Natural and Spiritual Efficiency

After the COVID-19-induced shift to home offices last year, I, an ardent advocate of on-site teaching and networking, quickly began appreciating the efficiency that working from a home office offers.

Python script to calculate one's h-Index per year

Here’s a small script I wrote, using Python, scholarly and Google scholar, to calculate one’s h-Index per year (so you can see how it evolved over your life as a researcher). It tells me in what periods of my career I have been most active in producing most ‘impactful’ research output. I missed such capability in otherwise great tools for citation analysis like Harzing’s Publish or Perish.

Great methodology delivers great theses

Adam Savage on science

I enjoy mentoring people and sharing my personal lessons learned. One of my key advices to become a (more) successful student and researcher with respect to writing excellent theses is to argue/reason well in your writeup: motivate your thoughts, justify your choices, and reason over your findings. As you not only make assertions or claims, but reason over their pros and cons and convince your reader by the power of argument (and references), you will position your work for highest accolades.

Advice for (prospective) students

Dear (prospective) ZHAW student, a very warm welcome to academia! You may just have entered the bachelor’s programme or “Fachstudium”, or you are already a mature engineer, ready to start your master’s or PhD studies - chances are you haven’t been exposed much yet to our setting of learning within an applied research and development context.

Algorithmic bias: important topic, problematic term

Recently, I engaged in a discussion within the Expert Group on Data Ethics on the pros and cons of the term “algorithmic bias”, which describes the fact that certain people groups might be discriminated by an automatic decision making system, and how to prevent this. While every research in this sphere is very important and rightly so at the forefront of current discussions in data science, artificial intelligence and digital ethics (see e.g. here, here or here), I think the term itself might do more harm than good in the public discussion.

SMEs and digitalization

What kind of digitalization support do SMEs need? This question was pondered on August 29 when Innosuisse assembled their experts, coaches, staff members and executives under the beautiful roof of CERN’s Globe of Science and Innovation for the Innosuisse Plenary 2018. The topic of innovation was omnipresent, and I had been invited as a representative of the Swiss Alliance for Data-Intensive Services to start the discussion in the breakout session on “digitalization and SMEs” with a keynote. I delivered some pointed hypotheses based on the experience of almost 2 years of Data+Service and numerous CTI/Innosuisse projects. A recording of the presentation is available online, together with the slides. The talk follows the important properties of digital innovations (namely, being interdisciplinary, aiming at automation at scale, and coming at a high speed). These are my conclusions, originally published on the Data+Service blog.

Lecture notes on Reinforcement Learning

I recently took David Silver’s online class on reinforcement learning (syllabus & slides and video lectures) to get a more solid understanding of his work at DeepMind on AlphaZero (paper and more explanatory blog post) etc. I enjoyed it as a very accessible yet practical introduction to RL. Here are the notes I took during the class.

Faith and science

There is a whole body of literature on the topic of faith and science (and a good example is the work of C.S. Lewis, even if it is a rather unorthodox specimen). Here’s another one, unorthodox in not attempting apologetics, but merely relaying a testimony in the sphere of science.

Some bits of theory to better understand deep learning

This is a collection of links to some interesting recent theoretical advances in order to better understand deep learning. It is not complete, not even comprehensive. It is more of a reading list for the upcoming Christmas holidays. More on the topic of deep learning theory can be found in this new MOOC by Stanford professors Hatef Monajemi, David Donoho and Vardan Papyan, in this DL theory class by Ioannis Mitliagkas of U Montreal, and in this overview blogpost by Dmytrii S. on why deep neural nets generalize so well. A good collection of links is also included in this blog post by Carlos Perez.

When to publish one's work

Coming to the end of a writing-heavy week with 5 paper deadlines, the experience from these publishing processes reinforced the three necessary conditions to me on when to publish (and on what to focus in the paper, besides the story line). When is my work advanced enough that I can publish it? When can I attempt not only writing it down (you should always do it as it clears one’s thoughts), but also making it accessible for the rest of the world (being aware of your responsibility for the body of human knowledge, the valuable time of potential readers, and your future reputation)?

Experimenting with Generative Adversarial Nets

Recently, I got intrigued by so-called Generative Adversarial Nets or GANs (see the original paper, the important improvement to make it practical, an easy to understand implementation and a nice application here). So much so that I derusted my programming and linux command line operation skills, learned docker, and started playing around myself for the first time in several month.

Scientific disciplines are foremost communities

For a young researcher the diversification in the academic landscape can be a huge challenge: am I interested / proficient in machine learning - or pattern recognition? Am I a computer vision guy (because I work mainly on images), or in the field of predictive maintenance (because I also worked on such tasks)? Am I a data miner because I mine data, and can I also add artificial intelligence to the list of my research interests just because I have published on its sub-field of machine learning?

Doing applied science

How to do science is a huge topic. I intent to treat it utterly wrong here by not giving it the depth it deserves. Rather, I want to summarize some key points that might be beneficial for students facing the challenge of writing a first scholarly thesis (“wissenschaftliche Arbeit”). As some of these students will have German as their first language, I will translate some important phrases.

On the use of examples in learning

Once in a while in a discussion on education or science, the topic of the perceived opposition of theory and practice comes up. It is usually raised by one party with a strong view on either a theory- or an application focus, with the goal of discrediting the other viewpoint: “This is just theory (and thus worthless), because what we need is to make it run”. In a classroom setting, you sometimes hear it from students complaining about too much abstract knowledge and too less examples.

Writing a draft

Every once in a while you have to write a draft for some sort of text, as a starting point for somebody to give feedback or improve upon it – maybe a short abstract, a chapter for a thesis or paper, an important email or a proposal. So, what makes up a good draft?

The role of novel ideas in neural network research & applications

Public opinion has it that the current success of deep learning is built upon ideas from the 1970s and 1980s, enhanced by the availability of (a) increased computational power and (b) “big” data. Some add that a few minor algorithmic improvements also have been involved (e.g. BatchNorm weight initialization [see also explanation here], ReLU [rectified linear unit] nonlinearities, dropout regularization, or the ADAM optimizer). Building deep neural networks, the legend goes on, then boils down to clever engineering of the knobs and faders of these “black boxes”; and nobody really understands why they work or how they produce results: Pure black magic at worst, empiricism instead of science at best.

Data scientists type A & B? Nonsense.

I recently came about the notion of “type A” and “type B” data scientists. While the “type A” is basically a trained statistician that has broadened his field towards modern use cases (“data science for people”), the same is true for “type B” (B for “build”, “data science for software”) that has his roots in programming and contributes stronger to code and systems in the backend.

Release your thoughts: publish as you go

I really like the attitude of some people regarding leveraging their work – for example, here: Mark Litwintschik reports on how he installed TensorFlow and executed a simple but instructional and funny “Hello World” model (based on Joel Grus’ hilarious post here). Mark’s article is easy to read, helpful, and sure to find its audience.

The origin of the term “Big Data”

Earlier this year, my colleague Kurt and I have written an article (in german language) that included a chapter on the origin of big amounts of data. In this article, we adopted the view that the term big data ultimately stemmed from the 3Vs (variety, velocity & volume) as attributes of the growing flood of data: the amount, the number of sources and the speed at which new data arrives is very large, i.e., “big”.
