Artificial Intelligence in the Real World

We provide operational consulting in artificial intelligence (AI) for multimedia solutions including feasibility assessment, due diligence, and technology watch. We aim at removing the R&D risk from clients and brings back a working prototype that matches the business needs.

We mean artificial intelligence in the broadest sense: Mathematics applied with computers also known as statistical learning, pattern recognition, machine learning, signal processing for various media such as sound, image, video, text and of course tabular data.

Our expertise in artificial intelligence was earned through both academic research and corporate experience. Knowing how to combine the best of both worlds is the special signature. We mobilize and create cutting-edge research enhanced by concrete pragmatism to make sure our solutions work in the real world.

Research from Academia and Pragmatism from Companies

Our ambition translates into accomplishments towards artificial intelligence by maintaining close relationships with academia with scientific publications and collaborations, think tanks, companies thanks to research, operational consulting and teaching in business school.

Scientific Publications on Google Scholar

Scientific culture is at the core of our philosophy. We rove across the fields and never hesitate to deploy alternative approaches borrowed from non-AI domains discipline when they work more efficiently.

We believe that Artificial Intelligence (AI) should be understood as an upheaval comparable to agriculture and sedentary life, the invention of writing or even printing. Those turning points altered our very relationship to the world.

All activities are now being affected by AI. For our everyday life, artificial intelligence is the automated emergence of certain aspects of natural intelligence such as learning, decision making, adaptation, prediction etc.

In practice, artificial intelligence is the science that allows machines to execute tasks from examples instead of instructions.
