An innovative task learning system called PLOW (Procedure Learning On the Web) lets end-users teach procedural tasks to automate their various web activities. Deep natural understanding and mixed-initiative interaction in PLOW makes the teaching process very natural and intuitive while producing efficient/workable procedures.

Providing domain knowledge needed by intelligent tutoring systems to teach a procedure to students is traditionally a difficult and time consuming task. This paper presents a system for making this process easier by allowing the automated tutor to acquire the knowledge it needs through a combination of programming by demonstration, autonomous experimentation, and direct instruction.

In this paper, we are interested inminimizing the sum of block sizes in a pairwise balanced design, where there are some constraints on the size of one block or the size of the largest block. For every positive integers n,m, wherem ≤ n, letS (n,m) be the smallest integer s for which there exists a PBD on n points whose largest block has sizem and the sum of its block sizes is equal to s. Also, ...

Removing suboptimal actions that can exist in a demonstration is s key problem to be solved in Robot Programming by Demonstration. In this paper we present the rst step of an approach for solving this problem. We present how the Con guration Space (Cspace) of a task can be derived from demonstration. A demonstration traces out paths on a number of Csurfaces in C-space. The idea is to use statis...

Programming by Demonstration: a Machine Learning Approach

It is now generally accepted that several types of “risks” can be recognized for built facilities and environments: they are not limited to collapses and heavy damages but involve comfort and way of life (cf. e.g. Augusti et al., 2003). The most rational way of tackling such risks and their reduction is Performance-based Design PBD (or, better, Performance-based Engineering). This lecture will ...

We develop a scalable cell-level analytical model for multi-cell infrastructure IEEE 802.11 WLANs under a so-called Pairwise Binary Dependence (PBD) condition. The PBD condition is a geometric property under which the relative locations of the nodes inside a cell do not matter and the network is free of hidden nodes. For the cases of saturated nodes and TCP-controlled long-file downloads, we pr...

Effective robot programming by demonstration requires the availability of multiple demonstrations to learn about all relevant aspects of the demonstrated skill or task. Typically, a human teacher must demonstrate several variants of the desired task to generate a sufficient amount of data to reliably learn it. Here a problem often arises that there is a large variability in the speed of executi...

Programming by demonstration (PBD) utilizes a human teacher to train a computer system to perform tasks within that system. This technique effectively improves productivity for many tasks, in many domains. Many tasks are repetitive in nature; these can be learned by PBD by recognizing the repetitions and generalizing these to iterative programs. We present a domain-independent approach to itera...
