MURPHY consists of a camera looking at a robot arm, with a connectionist network architecture situated in between. By moving its arm through a small, representative sample of the 1 billion possible joint configurations, MURPHY learns the relationships, backwards and forwards, between the positions of its joints and the state of its visual field. MURPHY can use its internal model in the forward ...

own face, although children do not develop self-recognition before the age of about 18 months. Self-face recognition is clearly a high-level ability and might be an important component of self-awareness1. The question of how the brain responds to the sight of one’s own face has recently been tackled by Kircher and colleagues2. They used computerized morphing procedures to blend a photograph of ...

This paper considers three questions: (1) what is the role of financial markets in development, (2) why do some economies have such poorly developed financial markets, and (3) can government policy be used to promote financial market development? With respect to the first question, we formalize the widely-held notion that financial markets promote entrepreneurship, specialization, and learning-...

E-learning by doing is an important e-learning process, that provides several advantages but that requires a high interactivity degree, not always supported in e-learning contexts. In this paper, we propose to exploit a formal approach (based on Computational Logic) to define, verify and support the e-learning by doing paradigm. To this end, we introduce the SCIFF formal frameworks, its feature...

The solar photovoltaic (PV) industry in the United States has been the recipient of billions of dollars of subsidies at the federal and state level, often motivated by environmental externalities and dynamic spillovers from learning-by-doing in the installation of the technology. This paper investigates cost reductions due to learning-bydoing (LBD) using comprehensive data on all solar PV insta...

The relationship between population structure and violent conflict is complex and heavily dependent on the behavior of other variables like governance, economic prospects, and urbanization. While addressing rapid population growth might be a necessary condition for peace, it is by no means sufficient. Concomitant steps must also be taken to foster inclusivity, guarantee broader rights for all, ...

We present a series of models for doing statistical machine translation based on labeled semantic dependency graphs. We describe how these models were employed to augment an existing example-based MT system, and present results showing that doing so led to a significant improvement in translation quality as measured by the BLEU metric.

democray is the most importantn element in dewey’s thought. in this paper dewey’s theory on democray will be evaluated, furthermor some challenges are ascrbed to it: first, dewey has not presented any philosophical argument about his idea: “democracy is a moral ideal”. second: if it is known by a posteriori method that democracy is the best, this idea can not be generalized to future, so it cou...

Normally agents cooperate when they have a joint goal or are able to get a higher payoff by doing so. We present a new perspective, where an agent cooperates with another without an explicit intention. We study this perspective in the context of Art Games, by introducing a novel algorithm where a human agent cooperates with a video game system in generating music in an emergent fashion, without...
