This morning, I finished reading the book Blink: The Power of Thinking Without Thinking by Malcolm Gladwell, which I started reading on April 30 and bought on April 19. An interesting book, but somehow it overlaps with the Dutch book Het slimme onbewuste: denken met gevoel by Ap Dijksterhuis, which I read in 2014. In one of the last chapters, the book even mentions research done by Ap Dijksterhuis. I found the discussion on autism and and the ability to read the facial expression of emotions. It seems that some research is indicating that people with faceblindness are processing faces with the part of the brain that normal people use, but with the part for recognizing objects. I realized that people with faceblindness might also have a problem with recognizing emotions in facial expressions. I noticed that I had some problems with recognizing emotions on the Are There Universal Facial Expressions? test, although that once I knew the correct answer, it became clear to me. I experienced the same when watching some video's about microexpressions.

Denver DCH-330

Yesterday, I got Denver DCH-330 drone as a present from my employer for having worked for the company for fifteen years. Today, I came by car to the office and also brought a monitor and a box that I had taken home from TkkrLab before the space moved in February. I left the drone at the space, hoping that someone would have more fun with than I. To be honest, I am a little afraid to fly the thing. It does have a camera, but it can only record to a micro-SD card, but someone remarked that could be fixed. I told people that they should ask permission before performing some hacking on it.

Robotic Couture

I attended the opening of the exhibition Robotic Couture at TETEM art space. I arrived a little after five in the afternoon. It was not very busy. It took some time before Anouk Wipprecht held the opening speech, because she had to wait before a young lady was ready with putting on the robotic cocktail dress. Wipprecht spoke fast with a mixture of Dutch and English, not so strange, because she has been living in America for some years. She will stay in Enschede for the Maker Festival this weekend and give a talk on Saturday. I met several people from TkkrLab and looked around the exhibition. I did not consume one of the cocktails being produced by the cocktail dress.

The Future of Go Summit, Match One: Ke Jie & AlphaGo

I had set my alarm at four in the morning. Shortly after half past four, I started followeing The Future of Go Summit, Match One: Ke Jie & AlphaGo when the first two moves had been played. I set my Go board on just left of the keyboard and copied the moves being played. I shortly followed the Chinese commentary, but could not make sense of it. It was nice for Haylee to do the second hour of commentaries. Shortly after six o'clock, LIVE AlphaGo [W] vs. Ke Jie 9p [B], Round 1: Commentary by Myungwan Kim 9p came on. I followed it a bit, until they started to replay the game from the start. Around 7:21, Myungwan Kim concluded that Kie Ji is about five points behind and that the game is coming to a close.

An announcement move

Yesterday, I got up early again, and watched the second Go match between Ke Jie and AlphaGo. Ke Jie played an almost perfect game for the first hunderd moves (according to the winning chance calculations of AlphaGo). Afterwards Ke Jie told that he was taken over by his emotions in the second half of the game, after a very complex situation had been created on the board, what I would describe as total go, where all the stones on the board where somehow connected and involved in the fight. At some point there were eight unsettled groups, which is an unheard of high number. Ke Jie, quit suddenly it seemed, resigned at the start of the end game. He must have concluded that his position was hopeless.

Today, I did not get up early, and when I opened the live channel, it was at the start of the end game between AlphaGo and five Chinese professional players. I did not follow the game in great detail. But suddenly, I heard the two female commentators calling a move of AlphaGo "an announcement move". When, I noticed that AlphaGo had played an empty triangle move, a had to laugh out loud. All beginners are being told that the empty triangle is a very bad shape and that if they could simple avoid playing it, they would immediately jump in strength. It is a move with which AlphaGo says: I am so sure of my victory and I just play a very stupid move to let you know. About three minutes later, the team of Chinese professionals, resigned. Of course, AlphaGo did not play this move with the suggested intention. Actually, it is not able to internally verbalize such reasoning, let alone do it on purpose. AlphaGo is trained to maximize its chance of winning, not to win with the largest possible margin, which means that if it is ahead with more than the smallest possible margin for winning, it starts to play moves to reduce the margin if those moves according to many Monte Carlo playouts give a higher win chance. When we humans, who are not able to perform all those thousands of playouts, have to learn a game like go, we do this by verbalizing all kinds of rule of thump. Some are simple and others are had to grasp. We find enjoyment in grasping the rules, in getting a deep grasp of the game. This immediatly shows the big difference between deep learning networks like the one used in AlphaGo and our minds. In our brains there are neural networks with similar or even more powerful capabilities, but they mostly implement unconscious data processing. We can pick a familiar face out of a crowd in a blink of a second, sometimes we even have to search with our eyes to find the face to affirm it was indeed someone we know. We play games like go primarily with the more higher, more conscious parts of our brain.

Rob Scholte

I went to the lunch interview/discussion with Rob Scholte about his work on the How on earth should this be art exhibition at Concordia in Enschede. There were also some young ladies who were studying to be art teachers, who raised some interesting questions. Afterwards, I shortly talked with Rob Scholte and discovered that he knows Peter Struycken as well.

Bookshops in Utrecht

From the railway station, I walked through the streets Voor Clarenburg and Mariastraat to bookshop De Wijze Kater. I just paid a short visit and only looked at some singing bowls. Next I went to bookshop Steven Sterk and spend some time looking around. At last, I visited Broese Boekverkopers. There again, I only looked around.
