Uncertain Reasoning and Learning for Feature Grouping

ZuWhan Kim, Ramakant Nevatia
1999 Computer Vision and Image Understanding  
Hierarchical perceptual organization is needed for 3-D object detection and description. The hypothesize and verify paradigm offers one approach to this task.  ...  Hypotheses are generated from simpler features satisfying some possibly task dependent properties. More global evidence is used to verify and assign a confidence measure to the hypotheses.  ...  The main reason for not using these hypotheses in learning is that the evidence for them can be highly variable.  ...

Feature-based versus category-based induction with uncertain categories

Oren Griffiths, Brett K. Hayes, Ben R. Newell
2012 Journal of Experimental Psychology. Learning, Memory and Cognition  
Previous research has suggested that when feature inferences have to be made about an instance whose category membership is uncertain, feature-based inductive reasoning is used to the exclusion of categorybased  ...  The present experiments examined the conditions that drive feature-based and category-based strategies in induction under category uncertainty.  ...  Decision-Only Tasks: Implications for Category Learning and Exemplar Availability Another characteristic feature of uncertain induction tasks, as opposed to induction tasks in which categorization is certain  ...

Induction with uncertain categories: When do people consider the category alternatives?

Brett K. Hayes, Ben R. Newell
2009 Memory & Cognition  
However, the prevalence of such single-category reasoning was greatly reduced by highlighting the costs of neglecting nontarget alternatives and by asking for inferences before categorization decisions  ...  Participants were shown two categories and a novel exemplar with a feature that indicated that the exemplar was more likely to belong to one category (target) than to the other (nontarget).  ...  The two groups of planets are called Class E and Class K. To help you learn each class we will describe some of the characteristics of eight Class E planets and eight Class K planets.  ...
