The Role Of Prototype Learning In Hierarchical Models Of Vision, Michael David Thomure
The Role Of Prototype Learning In Hierarchical Models Of Vision, Michael David Thomure
Dissertations and Theses
I conduct a study of learning in HMAX-like models, which are hierarchical models of visual processing in biological vision systems. Such models compute a new representation for an image based on the similarity of image sub-parts to a number of specific patterns, called prototypes. Despite being a central piece of the overall model, the issue of choosing the best prototypes for a given task is still an open problem. I study this problem, and consider the best way to increase task performance while decreasing the computational costs of the model. This work broadens our understanding of HMAX and related hierarchical …
