70 results about "Normalization model" patented technology

The normalization model is an influential model of responses of neurons in primary visual cortex. David Heeger developed the model in the early 1990s, and later refined it together with Matteo Carandini and J. Anthony Movshon. The model involves a divisive stage. In the numerator is the output of the classical receptive field. In the denominator, a constant plus a measure of local stimulus contrast. Although the normalization model was initially developed to explain responses in the primary visual cortex, normalization is now thought to operate throughout the visual system, and in many other sensory modalities and brain regions, including the representation of odors, the modulatory effects of visual attention, the encoding of value, and the integration of multisensory information. Its presence in such a diversity of neural systems in multiple species, from invertebrates to mammals, suggests that normalization serves as a canonical neural computation.

Method and system for generating a normalized configuration model

Normalized data models are programmatically generated from a combination of product configuration model data, product configuration engine runtime validation, normalized data mappings, and settings files declaring the scope of model content. A master model generation process effectively transforms conventional configuration data into normalized configuration data. The normalized configuration data allows a user to, for example, conduct comparative product configurations. In one embodiment, a normalized model generation process generates normalized data model representing attributes and normalized features of a product. In one embodiment, the normalized configuration data model is then added to in-memory data structures used during runtime contextual configuration analysis, thus reducing the total number of data items preserved as efficiencies result from eliminating duplication and effective use of search structures. In-memory representation of the normalized configuration data model can then be serialized to disk as a file to be loaded for runtime use in a deployment.
