Leibovitz (2012) Modelling visual processing via emergence (CSBBCS)Abstract: A model of low level visual processing is outlined along with a demonstration of the numerous phenomena it unifies. Specifically – filling in, visual memory, image stability, color homogeneity, blind spot, temporal edge detection, eye blink – phenomena that would ordinarily be investigated under different sub fields and with disparate models. The model is based on the interaction between recurrence and eye motion. The model is built using the Emergic Network system, which is a new cognitive modeling system created for this project and others like it. Emergic Networks facilitate the exploration of how recurrent and distributed functions produce functional emergent effects. I will present an overview of the Emergic Network System and the simulation results for each phenomena it models.

Leibovitz & West (2012) Cognitive Re-Use via Emergic Networks (ICCM Poster)Abstract: In this poster we introduce a new cognitive modeling system called Emergic Networks. The Emergic Network system is designed to facilitate functional, nonlinear decomposition with the aim of understanding how different neural systems can interact to produce specific instances of cognitive functionality. The first part of the paper briefly describes the motivation for the system and the second part briefly describes the system and provides a web location for downloading.

Lilac-ChaserAbstract: David Leibovitz will give a live demo of his research-in-progress and discuss the nature of his research and future plans. David will demonstrate a framework, whereby a Virtual Eye is looking at the Lilac Chaser visual illusion. Currently, the implementation has a minimal cognitive component, a set of photoreceptors for the fovea, and saccadic jitter for the eye.
