "Artificial Intelligence" could bring to this research field. More precisely, the question raised was "How computers can achieve tasks occurring in research going beyond mere numerical computations ?"

In the second session (1992 in La Londe Les Maures, France), one a the very first presentation of the World Wide Web concept before a wide and international audience was given by Tim Berners-Lee. But the workshop series helped many other ideas to emerge in event filtering (neural nets and genetic algorithm), in user graphic interfaces, in data analysis or automated cross-section computations.

The workshops organized every 16 months were held then successively in Germany, Italy, Switzerland, Greece, US, Russia, Japan, Germany again and The Netherlands in 2007. Since the US event, the series switched its acronym to ACAT to emphasis the growing importance of tools and infrastructures for data analysis and to open its scope to a wider field of applications.

Proceedings have been published by the CNRS editions, World Scientific, Elsevier Nuclear Instruments and Methods A and the Proceedings of Science.

Organizing formal and informal discussions is the main raison d'être of the workshop. Back in 1990, it was important to gather people working in similar or related fields, but having no easy means to exchange and confront ideas and results. Nowadays, researchers often clustered in large experiments have little opportunities to meet their colleagues in other big experiments. The workshop series is meant to overcome both pitfalls for the sake of a more efficient research.
