This is the personal page of Dr.-Ing. Markus Weimer. I’m a Scientist at Yahoo! Labs based in Santa Clara, California. My research focusses on very large scale machine learning techniques and novel applications thereof.
Publications
A list of my publications can be found here.
Software I work(ed) on
- CofiRank: A collaborative filtering algorithm that supports predicting the ranking of items as opposed to mere rating.
- BMRM: Open source, modular and scalable convex solver for many machine learning problems cast in the form of regularized risk minimization problem.
- Elefant: A machine learning toolbox. My contributions include a bridge that renders UIMA annotators into feature extraction tools for machine learning. This code is Open Source under the Mozilla Public License.
- DkPro: A set of UIMA annotators. Only available under a restrictive licence.

Former affiliations
- I obtained my PhD as a student in the graduate school for the improvement of e-learning at the computer science department of the Technische Universität Darmstadt, Germany. I worked on applications of machine learning in elearning. To do so, I was lucky enough to gather support by two supervisors: Max Mühlhäuser (TUD) and Alex Smola (Yahoo! Research / Australian National University).
- Yahoo! Research: Research intern. I worked on email spam filters in the SPARTA project.
- Statistical Machine Learning Program of NICTA: Visiting Scholar
- Data Mining Group MINE of Fraunhofer’s Integrated Publication and Information Systems Institute (IPSI): Research associate
- Centre for Complex Systems and Control (CDSC) at The University of Newcastle, Australia: Visiting Scholar
