Hi! I am Jan, a Ph.D. student at the Ubiquitous Knowledge Processing (UKP) Lab, Technical University of Darmstadt, Germany. My research focuses on data annotation, especially improving annotation efficiency for NLP. As part of the INCEpTION project, we build a batteries-included platform for text annotation. I also am an experienced software engineer, especially in backend development as well as a system architect and administrator. In my free time, I love to learn Mandarin.
In addition to my current research, I am also available as an AI consultant. I have a strong background in data annotation including best practices, increasing annotation efficiency and quality, software backend engineering as well as building AI IT infrastructure. If that sounds interesting, then I would be happy hearing from you!
PhD in Computer Science, 2018 - now
MSc in Computer Science, 2017
BSc in Computer Science, 2014
After finishing Probability and Statistics by Stanford Online, I wanted to improve my knowledge of statistics further. The logical choice was to take Probability - The Science of Uncertainty and Data MITx (6.
For seqviz and INCEpTION external recommender, I recently had the problems that I needed to use BERT for sequence tagging but needed to predict labels for my own tokens. The problem is that transformers typically use subword tokenization like WordPiece or Sentence piece.
I recently got interested in economics and finance. A post on Hacker News was recommending to take Economics of Money and Banking on Coursera as an introduction. I really enjoyed the course and will give a brief review of it here.
In order to brush up my math skills, I started the Probability and Statistics by Stanford Online. I found it via the Free online machine learning curriculum by Chip Hyuen. If you do not know her, make sure to read her blog and books!
Introduction In October, I participated together with a friend in the 2019 International Collegiate Competition for Brain-inspired Computing organized by Tsinghua University. The task was to develop an AI system
