Comparisons made in two studies of 21 methods for finding prototypes upon which to base the nearest prototype classifier are discussed. The criteria used to compare the methods are by whether they: (i) select or extract point prototypes; (ii) employ preor post-supervision; and (iii) specify the number of prototypes a priori, or obtain this number “automatically”. Numerical experiments with 5 da...

This work presents an application of diverse soft-computing techniques to the resolution of semaphoric regulation problems. First, clustering techniques are used to discover the prototypes which characterize the mobility patterns at an intersection. A prediction model is then constructed on the basis of the prototypes found. Fuzzy logic techniques are used to formally represent the prototypes i...

We used event-related fMRI to test whether recognition memory depends on visual similarity between familiar prototypes and novel exemplars. Subjects memorized portraits, landscapes, and abstract compositions by six painters with a unique style, and later performed a memory recognition task. The prototypes were presented with new exemplars that were either visually similar or dissimilar. Behavio...

A survey of different types of prototypes and current prototyping methods and tools is presented. Especially the usage of prototypes with use cases and scenarios is investigated, and an approach to requirements engineering combining the systematic use of prototyping and use cases is described. The approach consists of repeated prototype demonstration sessions with stakeholders in which use case...

A new dynamic strategy for Kohonen’s LVQ algorithms using growing and pruning methods is introduced. Once the learning system converges to a solution using a fixed number of prototypes, the growing method incrementally adds new prototypes in those local regions where the misclassification error is greater. The initial locations of the new prototypes are viewed as estimates of the new equilibriu...

Computers have become commonplace in our daily lives; they are embedded within so many products that they have largely become invisible. Furthermore, computers are used to aid in the design of those products and it is possible for the entire design process to be performed digitally. But humans are physical beings; evolved to have an innate understanding of the physical world. In contrast, this ...

One key factor in inexperienced users adopting mobile technology is the ease of use of mobile devices. The present paper investigates inexperienced user performance through a usability testing of three alternative prototypes of a mobile tablet application. For this purpose of the study, three prototypes have been investigated, built on the basis of previous research conducted in collaboration w...

2. Character Recognition System The paper is about the problem of finding good prototypes for a condensed nearest neighbor classifieiin a recognition system. A comparison study is done between two prototype representation schemes. The prototype search is done by a genetic algorithm which is able to generate novel prototypes (i.e. prototypes which are not among the training samples). I t is show...

Whereas rational and formal reasoning should be devoid of contradictions, people must often handle conflicting perspectives in everyday contexts. The present article is based on empirical studies of conflicting prototypes of forest in Sweden and Canada. Conflicting prototypes of forest correspond to different values and actions in real environments. The empirical data demonstrate how metaphoric...

The k-means is one of the most popular and widely used clustering algorithm, however, it is limited to only numeric data. The k-prototypes algorithm is one of the famous algorithms for dealing with both numeric and categorical data. However, there have been no studies to accelerate k-prototypes algorithm. In this paper, we propose a new fast k-prototypes algorithm that gives the same answer as ...
