dark humor

Dark humor to lighten the mood

‘If the coronavirus doesn’t kill me, being stuck in the house with my wife for three weeks will.’ Tasteless or funny? Since the lockdown, the number of jokes concerning the current pandemic has grown day by day. And while some may take offense from this dark type of humor, others just use them as a laugh to pass the time. They might be tasteless, but for most it’s just a distraction from the current situation. While sitting at home and being separated from the world, we use humor to connect with others. No matter in […]

Neuralink, our new future?

Elon Musk has always been known as a man of revolutionary ideas, but the following idea might be the most revolutionary of them all. Last week on the 7th of May, he joined the Joe Rogan podcast. Here he revealed new details about his company Neuralink. The idea of this company is to implant very thin electrode wires in the human brain. In this way, it can cure almost any disease which has something to do with the brain. Furthermore, these devices would even allow us to communicate with each other without speaking. The technique […]

Is het coronavirus daadwerkelijk goed voor het milieu?

Al weken domineert COVID-19 het nieuws in Nederland. Maar naast alle verhalen over overvolle intensive cares, ondernemers die worstelen met de huidige maatregelen en gesloten grenzen lijkt er één lichtpuntje te zijn: de coronacrisis is goed voor het milieu. De natuur heeft even een momentje om op adem te komen. De foto’s van vissen in de grachten van Venetië en satelliet beelden van de verminderde uitstoot in China circuleren over het internet. Er is minder verkeer en de industrie staat op sommige plekken op pauze, al met al ziet het er goed uit voor Moeder […]

Chinook: world’s best checkers player

Checkers, the ancient game which was quite easy to learn, has been solved. Along with other classical games, such as Connect Four and Qubic, the game has been pronounced dead. It was killed by Jonathan Schaeffer, who made the computer checkers program ‘Chinook’. Besides that, he publicated, “Checkers is solved’, which is a mathematical proof showing that the game always results in a draw when neither player makes a mistake.   Checkers; how to play it More than 150 documented different variations of Checkers exist. Of those 150, only two versions have a large international […]

The math behind the coronavirus

At the moment we live in a big crisis, the corona crisis. Already more than one million people over the world are infected and more than 60,000 people died. A lot of countries are having big outbreaks and the health care is having capacity problems. This is also one the many articles which you probably have seen about the coronavirus. What distinguishes this article from the rest is that it will dive a lot deeper into the mathematical models which researchers use to forecast the spread of the coronavirus. It is of course extremely important […]

Should we be scared of algorithms?

The word ‘algorithm’ can be quite a scary word if one does not know what it actually means. But should we be scared of it? Nowadays, the word is much more frequently used than it was in the past. This is because artificial intelligence (AI) has had a huge rise in the last decade. Algorithms are the building blocks of everything you’re using to read this article. 

One definition of an algorithm is a set of steps to accomplish a task. Hence, you might have an algorithm for getting from home to school, for baking a cake or finding the perfect dress for your evening in the store. In computer science, an algorithm is a set of instructions that take an input, A, and provide an output, B, that changes the data involved in some way. So, all that algorithms are, is a set of basic mathematical instructions.

These algorithms are becoming an indispensable part of our lives. However, some view this as dangerous. For example, Elon Musk (@elonmusk) wrote on 12 Augustus 2017,


“If you’re not concerned about AI safety, you should be. Vastly more risk than North Korea.”

Besides this, there are many stories about AI having negative consequences:  police profiling that reinforces racial stereotypes 21st-century discrimination , acceptance algorithms that deny access despite rightful requesters, unfair rating system algorithms optimized for commercial gain and many other systems that reinforce inequality.

However, to declare that algorithms rule the world is a bit hyperbolic, even though the algorithms are being used more and more every day. This is due to the fact we use computers, laptops and our smartphones so much that they are playing an increasingly more important role in many aspects of our lives. To make all of these devices do anything, you have to write a computer program in which you tell the computer, step by step, exactly what you want it to do. When you are commanding the computer what to do, you also get to choose how it is going to execute it. This is where the algorithms come in. The algorithm is the basic tool used to get the job done. Nevertheless, this is not how all computer algorithms are designed. In this instance, we have the version described above, with unsupervised learning. This involves data representing situations without independent variables. Because of this, there is no need to know the results of each scenario to use for training, and patterns are simply discerned from the data, where all the data is used for training. Besides that, some algorithms allow computers to learn on their own. This is called supervised learning, which involves having data, based on scenarios or historical events, with both dependent and independent variables. The model is trained using this data with both features (dependent variables) and expected results (independent variables). It is then trained by showing the model the scenario and its corresponding result.

