"A Random Walk on Eye Movements"

About the PhD school

  • Part 1: Computational modelling of natural viewing behavior: toward new analyses
  • Part 2: Anomalous perspectives beyond conventional statistical tools In this two-part seminar we discuss how by considering eye movements, and in particular the resulting sequence of gaze shifts, a stochastic process, a wide variety of tools become available for analyses and modelling beyond conventional statistical methods. In

Part 1 we give a brief, though critical, probabilistic tour of current computational models of eye movements and visual attention, and we lay down the basis for gaze shift pattern analysis. To this end, the concepts of Markov Processes, the Wiener process and related random walks within the Gaussian framework of the Central Limit Theorem will be introduced. In Part 2 we will deliberately violate fundamental assumptions of the Central Limit Theorem to elicit a larger perspective, rooted in statistical physics, for analysing and modelling eye movements in terms of anomalous, non-Gaussian, random walks and modern foraging theory.

About the speaker

Giuseppe Boccignone is an Associate Professor at the Department of Computer Science of the University of Milano, Italy, where he lectures on Principles and Models of Perception, Natural Interaction, Models for Affective Computing. He received the Laurea degree in theoretical physics from the University of Torino, Italy, in 1985. In 1986 he joined Olivetti Corporate Research, Ivrea, Italy, From 1990 to 1992, he served as a chief researcher of the Computer Vision Lab at CRIAI, Naples, Italy. From 1992 to 1994, he has held a Research Consultant position at Research Labs of Bull HN, Milano, Italy, leading projects on biomedical imaging and radiological information systems. From 1994 to 2008 he has been with the Dipartimento di Ingegneria dell'Informazione e Ingegneria Elettrica of the University of Salerno as an Assistant Professor and since 2002 as an Associate Professor. In 1998 he has been invited as a Visiting Researcher to the Center for Mapping Labs, at Ohio University and in 2000 as a Visiting Scientist at the Research Institute for Multimedia Systems, University of Alberta, Canada, working on information properties of images, in collaboration with Prof. Terry Caelli. In 2002 he was a Visiting Scientist at Prof. Larry Stark Labs, Department of Ophtalmology, University of Berkely, CA, and at the Institut fur Neuro-Bioinformatik, University of Luebeck, Germany involved in research related to eye movements and gaze-control. From 2002 to 2008 this research has been mainly carried on within the Natural Computation Lab (NCL, University of Salerno). From October 2008 to March 2012 he has been with the Dipartimento di Scienze dell’Informazione, University of Milano and then he has joined the new Dipartimento di Informatica (Dept. of Computer Science). Current research interests span the fields of computational vision, machine learning, affective computing, stochastic processes, epistemology of the artificial.
