On the number of categories for classification
Information Storage and Retrieval, 1969It is shown that under certain restrictions, n items should be classified into √n categories if the amount of information (in the Shannon sense) needed to retrieve them is to be a minimum.

Monoidal categories with natural numbers object
Studia Logica, 1989The authors begin by defining the concept of a left natural number object (LNNO) in a monoidal category. If it exists it is unique up to isomorphism. A right natural number object (RNNO) is defined in a similar way. If both exist then they are isomorphic. The authors also gives an example of an LNNO which is not RNNO.

A Generative Model for category text generation
Information Sciences, 2018The neural network model has been the fulcrum of the so-called AI revolution. Although very powerful for pattern-recognition tasks, however, the model has two main drawbacks: it tends to overfit when the training dataset is small, and it is unable to ...

Memory of Ordinal Number Categories in Macaque Monkeys
Journal of Cognitive Neuroscience, 2006AbstractWhat mechanism underlies serial order memory? Studying preverbal serial memory shows that macaque monkeys reproducing a sequence of items can acquire knowledge of item ordinal position. In our previous experiment, macaques were repeatedly presented with image lists (first shown sequentially and then simultaneously on a touch screen together ...

StarMap for Category-Agnostic Keypoint and Viewpoint Estimation
European Conference on Computer Vision, 2018Semantic keypoints provide concise abstractions for a variety of visual understanding tasks. Existing methods define semantic keypoints separately for each category with a fixed number of semantic labels in fixed indices.

Optimum number of Response categories
Current Psychology, 2021Through linear transformations of raw item scores, the paper converts 3-ponit, 4-point, 5-point and 7-point items to continuous, monotonic, normally distributed scores ranging between 1 to 5. This provides a platform for meaningful comparisons of scales with different number of response categories with respect to parameters like reliability, validity ...

About numbers as a semantic category
Behavioral and Brain Sciences, 2001Humphreys & Forde concentrate on the living/nonliving dissociation. However, further dissociations have been reported, including selective loss or preservation in recognizing body parts and numbers. This commentary outlines the relevance of the number category for understanding the organising principles of semantic memory.

Optimizing the number of search result categories
CHI '05 Extended Abstracts on Human Factors in Computing Systems, 2005Automatically generated web search result categories were found to be beneficial in our previous study. In that study, we used 15 result categories and left the optimal number of categories issue deliberately untouched. To address this matter, we conducted a new experiment with 27 participants to compare search user interfaces with 10, 20, and 40 ...

A classification method to reduce the number of categories in ART1
Systems and Computers in Japan, 2001AbstractThe ART (Adaptive Resonance Theory) neural network was proposed by Grossberg and colleagues to classify by certain criterion (vigilance parameter) a data set distributed across feature space. With ART1, the selection of existing categories and generation of new categories is performed appropriately using two procedures called competition and ...
