Information-Driven Organization of Visual Receptive Fields
By using information theory to reduce the state space of sensor arrays, such as receptive fields, for AI decision making we offer an adaptive algorithm without classical biases of hand coded approaches. This paper presents a way to build an acyclic directed graph to organise the sensor inputs of a visual receptive field. The Information Distance Metric is used to repeatedly select two sensors, ...
متن کاملHierarchical self-organization of minicolumnar receptive fields
We study self-organization of receptive fields (RFs) of cortical minicolumns. Input driven self-organization is induced by Hebbian synaptic plasticity of afferent fibers to model minicolumns based on spiking neurons and background oscillations. If input in the form of spike patterns is presented during learning, the RFs of minicolumns hierarchically specialize to increasingly small groups of si...
متن کاملNormative theory of visual receptive fields
This article gives an overview of a normative computational theory of visual receptive fields, by which idealized shapes of early spatial, spatio-chromatic and spatiotemporal receptive fields can be derived in an axiomatic way based on structural properties of the environment in combination with assumptions about the internal structure of a vision system to guarantee consistent handling of imag...
متن کاملThe important aspects of visual encoding: relating receptive fields to mutual information rates in visual neurons
In studying how visual neurons encode stimuli, there is currently a large divide between information theoretic approaches and more traditional receptive field-based analyses. While receptive fields (RFs) are straightforward to measure and are a standard part of almost every visual physiology experiment, traditional RF-based models of neurons are unable to explain the timing precision and the re...
متن کاملOrganization of suppression in receptive fields of neurons in cat visual cortex.
1. The response to an optimally oriented stimulus of both simple and complex cells in the cat's striate visual cortex (area 17) can be suppressed by the superposition of an orthogonally oriented drifting grating. This effect is referred to as cross-orientation suppression. We have examined the spatial organization and tuning characteristics of this suppressive effect with the use of extracellul...
