Our Lady, Waffles and Cake

According to my Mum, I was due already in February. However, there was no doctor around when the labour started why the nurses gave her some sedatives to slow it down. Not only did it slow down but it stopped completely why they send her back home. After a month she called them and asked if they perhaps should do something about it. While they were thinking about what to do, the situation suddenly got serious and in the end they had to make an unplanned caesarean. Obviously, both mother and child survived but I'm a bit sad that I caused her so much trouble. I think that few mothers would like to go an extra month.

It's a mixed blessing to have March 25 as your birthday. In Sweden it coincides with the celebration of the Waffle Day. The story goes that the Swedish term "våffeldagen" sounds like "vårfrudagen" which is the equivalent of "Our Lady's Day". Not only is this day nine months after Midsummer, it is also nine months before Christmas. It should be noted that Swedish waffles (often soggy and shaped like hearts) do not look like Belgian ones (crisp squares) and should be eaten with whipped cream and jam made by raspberries, blueberries and/or strawberries.

I've always been envious of my sister who was born in July (and some years ago she got the best birthday present ever, namely her son David but that's another story). It's much easier to have a birthday party in summer. So this year I've decided that I'll have that too. Well, perhaps not so much a party as a traditional Swedish "fika", with coffee and tea, biscuits and cake. I've booked the clubhouse Finnsjögården in Mölnlycke Sunday August 21 and hope for a warm and sunny afternoon. Bring your walking/running shoes and swimsuit and I'll provide you with some energy to use them. Send me an email to let me know you're coming. Welcome!

Deep Learning

When I was a PhD student in Educational Research, one of the most important pedagogical concepts imprinted on us (for both theoretical and practical reasons) was the notion of "deep learning". This concept was developed by professors Marton and Säljö in the late 70-ies and I believe it's spread among at least Swedish teachers. They noticed two different approaches to learning among students: those who adopted a "deep" approach to learning and engaged in an active search for meaning, and those who choosed a "surface" approach focusing on memorizing the parts of the material they thought they might be questioned about later.

The Wikipedia entry for deep learning leads to the more recent concept of a certain part of a broader family of machine learning methods based on learning representations of data. The approach is founded on going through heaps of data, through using multiple levels of representations in order to find patterns. This is very far from the pedagogical concept, why it makes me a bit confused.

What the two uses have in common is the association with depth as a positive aspect when it comes to learning. To have a deep knowledge of something is often considered good, even if it sometimes can lead to you becoming a nerd. However, very few people I know would like to be considered as shallow.

From Berlin 2015

Some consider "deep learning" to be nothing more than a re-branding of neural networks. Wired stated that 2015 was the year when Artifical Intelligence finally entered the everyday world, pointing at examples such as Facebook’s face recognition, Microsoft’s Skype translation, Google’s Android voice recognition and improvement of it's search engine, and Twitter's pornography identification (to give the users a chance to block it).

The hype was reinforced by Google going on a shopping spree buying the London-based DeepMind and the Oxford University spin-off companies Dark Blue Labs and Vision Factory in 2014. It's collection of many machine learning researchers made several people raise their eybrows, among them Antonio Regalado, senior editor for biomedicine for MIT Technology Review:

"Certainly, large companies wouldn’t be spending so heavily to monopolize talent in artificial intelligence unless they believed that these computer brains will give them a powerful edge. It may sound like a movie plot, but perhaps it’s even time to wonder what the first company in possession of a true AI would do with the power that it provided." 

At least one prominent researcher has kept a foot in academia: Yann LeCun. He is the head of the Artificial Intelligence Research Lab at Facebook and professor at New York University. He takes his role as “public intellectual” seriously and often speak about his work, as in this interview for the IEEE Spectrum journal. 

What might become a nice combination of the two uses of "deep learning" is the recent development when it comes to open source in this area. Google has provided access to the software engine that drives its deep learning services and Facebook has open sourced designs for the custom-built hardware server that drives its deep learning work. Elon Musk has launched the nonprofit initiative OpenAI.

Google is also offering a free online class about deep learning. It would of course be interesting to see what kind of learning approach the students take on that subject and what kind of teaching approach is used.

Meanwhile the debate is still ongoing regarding to what extent machine learning should try to mimic human learning and if it's possible to make computers truly understand human language. Well, since it's not obvious if we humans understand anything at all or each other, it may take a while.

A Short Story About Long Reads

I'm the first person to admit that my PhD thesis was way too long. I've not met one single person who has read it in total (including the evaluation committee and my supervisor) with the possible exception of my very thorough opponent Professor Mike Spector.

