 Welcome here on the 13th edition of 15 times four, our Christmas edition, hi everyone! This is basically a chain of blocks, of course that's the name, they are also numbered and you can imagine them like pages in a book or journal. I really like the presentations first of all and just gathering people in the middle of the week, I think it's just great. We remember this because the relationship between these items or the association between these items creates a map or creates context in our mind. It's a very nice and open atmosphere, they are very interesting speakers and speeches and like just generally I like it, yeah, I'm really enjoying myself. So well organized, I mean there are other you know people also who do science communication but the way it's organized is really good. Or in this example when you type into Google or also use your keyboard on your phone, what is the next word that is likely to appear. This is also an unsupervised learning task. It's really varied and it's quite interesting, I don't get to be in touch with science so much anymore, so yeah for me it's like a great opportunity. You see it, it's like a game of hide and seek or peek-a-boo.