Thus meaning, there are uses for machine learning, including data mining and pattern recognition. For example, these mathematical creations determine what you see in your Instagram feed, what movies Netflix recommends you and what ads you see in your Gmail.

But are these algorithms is some way good or evil? As mathematical equations, they are not. However, both people with good and bad intentions can use and have used algorithms. For this, AI models are trained using datasets. The person training the algorithms can select the events that are used to train the models, which is called Feature Engineering. This ‘Feature Engineering’ can be done for many reasons. For example, it can allow algorithms to be used with limited or incomplete data. Besides that, it can improve training by using less or only relevant data. This can improve the accuracy of a model or simplify the maintenance of the model. On the other side, Feature Engineering cannot only bring us good things. It can introduce a bias to the data, which will most likely happen unintentionally. This bias is introduced by the people who select the data, but the technology itself does not have any bias. 

 

To summarize this, one can say that algorithms and AI do not have either morals or ethics, which makes it neither good nor evil. However, since the algorithms are a tool used by people, it can be misused by people. To stop the misuse of AI technology, spreading awareness of how to use it ethically is needed. The reason for this is because it is the people who have biases, morals and ethics. So, should we be scared of AI? No, we should not, but we should be aware that there are people who can and most likely will misuse it.

the optimal pace problem

The Optimal Pace

For professional athletes, the goal of running a marathon is to complete it as fast as possible. However, this does not mean that the athletes are running as hard as they can all the time, as one cannot maintain this pace the entire marathon. Hence they need to find a maintainable pace at which they finish the marathon as fast as possible: the optimal pace problem. It turns out that this very general problem is occurring far more often in normal day life and in business than most of us realise. Furthermore, it turns out […]

Is life a video game?

Reality is probably not what it seems. The simulation hypothesis proposes that all of reality, including the earth and the universe, is in fact, a computer simulation. This proposition is, in fact, based on fundamental principles of human reasoning. Billions of years have passed since the formation of the earth. Early carbon-based life forms have had compelling experiences, to say the least. Imagine for a second, that the senses we experience, the things we observe, are all but a simulation, in which we are the “sims”. Computational power is increasing at an unprecedented rate, unlike […]

Wees niet bang voor Dennis en Ellen

Ciara, Dennis en Ellen. Over het algemeen niet de namen die bijzondere emoties aanwakkeren, maar toch zijn ze al weken het onderwerp bij menig ‘koffiezetapparaat gesprek’. Wie de laatste tijd het nieuws heeft gevolgd, zal het vast niet ontgaan zijn dat Nederland geteisterd is door een aantal stormen. Dit is niet anders dan andere jaren, echter zijn de stormen door de stormnaamgeving wel een stuk beter te bespreken.   Sinds september 2019 heeft Nederland zich aangesloten aan een stormnamen systeem van EUMETNET, een netwerk van Europese Nationale Meteorologische Diensten. Nederland maakt deel uit van de […]

In other news

Lately, the front page of the Dutch newspapers has been dominated with burdensome news about the coronavirus, developments around Brexit or statements from Donald Trump. Yesterday, even a new story about the prosecution of Ridouan Taghi was featured on the NOS website. Although this is of course very relevant and important news, 2020 has had a lot of interesting and positive developments that are now overshadowed by articles surrounding the current number of deaths in China or other onerous reports. Therefore, I believe it is time to give some extra attention to a few promising […]

Musical roads

Rumble strips are small bumps in the side of the road to alert drivers when they stray away from the middle of the driveway. Especially for people driving long roads at night, such a strip can be a life-saving instrument. If a tired driver slowly drowses away, he or she will be aroused by the annoying sound that the car makes when driving over these sleeper lines. Also people that are paying attention to their phone instead of the road may be stirred up by the strips. Did you know, however, that in many countries, […]