Already robots are creating short pieces for newspapers. An article from The Guardian in 2014 lists quite a number of various softwares providing this kind of service such as Quill, Wordsmith, Yseop and Labsense. With journalists being laid off (as a result of the difficulty of finding good business models handling free journals and the online generation) it's no wonder the future for in-depth material looks glum.

From Stråvalla 2015

However, it seems to me that the material the robots provide is focusing on well-structured settings such as reporting on sports, ratings, finance and so on. It would be rather fun to create software that takes annual reports from companies and cut through the corporate bullshit and presents the material in a way that makes sense and really spells out what's going on. Another application would be software that checks what politicians say and compares it to what they claimed some years ago, especially the difference between pre and post election statements. Perhaps another area would be gossip reporting from events such the Academy Awards (congratulations Alicia Vikander!). I shouldn't have given up my career in computational linguistics...

As an antidote it good to see that websites focusing on collecting and distributing in-depth material is on the rise. One of them is Longreads and another one is Longform. Here you can find new material such as "Life and Death in the App Store", but also old classics like Harper Lee's first article "Love - In Other Words" from 1961. However, wouldn't it be just cynical if the compilation of the long reads was made by a robot!?! Of course, you could argue that editing is a dirty, dull and dangerous job.

However, in our stressed-out world with activity-based offices and time to read only on the bus and using your smartphone, how can we submerge ourselves in a long read? Maybe this new kind of café is the answer, where you are not allowed to speak. I wonder if we'll get something like that at Chalmers, now that our new President has declared that all new offices will have an activity-based design.

Friends and Photos

The photo competition is over for this year and the winner is Anette Carlsson! Congratulations! She voted for the picture of me standing in a field of wheat on the island Ven, which also was the one that most people liked.

From Photo Competition 2015

My mother took the photo and I must point out that I didn't damage any of the crops, since I stepped in the tractor tracks. When we biked around the island, I saw this opportunity for a shot a bit similar to the Gladiator movie when Maximus dreams about his home in Spain. However, I don't claim any other similarities between Russell Crowe and me. Unless you count a love for Australia. The country, not the movie, although I like that too but I don't know about him. That is, I don't know if he likes the film. I like him though. And Hugh Jackman.


I'm very grateful for my friends all over the world and all the fun things we've done together: skiing, going for walks and to the beach, camping, dinners, canoeing, traveling, visiting museums and gardens, singing, playing volleyball, and much more. I wish I had more photos from such occasions! Here is one at least from the walk at Billingen last year with my Mum and Anette.

From Easter 2015

It's rather popular to tag your friends in Facebook but you might want to be careful. Automatic face recognition software is not only becoming more sophisticated, but also more common (cheap). Facebook and Google are at the forefront. Casinos, airports and the police have been using it for a while, next it catches your shopping spree. Even if it would be nice to get more photos of me together with my friends using this kind of technology, I'm not prepared to give up that much privacy. What do you think?

Squirrel Imprint

There were pine trees outside the house were I grew up in Mölnlycke and occasionally you could see red squirrels playing in them. Later the trees were cut down to make way for a new house next doors and a better road. I really missed those squirrels.

Maybe that's why I'm still so fond of squirrels. I know it's true what I said back in 2007: "Everyday I see a squirrel is a happy day!" Since that was written after a trip to Brookfield outside Atlanta, I suspect that what I really referred to were chipmunks (in Swedish "jordekorre" which translates into "earth squirrel" and I know that they are not squirrels).

However, it could have been the Eastern Gray Squirrel, although I have seen more of them in the UK than in the US. I remember seeing them in Regent's Park on one of my frequent visits to London. According to research, the spread throughout the UK is still very much the result of human intervention.

From London Spring 2008

During a trip to Kingston in Canada in 2006, I came across a black squirrel for the first time. I didn't have a decent camera at that time (although I used my at that time advanced mobile phone to get some snaps of the city), why I have to rely on memory.

Squirrels are often associated with hoarding or in a more positive way, making sure you have enough when/if bad times hit you. I recently told my uncle that I'm the squirrel when it comes to saving things from the family past, hoping that sometime my now young relatives will become interested in them and have the space to harbour them.

In Swedish we sometimes talk about being stuck in an "ekorrhjul" (squirrel wheel=treadmill). I try not to think in that way, although lately it has been a challenge and I've felt more like U2's "Stuck in a Moment".

The squirrel Ratatoskr played a role in Norse mythology as a messenger between the eagle at the top of the world tree Yggdrasil and the dragon dwelling at the roots. Apparently it was more into gossip and saying nasty things. Not a good role model!

