Hierarchical receptive field model
Webreceptive field, region in the sensory periphery within which stimuli can influence the electrical activity of sensory cells. The receptive field encompasses the sensory receptors that feed into sensory neurons and thus includes specific receptors on a neuron as well as collectives of receptors that are capable of activating a neuron via synaptic connections. … http://cbcl.mit.edu/publications/ps/nn99.pdf

Web16 de set. de 2010 · Simple cells in the primary visual cortex have segregated ON and OFF subregions in their receptive fields, while complex cells have overlapping ON and OFF subregions. ... The model that best reproduces our experimental results is a variation of the classical hierarchical model.
Web27 de out. de 2011 · Fig. 1 shows a diagram for this hierarchical receptive field model the steps for empirical Bayesian inference. Zero-mean Gaussian priors Following earlier work [11] , [36] , [43] , [44] , we will take the prior distribution to be a Gaussian centered at zero: (8) where is a covariance matrix that depends on hyperparameters in some yet-to-be … WebFirst, an input image is fed to the network. Filters of a given size scan the image and perform convolutions. The obtained features then go through an activation function. Then, the output goes through a succession of pooling and other convolution operations. As you can see, features are reduced in dimension as the network goes on.
