Categorization and Typicality 1 Similarity-based Categorization and Fuzziness of Natural Categories Categorization and Typicality 2 Similarity-based Categorization and Fuzziness of Natural Categories
The adequacy of similarity to prototype as an account of categorization in natural concepts was assessed by analyzing the monotonicity of the relation between typicality of an item in a category and the probability of a positive categorization response using data from McCloskey & Glucksberg (1978). The analysis revealed a strong underlying similarity-based threshold curve, with systematic devia...

متن کاملThe Role of Similarity in Natural Categorization
The intuitive idea that those things that we put things into categories because we find them similar appears to be non-controversial, if not circular. Cars are clearly more similar to other cars than they are to trees, and trees more similar to other trees than they are to cars. However, a number of theorists have recently questioned the degree to which the notion of similarity is sufficiently ...
متن کاملFuzziness based sample categorization for classifier performance improvement
This paper investigates a relationship between the fuzziness of a classifier and the misclassification rate of the classifier on a group of samples. For a given trained classifier that outputs a membership vector, we demonstrate experimentally that samples with higher fuzziness outputted by the classifier mean a bigger risk of misclassification. We then propose a fuzziness category based divide...
متن کاملEffects of classification context on categorization in natural categories.
The patterns of classification of borderline instances of eight common taxonomic categories were examined under three different instructional conditions to test two predictions: first, that lack of a specified context contributes to vagueness in categorization, and second, that altering the purpose of classification can lead to greater or lesser dependence on similarity in classification. The i...
