Programming by Demonstration has proved to be an interesting research area. Nevertheless, despite many experimental systems, it did not find any field area where it should be used extensively. In this paper, we describe a Computer Aided mechanical Design system which incorporates Programming by Demonstration capabilities, named EBP, for Example-Based Programming in Parametrics. EBP is intended ...

Programming by demonstration seeks to allow people to communicate algorithms easily to computers. The world in which the communication takes place, and the set of actions that can be performed in that world, both influence the efficiency and correctness of the transmitted algorithms, and the extent to which efficiency and correctness can be guaranteed. This paper discusses the effects of differ...

Pseudonym systems allow users to interact with multiple organizations anonymously by using pseudonyms. Such schemes are of significant practical relevance because it is the best means of providing privacy for users. In previous works, users transact with a organization by demonstration of possession of a credential issued by the organization or relationship with another credential. However, the...

As performance assessment in medicine moves into a competence-based era there is a need to develop procedure-specific tools for evaluating technical ability. Spinal anaesthesia is one of the fundamental skills of the practicing anaesthetist. Changes in learning opportunities for trainees over the last decade mandates a change in the way practical skills are taught and assessed. In order to opti...

An educational program, consisting in a clear explanation of the technical aspects and use of the adrenaline auto-injection devices (AAD) and in a practical test utilizing a demonstration kit was given to 350 patients from our outpatient clinic. AAD was also distributed to 50 patients formerly followed by another allergy clinic without training. At practical control test, only 10% of the untrai...

Ontology, an explicit specification of shared conceptualization, has been increasingly used to define formal data semantics and improve data reusability and interoperability in enterprise information systems. In this paper, we present and demonstrate SOR (Scalable Ontology Repository), a practical system for ontology storage, reasoning, and search. SOR uses Relational DBMS to store ontologies, ...

In this paper, we present a practical place and object recognition method for guiding visitors in building environments. Due to motion blur or camera noise, places or objects can be ambiguous. The first key contribution of this work is the modeling of bidirectional interaction between places and objects for simultaneous reinforcement. The second key contribution is the unification of visual con...

We describe theoretical bounds and a practical algorithm for teaching a model by demonstration in a sequential decision making environment. Unlike previous efforts that have optimized learners that watch a teacher demonstrate a static policy, we focus on the teacher as a decision maker who can dynamically choose different policies to teach different parts of the environment. We develop several ...

In this paper, texture analysis based on wavelet transformations is elaborated. The paper is meant as a practical guideline through some aspects of a wavelet-based texture analysis task. The following aspects of the problem are discussed: discrete and continuous wavelet decompositions, texture features for grey-level textures, extensions to colour texture and rotation-invariant features, and cl...

This paper introduces the concept of metaphorical structurer as a way of conciliating user interface development by demonstration and by generation so that advantages of both approaches are exploited together. It basically consists of substituting part or whole of the contents of a preliminary presentation model by a set of pre-defined specifications attached to a presentation and behavior. Thi...
