 Okay so first of all thank you for all being here this morning. I think this is the a very good opportunity to listen to to outstanding speakers. This is the third edition of our Hawaii Yahshua's workshop. As you know since more than two years now we've been doing in every year mostly in April a workshop where we gather the best mathematicians of Yahshua but also more broadly around the region of Paris-Saclet and also around Hawaii to discuss I would say new topics emerging in the field of ICT. This year we had a discussion with Emmanuel and we decided that of course as you know with the big hype that is going on around now with machine learning and AI to focus the workshop this year around the topic of AI in general and more specifically to ICT. Rapidly for for people who don't know I know there's a lot of people here coming also outside Hawaii you have to know that Hawaii is one of the leading companies in the ICT industry working in major in three sectors one as you may know is the case of mobile phones and I think you're all familiar with our mobile phone and logos are going around in our places the second is what we call the infrastructure where we sell base station that you have antennas and others and the other is of course the world of enterprise where basically all the telephones that you have in companies are also data centers concern us. It turns out that since a couple of years many companies ICTs are going towards the fact that they want to have more and more intelligent networks and it turns out that's one of the purpose we're doing this workshop is to understand basically the need but also the breakthroughs that are being done at the moment in the field of algorithms and in the field of algorithms in AI and how they can be mapped into our industry and help of course improves our customer experience and also improve our industry. That's basically the global view of Hawaii and AI for people are interested we have a research center here in Paris located in Boulain Biancourt and the majority here of mathematicians come from that research center focused on three domains one is the domain of 5G mostly algorithms for 5G the second domain which is also very important for us is the domain of 4.5G and we have also many of our mathematicians working on improvement improving the I would say the telecommunication industry as it is now. The third one is around virtualization of network and we have many of our mathematicians working also on everything which is related to routine optimization problem and the third one which is very important and I'm very happy to have one of the representatives of our research center here is the domain of AI and machine learning where we have also a team working on the general topic of big data for telecom and you'll hear also one of the talks related to that this morning. I'll give on now the speech also to Emmanuel so he can introduce rapidly what is IHES and why we decided also to have some close collaboration with the IHES in two years. Thanks a lot and welcome to this third edition of Huawei IHES workshops so we have a I would say a long collaboration with Huawei's who started maybe eight years ago and we have to acknowledge a very long support from Huawei to our institution I think we share some values and IHES is a center for fundamental science I would say so we are very oriented to mathematics and theoretical physics we host a very large program of visitors more than 200 visitors every year staying an average of two month and a half at any at any moment we have maybe 50 visitors here and these visitors are coming from more than 60 nationalities for in the last five years for example so we have a very high level of expectation for the permanent staff so for example out of ten professor in mathematics high that IHES seven were awarded Fields Middle we have also the used to take risk in hiring people quite young the average age for hiring a permanent professor in math here is 41 so it's we try to have people doing their work here when they are young and we are not only selecting people when they did their career so we try to have this as a way of operating and so it's really a pleasure to have this edition with Huawei I think we did some very good jobs the last two workshops and the program today seems very very interesting in the very hot topic and so I'm very glad to welcome you today
