I-POMDP: An infomax model of eye movement
- In Proceedings of the International Conference on Development and Learning
, 2008
"... Abstract—Modeling eye-movements during search is important for building intelligent robotic vision systems, and for understanding how humans select relevant information and structure behavior in real time. Previous models of visual search (VS) rely on the idea of “saliency maps ” which indicate like ..."

likely locations for targets of interest. In these models the eyes move to locations with maximum saliency. This approach has several drawbacks: (1) It assumes that oculomotor control is a greedy process, i.e., every eye movement is planned as if no further eye movements would be possible after it. (2
Movellan, “Infomax control of eye movements
- IEEE Trans. Autonom. Mental Develop
, 2010
"... Abstract—Recently, infomax methods of optimal control have begun to reshape how we think about active information gathering. We show how such methods can be used to formulate the problem of choosing where to look. We show how an optimal eye movement controller can be learned from subjective experien ..."

An infomax controller for real time detection of social contingency
- in Proceedings of 2005 4th IEEE International Conference on Development and Learning
, 2005
"... Abstract — We present a model of behavior according to which organisms react to the environment in a manner that maximizes the information gained about events of interest. We call the approach “Infomax control ” for it combines the theory of optimal control with information maximization models of pe ..."

Regularization in Oculomotor Control
- In Proceedings of the European Symposium on Artificial Neural Networks
, 2000
"... In modelling the development of the oculomotor control system using neural networks, it is important to determine the appropriate cost function on which to train the models. Whilst blur and disparity are fairly obvious error components, choosing the regularization component is less easy. In this pap ..."

A Barebones Communicative Robot Based on Social Contingency and Infomax Control
"... Abstract-In this paper, we present a barebones robot which is capable of interacting with humans based on social contingency. It expands the previous work of a contingency detector into having both human-model updating (developmental capability) and policy improvement (learning capability) based on ..."

Research Article Infomax Algorithm for Filtering Airwaves in the Field of Seabed Logging
, 2014
"... Abstract: This research focuses on applying Independent Component Analysis (ICA) in the field of Seabed Logging (SBL). ICA is a statistical method for transforming an observed multidimensional or multivariate dataset into its constituent components (sources) that are statistically as independent fr ..."

Linear Network Models of the Oculomotor Integrators
, 1995
"... The oculomotor system uses integrators to transform velocity signals to control eye position. We model such an integrator as a linear network with a marginal mode separated from stable modes by a large spectral gap. The model neurons carry a superposition of position and velocity signals, just as ob ..."

Is an Internal Model of Head Orientation Necessary for Oculomotor Control?
"... ABSTRACT: In order to test whether the control of eye movement in response to head movement requires an internal model of head orientation or instead can rely on directly sensing information about head orientation and movement, perceived gravity was separated from physical gravity to see which domin ..."

Analog VLSI-based Modeling of the Primate Oculomotor System

Analog Very Large Scale Integrated (VLSI) electronic circuit technology provides such an enabling technology. We here describe a neuromorphic syst ..."
