Research Priorities for Robust and Beneficial Artificial Intelligence

Success in the quest for artificial intelligence has the potential to bring unprecedented benefits to humanity, and it is therefore worthwhile to investigate how to maximize these benefits while avoiding potential pitfalls. This article gives numerous examples (which should by no means be construed as an exhaustive list) of such worthwhile research aimed at ensuring that AI remains robust and beneficial.Comment: This article gives examples of the type of research advocated by the open letter for robust & beneficial AI at http://futureoflife.org/ai-open-lette

New quests for better attitudes

During the past few years considerable insight was gained into the QUEST algorithm both as a maximum likelihood estimator and as a Kalman filter/smoother for systems devoid of dynamical noise. The new algorithms and software are described and analytical comparisons are made with the more conventional attitude Kalman filter. It is also described how they may be accommodated to noisy dynamical systems

Short- and long-term effects of a multi-component physical activity intervention in primary school

There is compelling evidence that physical activity has numerous health benefits during childhood and adolescence. Insufficient levels of physical activity on the other hand can consequently affect cardiovascular and bone health, which may result in severe chronic diseases later in life. Cardiovascular disease and osteoporosis are two of the major chronic diseases affecting a large proportion of the adult population. Both diseases have their origins in childhood and it has been shown that for both, physical activity plays an important role in their prevention. The number of children not being sufficiently active has reached an alarming level and threatens to impose major health burdens worldwide. Thus, developing effective strategies to enhance children’s physical activity levels is of paramount interest for public health. School provides an optimal setting for physical activity promotion, since all children spend a large portion of their time there. This dissertation discusses a school-based randomized controlled trial aimed at increasing children’s physical activity levels and consequently their cardiovascular and bone health. The „Kinder- und Jugendsportstudie“ (KISS) is a school-based physical activity intervention lasting one school year. Of all primary school classes in the cantons of Aargau and Baselland comprising about 10% of the Swiss population, 28 first and fifth grade classes were randomly selected and allocated into an intervention (16 classes; n=297 children) and a control (12 classes, n=205 children) group. The mandatory and stringent multi-component intervention program consisted of daily physical education lessons, daily short activity breaks during academic lessons, and physical activity homework. Children in the control group had the compulsory three physical educations per week. The aim of this dissertation was to assess the effectiveness of KISS on cardiovascular risk and bone health and to explore whether the program was sufficiently effective in order to maintain health benefits over the following three years. In addition, this dissertation will provide a systematic update of existing school-based intervention studies aiming at increasing children’s physical activity and a quantification of physical education-related physical activity. There is strong evidence that school provides a promising setting for physical activity promotion. All school-based intervention studies done in recent years showed positive effects in at least one domain of physical activity. The most successful interventions had the design of a randomized controlled trial, were done over one school year using a multi-component approach integrated into the school curriculum, taught by physical education experts and involving family members. A common intervention strategy was to increase quantity and/or quality of physical education lessons. The particular role of physical education and its contribution to overall physical activity was the center of attention in the second publication of this dissertation. Even if children’s physical activity levels during physical education are relatively low, physical education contributes substantially to overall physical activity. Due to its nature of being a randomized controlled trial in children with a stringent physical activity program in and outside physical education over one school year and with the inclusion of physical education experts, KISS had excellent pre-conditions for being an effective program. Indeed, the results after nine month of intervention are promising. Compared to controls, children of the intervention group showed 14% reduced cardiovascular risk score, 5% reduced body mass index and skinfold thickness, 6% improved aerobic fitness, 18% higher physical activity levels, and 5-8% higher bone mineral content and bone mineral density. Three years after cessation of the program, intervention children still showed higher aerobic fitness and bone mineral content levels at weight-bearing sites of the skeleton compared to the control group. All other beneficial effects have disappeared. Even if short-term effects of the intervention are promising, the major key from a public health perspective is whether the effects of the prevention done during childhood will persist into late adolescence and adulthood. Although the maintained effects on aerobic fitness and bone health have considerable impact on public health, most of the beneficial health effects were not maintained three years after the intervention. This indicates that an intervention over one year is too short for maintained overall health effects. Thus, physical activity programs throughout the school years are needed. Our findings contribute to the growing body of evidence that school-based interventions can increase children’s health; however the major challenge now, is to find effective implementation strategies to transfer such programs into the real-world setting

Constructing Futures: Outlining a Transhumanist Vision of the Future and the Challenge to Christian Theology of its Proposed Uses of New and Future Developments in Technology

Transhumanists arc committed to re-evaluating the entire human condition and offering proposalsfor transcending mortality, principally by augmenting the human body with mechanical components or by transferring the human mind into intelligent hyper-computers. In this essay, the author\'s methodology is to critique the culture oftranshumanism, arguing, with Barbour, that all technology is tool whose use is determined by the cultural and socialframeworks within which it is utilized. Transhumanism is characterized as morally ambiguous, extremely individualistic, fixated upon health, vitality, and power, ideological, reductionist, and self-deluded. Its proposed use of technology is, thus, highly suspect and deserves a robust theological response

Magpie: towards a semantic web browser

Web browsing involves two tasks: finding the right web page and then making sense of its content. So far, research has focused on supporting the task of finding web resources through ‘standard’ information retrieval mechanisms, or semantics-enhanced search. Much less attention has been paid to the second problem. In this paper we describe Magpie, a tool which supports the interpretation of web pages. Magpie offers complementary knowledge sources, which a reader can call upon to quickly gain access to any background knowledge relevant to a web resource. Magpie automatically associates an ontologybased semantic layer to web resources, allowing relevant services to be invoked within a standard web browser. Hence, Magpie may be seen as a step towards a semantic web browser. The functionality of Magpie is illustrated using examples of how it has been integrated with our lab’s web resources

Lessons from a Restricted Turing Test

We report on the recent Loebner prize competition inspired by Turing's test of intelligent behavior. The presentation covers the structure of the competition and the outcome of its first instantiation in an actual event, and an analysis of the purpose, design, and appropriateness of such a competition. We argue that the competition has no clear purpose, that its design prevents any useful outcome, and that such a competition is inappropriate given the current level of technology. We then speculate as to suitable alternatives to the Loebner prize.Comment: 20 page
