In 1970 Masahiro Mori, a japanese robotics professor, described a phenomenon that the acceptance of a technically simulated, human-like entity (robots, avatars, etc.) does not increase steadily monotonically with the anthropomorphism (human-likeness) of this figure, but rather shows a sharp decline within a certain range. This was called the “Uncanny Valley”. It can be seen … Continue reading

What Happened to Aisoy Robotics?
In 2013 I bought a new robot called AISOY1 from Aisoy Robotics SL located in Spain which happens to be my home country. Here to the post in case you’re interested in getting more infos on the robot itself. I really enjoyed working with it but it was not running smoothly and as a student … Continue reading
A/B-Testing
Everyone interested in data science might have come across “A/B-Testing”. While many universities don’t seem cover this important subject, knowing that terminus is seen as basic knowledge during job interviews. I even found out that many co-workers seem to have an issue understanding how versatile this procedure can result to be. There is “no free … Continue reading

Long Time No See
It has been an extremely long time since my last blog post. I entered the professional world after finishing my master’s degree and I ended up as a data scientist and machine learning engineer. I’m covering both since I’m not a huge fan of tight specializations. I’m quite lucky that my working place allows you … Continue reading
Optimizing your Neural Nets
There are a lot of hyperparameter optimization tools such as SMAC. But I found it exhausting, even frustrating, to set it up for a neural network’s hyperparameter. I’ve found my favourite technique which whom I feel very confident with because I can have full insight into the procedure and make my own changes. In addition, … Continue reading
Dynamic Movement Primitives (DMPs) in a nutshell
As for my Bachelor thesis I have to learn the concept of DMPs, I thought it would be a great idea to write down a short summary. So what are DMPs? Dynamic Movement Primitives can be seen a mathematical formulation of movement primitives with autonomous non-linear differential equations. Their change of state during the passing … Continue reading
Long Distance Art
When I visited London last year I didn’t know I was going to see the world premiere of the very first robot acting as an artistic real-time assistant. It just happened by accident and I loved it! Sadly I haven’t had the time to write about it, that’s why I’m doing it now. ‘Long Distance … Continue reading
Handwritten Digit Recognition Using A Naive Bayes Classifier Trained With MNIST
‘The task consists of labeling the MNIST testing dataset’. That’s what we’ve been told at the Machine Learning lecture concerning the newest programming task. And it left us all petrified (kind of 😀 ). In groups of two we left the lecture and started with that interesting task. We decided to implement the handwritten digit recognition using … Continue reading

Introducing: Sparki
I really love Kickstarter. Not only you can support great, innovative projects but also get some cool stuff. ArcBotics’ Sparki was one of those awesome projects Kickstarter launched last year. After having read some very good reviews about their last project “Hexy the Hexapod” I decided to back their latest one and I don’t regret … Continue reading
Merry Christmas!!!
I wanted to do something special for Christmas. So the plan was to make an awesome robot holiday video with Keepon and Aisoy1 and send it to Robohub. But sadly my Aisoy1 had some problems, again, and I wasn’t able to code anything. I came to the conclusion that one should really reconsider buying an … Continue reading
