Our goal is to make combinatorial problem-solving technology available to users who have no formal training in AI or OR. To achieve this aim, we have built a system, VICSS (Visual Constraint Specification System) that enables users to specify problems graphically. To simplify the specification process, VICSS relles heavily on progra~nming-by-demonstration (PBD) techniques. We believe, however, ...

This demonstration challenges the conventional art experience. It brings together the fields of art, science, and software integration. The goal was to create a new kind of painting based on embedded technology, experimenting with a new media: paintings augmented with RFIDs. The aim was to achieve interaction between the artist's paintings and art gallery visitors.

All-reflective optical systems are under consideration for future gravitational wave detector topologies. One approach in proposed designs is to use diffraction gratings as input couplers for Fabry-Perot cavities. We present an experimental demonstration of a fully suspended diffractively coupled cavity and investigate the use of conventional Pound-Drever-Hall length sensing and control techniq...

Malabsorption of prednisolone administered as enteric coated tablets was suspected following therapeutic failure in an asthmatic. This was investigated by cortisol estimation and a Synacthen test and substantiated by the demonstration of abnormally low absorption of prednisolone from these tablets which nevertheless were normally absorbed by a volunteer. The absorption of prednisolone from conv...

We report experimental demonstration of 8-PAM transmission using an 850 nm VCSEL and 100 m of OM4-type MMF. The 8-level driving signal was generated using a 3-bit DAC, the error rates were measured in real time using a conventional error analyzer. Maximum uncoded bit rate was 37.5 Gbps, which corresponds to 35.2 Gbps with 7% FEC overhead.

This paper discusses a discretisation scheme which is based on point collocation and integrated radial basis function networks (IRBFNs) for the solution of elliptic differential equations (DEs). The use of IRBFNs to represent the field variable in a given DE gives several advantages over the case of using conventional RBFNs and polynomials. Some numerical examples are included for demonstration...

Programming by demonstration requires detection and analysis of sequential patterns in a user’s input, and the synthesis of an appropriate structural model that can be used for prediction. This paper describes SEQUITUR, a scheme for inducing a structural description of a sequence from a single example. SEQUITUR integrates several different inference techniques: identification of lexical subsequ...

A goal of the Multi-tac project is to make combinatorial problem-solving technology available to users who have no formal training in AI or OR. To achieve this aim, we have built a system , ViCSS (Visual Constraint Speciication System) that enables users to specify problems graphically. To simplify the speciication process, ViCSS relies heavily on programming-by-demonstration techniques. We bel...

Programming by demonstration is an efficient way to acquire procedural knowledge, but it can require many examples to learn how to perform complex tasks. In this paper, we present a novel approach to using transfer learning in programming by demonstration. In particular, we describe a mechanism that learns how to transfer solutions to common subgoals from one task to another. We show that trans...

In this paper, we investigate the PBD-closure of sets K with {7, 13} ⊆ K ⊆ {7, 13, 19, 25, 31, 37, 43}. In particular, we show that v ≡ 1 mod 6, v ≥ 98689 implies v ∈ B({7, 13}). As a preliminary result, many new 13-GDDs of type 13q and resolvable BIBD with block size 6 or 12 are also constructed. Furthermore, we show some elements to be not essential in a Wilson bases for the PBD-closed set {v...