I still like them though, and I put up a special feeder to provide nuts during the winter. For Christmas I bought a coaster with a squirrel and a "tomte" at the Christmas Fair at Tjolöholm Castle. The painter Jan Bergerlind is a master at capturing the right "old times" feeling!

Dirty, Dull, and Dangerous

No, it's not me I try to describe (come to thing of it, it can be a proper description when I kill slugs). Apparently, this is the job description for robots. At a recent Swedish conference on robotics professor Danica Kragic Jensfelt talked about the drivers behind the development in different countries. She also made us rest assured that washing up after dinner by hand is a job we never need to be afraid of loosing out on to robots...

There is no surprise that the US is driving the development of robots for military applications. Japan seems to focus more on developing help to manage the aging population there. In Europe robotic support in industrial processes by robots has been a topic for a while.

I can't help but thinking that maybe what is considered dirty, dull and dangerous also varies among people from different cultures. It's probably a gender issue as well. Interestingly, friends of mine named their automower Bo-Astrid, probably reflecting that both of them, man and wife, used to do the mowing before. There is some research on this too. According to a study made in 2008, people tend to want robots to do work that require memorization, keen perceptual abilities, and service-orientation. At the same time, they prefer people in occupations that require artistry, evaluation, judgment and diplomacy.

I'm not sure if that's because they think people are better at theses tasks or if they are afraid of loosing the relatively fun jobs. No wonder that they also felt more positively toward robots doing jobs with people rather than in place of people. However, the list of quite interesting, not so dirty nor dangerous jobs that are predicted to be accomplished by robots in the near future is unnervingly long.

Long before robots were plentiful, the concept "dirty, dangerous and demeaning" was coined to describe certain kinds of jobs some of which are taken over by robots. I wonder when a job will be too demeaning for a robot?

Drones are often hailed as the solution to many dirty, dull and dangerous jobs. However, it seems that they are now facing another kind of danger: people (like me) wanting to shoot them down when they are hovering around taking pictures without your permission. I'm looking forward to when cheap versions of the DroneDefender from Battelle hit the market.

Robots can be cute as well. Wall-E is one of my favourite films all times. When accompanying my nephew to the Science Fiction Bookstore in Gothenburg, I found this amazing book on how to make crochet robots: Crobots. My ambition is to make at least one! Mum, please help me!

What's Cooking?

Just around the corner from where my aunt lived in Chelsea was one of Gordon Ramsay's own restaurants. We somehow didn't get around booking a table there before she moved to Worthing.

Although there's a lot of shouting and swearing coming from Ramsay, I think of him as very much oriented towards strength-based development and sustainability. This is especially prominent in the shows where he tries to help hotel and restaurant owners. He is very committed to making a sustainable business where everyone is in position to do his or her best, although this sometimes means for some people to swap roles or step back. He tries to compose a manageable and profitable meny, often made from local food. He is dedicated to keeping the kitchen clean and not let things go to waste. He looks at how to make the most out of the building and tries to win the hearts of the local customers, providing a nice and relaxed atmosphere. No wonder he got an OBE for helping to develop the service profession (his charity work probably helped too).

From UK May 2013

There's an awfully lot of metaphors related to cooking. One of the most well known is of course "the boiling frog" parable.  However, it's not true that frogs stay in hot water and boil to death because (sadly) some scientists set out to test it.

Other examples are "you're toast", "the idea is only half-baked", "boil down to", "a recipe for disaster", "key ingredient", "too many cooks", "icing on the cake", "full plate", "sizzling with anticipation", and "food for thought". Many cooking-oriented metaphors are for some reason used in politics: "grill the candidates", "whip up a new policy", and "stir up trouble".

According to Tien Wong, differences between entrepreneurs can be compared to those between chefs. He claims that there are three kinds of chefs (using another set of metaphors): the scientist who in detail follows a very complicated recipe, the magician who finds inspiration in going to the market and then conjuring up a creation when coming back to the kitchen, and the artist who dosen’t work off an exact recipe, but instead relies on instinct and creativity to work within his themes.

From Höstmarknad sep 2014

He then moves on to giving examples of entrepreneurs who follows these three chef stereotypes. I agree with the analysis that the "artist entrepreneur" is probably most likely to succeed although it is the magicians such as Twitter, Google and Facebook that get most attention.

I wonder how to characterise Ramsay as an entrepreneur. I think he's mostly an artist, both as a chef and as an entrepreneur. At least he gets it right most of the time. In 2015, Forbes listed his earnings at $60 million for the previous 12 months, and ranked him the 21st highest earning celebrity in the world. Let's just hope in time he'll get a little more understanding towards vegetarians.
