Programming by demonstration systems acquire procedural knowledge from examples, and then use that knowledge to execute the learned procedure on new instances. We present an architecture, called version space algebra, for learning this type of procedural knowledge, and describe an implemented system for programming by demonstration in the text-editing domain. We present results showing the syst...

It has been shown that for k = 8 or 9, there exists a BIBD(v, k, 1) for all positive integers v == 1 or k (mod k(k-1)), with some possible exceptions. We show that such designs exist for 49 of these exceptional values. A balanced incomplete block design (BIBD) with parameters (v, k, 1) is a pair (X, A) where X is a v-set and A is a family of k-subsets (where 2 < k < v) called blocks, such that ...

OBJECTIVE To offer a practical demonstration of regression models recommended for count outcomes using longitudinal predictors of children's medically attended injuries. METHOD Participants included 708 children from the NICHD child care study. Measures of temperament, attention, parent-child relationship, and safety of physical environment were used to predict medically attended injuries. ...

One of the most natural ways to acquire procedural knowledge is to watch somebody performing a number of actions and try to abstract this observed action sequence in order to make it applicable to a wider range of situations. This abstraction process can be significantly facilitated if the performing agent gives additional hints e.g. on the reasons for choosing a particular action or dealing wi...

For every v ≡ 5 (mod 6) there exists a pairwise balanced design (PBD) of order v with exactly one block of size 5 and the rest of size 3. We will refer to such a PBD as a PBD(5∗, 3). A flower in a PBD(5∗, 3) is the set of all blocks containing a given point. If (S,B) is a PBD(5∗, 3) and F is a flower, we will write F ∗ to indicate that F contains the block of size 5. The flower intersection pro...

Shape matching is a popular method for simulating deformable objects in real time as it is fast and stable at large time steps. Although shape matching can simulate large elastic deformation and ductile fracturing, until now, they are limited to scenarios with relatively small plastic deformation. In this work, we present a method for simulating deformable solids undergoing large plastic deform...

This Paper presents improvements done to a Programming by Demonstration(PbD)system in order to handle complex one and two hand manipulations. In order to do this, functional roles were added to the systems knowledge base. According to them a probability density function expressing the relationship between the manipulated objects has been set up. Since one object can fulfill several functional r...

In demonstration, speakers use real-world activity both for its practical effects and to help make their points. The demonstrations of origami mathematics, for example, reconfigure pieces of paper by folding, while simultaneously allowing their author to signal geometric inferences. Demonstration challenges us to explain how practical actions can get such precise significance and how this meani...

We present a visual language that serves as a novel form of feedback in a Programming by Demonstration (PBD) interface. The language explicitly represents data, such as les, with unique icons and implicitly represents operations by changes to data icons, so that operations reeect the changes seen in the interface when executed. In addition, the language is used to provide feedback to the user b...

In 2008, the Ontario Long Term Care Association was awarded funding from HealthForceOntario to assist with its nursing recruitment strategy based on research it had initiated in 2007. The research goal was to understand the career motivations and perceptions of students enrolled in registered nursing (RN) and registered practical nursing (RPN) programs in Ontario to develop and test a message t...
