A common approach to content-based image retrieval is to use example images as queries; images in the collection that have low-level features similar to the query examples are returned in response to the query. In this paper, we explore the use of image regions as query examples. We compare the retrieval effectiveness of using whole images, single regions, and multiple regions as examples. We a...

Clinical examples are widely used as learning and testing sets for newly proposed artificial intelligence-based classifiers of signals and images in medicine. The results obtained from testing are usually taken as an estimate of the behavior of automatic recognition system in presence of unknown input in the future. This paper investigates and discusses the consequences of the non-uniform repre...

Revisions in the theoretical basis and practical applications of the Counting Method are described based on clinical and research experience with this technique, which aims to reduce intrusive traumatic memories. The importance of the role of imaginal exposure, rather than the therapeutic alliance, is emphasized, and the advantages of a more parsimonious, streamlined approach to exposure therap...

We analyze why and how erroneous examples can be beneficially employed in learning mathematics. The ‘Why’ addresses reasoning and attitudes that are rarely fostered in today’s mathematics lessons but which are useful for learning, certainly needed in real life and in all applications of mathematics as well as in maths itself. The ‘How’ addresses pedagogical strategies capitalizing on errors via...
