Text Mining and Analytics

Written 2 years ago
I started with this course because I am interested in topic modeling. The first three weeks were the most useful for me, and were sufficient to give me a good start. The rest of the course was a bit more difficult to follow, mostly because the lecturer started giving highlights and skipped many details. This upped the pace, and I frequently had to pause the lectures to think about the contents. For me, it would have been preferable to replace weeks 4-6 with a more in-depth treatment of an extension to topic mining. Also, the lecturer's pronounciation is often a unclear, and I really needed the subtitles.

Having said that, I did learn a lot and am able to start trying topic modeling in practice.

Decision Making in a Complex and Uncertain World

Written a year ago
I took the course in November 2017 and enjoyed it a lot. The key concepts are explained well and gave me plenty of "food for thought". It is a nice mix of various disciplines.

Understanding the GDPR

Written a year ago
The course explains the basic concepts of the GDPR quite well. The lectures were well made, with good materials and in understandable English. This was not my first GDPR training, so I was aware of the basic concepts, but I still got some interesting insights and read some nice articles. If you're a GDPR novice, the course is a good starting point. If you know GDPR basic already, another course may be a better option.

Blockchain in the Energy Sector

Written 11 months ago
I'm afraid that I'm not a fan of this course. The blockchain introduction in week 1 is very shallow, and the following weeks are mostly interviews with some companies in the sector. Yes, they use blockchain, but it is a mystery why blockchain should be used instead of conventional technology. Each week took me less than an hour to complete, and I feel I would have learned a lot more watching videos on Youtube.

Having said that, the total time investment is not that large. So if you're considering this course, try it out, but don't expect the moon ;-)
