Hans Peter Graf is head of the machine learning research department at NEC Laboratories America in Princeton. The department develops machine learning algorithms, as well as a range of applications in semantic text analysis, cognitive video interpretation and bio-medical analysis. His responsibilities include technology transfer to business units and the commercialization of research results. An example is the recently released e-Pathologist, a system assisting pathologists with the interpretation of histological samples, which contains key algorithms developed by the department.
