Computational models of primary visual cortex have demonstrated that principles of efficient coding and neuronal sparseness can explain the emergence of neurones with localised oriented receptive fields. Yet, existing models have failed to predict the diverse shapes of receptive fields that occur in nature. The existing models used a particular “soft” form of sparseness that limits average neuronal activity. Here we study models of efficient coding in a broader context by comparing soft and…

A Sparse Coding Model with Synaptically Local Plasticity and Spiking Neurons Can Account for the Diverse Shapes of V1 Simple Cell Receptive Fields

It is proved, mathematically, that sparseness and decorrelation are the key ingredients that allow for synaptically local plasticity rules to optimize a cooperative, linear generative image model formed by the neural representation.

Complex Sparse Code Priors Improve the Statistical Models of Neurons in Primate Primary Visual Cortex

It is found that models with complex sparse code prior are significantly better than models with classical Gabor and/or Laplacian of Gaussian filter priors for modeling and predicting the activities of neurons that have been earlier identified to exhibit higher-order (HO) complex pattern selectivity.

Inhibitory Interneurons Decorrelate Excitatory Cells to Drive Sparse Code Formation in a Spiking Model of V1

It is shown that adding a separate population of inhibitory neurons to a spiking model of V1 provides conformance to Dale's Law, proposes a computational role for at least one class of interneurons, and accounts for certain observed physiological properties in V1.

Role of Homeostasis in Learning Sparse Representations

By quantitatively assessing the efficiency of the neural representation during learning, a cooperative homeostasis mechanism is derived that optimally tunes the competition between neurons within the sparse coding algorithm.

Toward a Biologically Plausible Model of LGN-V1 Pathways Based on Efficient Coding

It is demonstrated that a two-layer model of the visual pathway from the lateral geniculate nucleus to V1 that incorporates these biological constraints on the neural circuits and is based on sparse coding can account for the emergence of experimental phenomena, diverse shapes of receptive fields and contrast invariance of orientation tuning of simple cells when the model is trained on natural images.

Sparse Coding Can Predict Primary Visual Cortex Receptive Field Changes Induced by Abnormal Visual Input

In every condition, the changes in receptive field properties previously observed experimentally were matched to a similar and highly faithful degree by all the models, suggesting that early sensory development can indeed be understood in terms of an impetus towards sparsity.

Constrained inference in sparse coding reproduces contextual effects and predicts laminar neural dynamics

An extended generative model for visual scenes that includes spatial dependencies among different features and provides a novel framework for contextual processing in the visual system proposing a well-defined functional role for horizontal axons and feedback projections is proposed.

Perceptual Decision Making “Through the Eyes” of a Large-Scale Neural Model of V1

It is shown that while both sparse and non-sparse linear decoding yield discrimination results quantitatively consistent with human psychophysics, sparse linear decoding is more efficient in terms of the number of selected informative dimension.

Learning modular representations from global sparse coding networks

It is suggested that sparse coding must be refined to incorporate stimulus-dependent plasticity, and as connections are strengthened amongst all the cells that become active in response to a given stimuli, the networks that emerge exhibit modularity and small-world topologies, both of which have been observed in networks in the cortex.

Sparse Coding Models Can Exhibit Decreasing Sparseness while Learning Sparse Codes for Natural Images

It is demonstrated that some sparse coding models, such as those employing homeostatic mechanisms on neural firing rates, can exhibit decreasing sparseness during learning, while still achieving good agreement with mature V1 receptive field shapes and a reasonably sparse mature network state.



Emergence of simple-cell receptive field properties by learning a sparse code for natural images

It is shown that a learning algorithm that attempts to find sparse linear codes for natural scenes will develop a complete family of localized, oriented, bandpass receptive fields, similar to those found in the primary visual cortex.

Spatial structure and symmetry of simple-cell receptive fields in macaque primary visual cortex.

Measurements of the spatial structure of simple-cell receptive fields in macaque primary visual cortex show a tendency for neurons that are well tuned in orientation and spatial frequency to have odd-symmetric receptive fields, and a population analysis reveals that the distribution of spatial profiles inPrimary visual cortex lies approximately on a one-parameter family of filter shapes.

Sparse coding in the primate cortex

There are now strong theoretical reasons and experimental evidence suggesting that the brain adopts a compromise between these extremes which is often referred to as sparse coding.

The Cost of Cortical Computation

Simple-Cell-Like Receptive Fields Maximize Temporal Coherence in Natural Video

It is shown that simple-cell-type receptive fields emerge when temporal response strength correlation is maximized for natural image sequences, and suggests an interpretation of simple cells in terms of invariant coding principles, which have previously been used to explain complex-cell receptive fields.

The two-dimensional spatial structure of simple receptive fields in cat striate cortex.

A reverse correlation method is developed that allows quantitative determination of visual receptive-field structure in two spatial dimensions and it is demonstrated that thereverse correlation method yields results with several desirable properties, including convergence and reproducibility independent of modest changes in stimulus parameters.
