I left the world of research years ago. I mean years ago.
This page mostly chronicles old work from my previous life as an academician. Most of the links here need to be fixed; you can find some that are more likely to work over at http://research.google.com/pubs/DavidCohn.html.
- Learning structure from document bases – the vast majority of available electronic documents reside in unstructured document bases. Hypertext remains woefully inadequate: it is labor-intensive, static, one-directional, and limited to the perspective of the hypertext author. And when we move beyond the traditional text document to audio, video, and other forms of recorded information, even the rudimentary benefits of hypertext are missing.
- Can we automate the extraction of relationships between documents to generate a dynamic structure that lets users navigate and manipulate unstructured document bases at the conceptual level?
- Active learning – many learning problems in pattern recognition and information retrieval afford chances for the learner to select or influence the training data it receives. How should it select training data to learn most quickly, for the least cost?
- Also dabbled in: thin-client robotics, decision support and optimization.
