SVM-based Transfer of Visual Knowledge Across Robotic Platforms

Barbara Caputo, Jie Luo

This paper presents an SVM--based algorithm for the transfer of knowledge across robot platforms aiming to perform the same task. Our method exploits efficiently the transferred knowledge while updating incrementally the internal representation as new inf ...

Negotiation of goal direction for cooperative transport

Roderich Gross

In this paper, we study the cooperative transport of a heavy object by a group of robots towards a goal. We investigate the case in which robots have partial and noisy knowledge of the goal direction and can not perceive the goal itself. The robots have to ...

Advancing knowledge and the knowledge economy

Dominique Foray

The revolution in information technology transforms not only information and its uses but, more important, knowledge and the ways we generate and manage it. Knowledge is now seen as input, output, and capital, even if imperfectly accounted for or understoo ...

Globalization of R&D: linking better the European economy to 'foreign' sources of knowledge and making EU a more attractive place for R&D investment

Dominique Foray

R&D internationalization is an important phenomenon. It involves the global allocation of a precious resource for national economies. The reason for this Report is that there is a strong feeling, based on partial evidence, that Europe is not taking part as ...

Constrained Tracking on a Road Network

Matthias Grossglauser

Many applications of wireless ad hoc sensor and actuator networks (WSANs) rely on the knowledge of node locations. These are challenging to obtain when nodes are mobile and are not equipped with any expensive positioning hardware. In this paper, we are int ...

Variable length coding over an unknown channel

Emre Telatar, Aslan Tchamkerten

Burnashev in 1976 gave an exact expression for the reliability function of a discrete memoryless channel (DMC) with noiseless feedback. A coding scheme that achieves this exponent needs, in general, to know the statistics of the channel. Suppose now that t ...

Adaptive cooperation between driver and assistant system to improve the road safety

Frédéric Holzmann

The last decades have seen the most important improvements of the safety on the road. But most of the accidents are still coming from the driver when a source of danger is not noticed or when the reaction is not correct during an unusual situation. Two way ...

Nonlinear modelling of double and triple period pitch breaks in vocal fold vibration

Auke Ijspeert, Jonas Buchli, Fritz Menzer

This paper reports a study on short-time subharmonic pitch breaks in vocal fold vibration, which are found to be a common feature of the human voice in spoken language. The observed pitch breaks correspond to a change in periodicity of the electrolaryngogr ...
