PET evidence for multiple strategies of categorization.

It is widely held that people use multiple strategies to categorize their experiences in the world. We conducted a pair of neuroimaging experiments to identify the neural correlates of two of these strategies--rule application and exemplar similarity. Participants were instructed to perform either a rule- or an exemplar-based categorization task while changes in cerebral blood flow were measure...

Thesis: Multiple Kernel Learning for Object Categorization

Object Categorization is a challenging problem, especially when the images have clutter background, occlusions or different lighting conditions. In the past, many descriptors have been proposed which aid object categorization even in such adverse conditions. Each descriptor has its own merits and de-merits. Some descriptors are invariant to transformations while the others are more discriminati...

Visual Object Categorization using Topic Models

This project investigates the applicability of image annotation algorithms based on Latent Dirichlet Allocation (LDA) to a task different from the one for which they were originally designed: visual object categorization. We developed a topic model which is based on an existing approach and evaluated its performance on four datasets which we created from the PASCAL database using different feat...

Object Categorization by Compositional Graphical Models

This contribution proposes a compositionality architecture for visual object categorization, i.e., learning and recognizing multiple visual object classes in unsegmented, cluttered real-world scenes. We propose a sparse image representation based on localized feature histograms of salient regions. Category specific information is then aggregated by using relations from perceptual organization t...

Alternative strategies of categorization.

Psychological studies of categorization often assume that all concepts are of the same general kind, and are operated on by the same kind of categorization process. In this paper, we argue against this unitary view, and for the existence of qualitatively different categorization processes. In particular, we focus on the distinction between categorizing an item by: (a) applying a category-defini...
