Abstract Recommender Systems (RSs) have played an important role in online retailing
portals and customers' decision-making processes. Recommender systems that are based …

Although the importance of unsupervised learning has been recognized since William
James's “blooming, buzzing confusion,” it has received less attention in the literature than …

Studies of supervised Categorization have demonstrated limited Categorization
performance in participants with autism spectrum disorders (ASD), however little research …

Despite the recent surge in research on unsupervised category learning, the majority of
studies have focused on unconstrained tasks in which no instructions are provided about the …

Studies focusing on unsupervised categorization and sorting behavior have traditionally
identified and empirically isolated a few select strategies frequently employed by observers …

Labels for the categories have been found to facilitate learning by boosting accuracy.
According to the label-feedback hypothesis, this facilitation is due to a mechanism …

Two experiments investigated what makes it more likely that pigeons' behavior will come
under the control of multiple relevant visual stimulus dimensions. Experiment 1 investigated …

From infancy, we recognize that labels denote category membership and help us to identify
the critical features that objects within a category share. Labels not only reflect how we …

Several researchers have reported that learning a particular categorization leads to
compatible changes in the similarity structure of the categorized stimuli. The purpose of this …

In the past two decades, human categorisation research has achieved significant progress
via the rigorous and systematic study of concepts in terms of category structures and their …
