Interests & projects

  • Within artificial intelligence, my focus is on perceptual intelligence and (lifelong) machine learning
  • Monk is our continuous project for allowing access to large and diverse historical archives which are difficult to access by means of traditional 'OCR' approaches due to their special fonts or handwritten style. Since 2009, Monk provides a means of continuously training handwriting recognizers that create indices of handwritten collections. Monk was one of the demonstrators in the EU/SNN Target project
  • May 2019: EU/ITN Manic project approved, participation: ML and neuromorphic computing / cognitive materials
  • 2018 EU/ITN Perico project participation: Machine learning for peroxisome classification
  • Dead Sea Scrolls ERC project with Mladen Popovic (PI) and Hans van der Plicht (14C dating)


  • 2020-09-08 - PhD position for AI student with physics interest (due to EU regulations this position is not intended for UG students, sorry. Candidates need to have received their training in AI elsewhere). The scientific aim of MANIC is to synthesize materials that can function as networks of neurons and synapses by integrating conductivity, plasticity and self-organization.

  • 2020-03-03 - AI colloqium From Boston to Eden - or how to get systems that are really autonomous and sufficiently intelligent to survive in their niche. In this presentation I argue that reinforcement learning methods currently are still very much handcrafted. Only an optimal reward structure and schedule yields success, which requires often more than an single PhD project. On the other hand, the human and animal brain do not have the helping hand of an ever-present external engineer setting up the framework for survival. Modern AI should take a better look at what is known about the old brain, which provides a general but quick valuation of the current state of the world. This would allow for a really autonomous reinforcement learning which does not require the development of painstakingly handcrafted reward structures, neural-network hyper-parameter values and specifically optimized training schedules.
