Definition
Hierarchical models for learning and memory make use of a network of modules for solving a cognitive task such as object recognition. The modules are constructed with multiple child nodes being connected hierarchically to a parent node. The modules at the lower levels process and represent simpler features of an object, while the modules at the higher levels represent more complex features. Hierarchical models of learning are generally considered to be more biologically inspired than other learning methods such as feed forward neural networks because of (1) the number of layers of the architecture and (2) their ability to process and integrate information from simple to complex, thereby implicitly learning the underlying characteristics of the data.
Theoretical Background
Understanding how the visual cortex learns to recognize objects is a critical issue in both Neuroscience and artificial intelligence. As humans...
