Robust Computer Algebra, Theorem Proving, and Oracle AI
In the context of superintelligent AI systems, the term "oracle" has two
meanings. One refers to modular systems queried for domain-specific tasks.
Another usage, referring to a class of systems which may be useful for
addressing the value alignment and AI control problems, is a superintelligent
AI system that only answers questions. The aim of this manuscript is to survey
contemporary research problems related to oracles which align with long-term
research goals of AI safety. We examine existing question answering systems and
argue that their high degree of architectural heterogeneity makes them poor
candidates for rigorous analysis as oracles. On the other hand, we identify
computer algebra systems (CASs) as being primitive examples of domain-specific
oracles for mathematics and argue that efforts to integrate computer algebra
systems with theorem provers, systems which have largely been developed
independent of one another, provide a concrete set of problems related to the
notion of provable safety that has emerged in the AI safety community. We
review approaches to interfacing CASs with theorem provers, describe
well-defined architectural deficiencies that have been identified with CASs,
and suggest possible lines of research and practical software projects for
scientists interested in AI safety.Comment: 15 pages, 3 figure
Anion–arene adducts: C–H hydrogen bonding, anion– interaction, and carbon bonding motifs
This article summarizes experimental and theoretical evidence for the existence of four distinct binding modes for complexes of anions with charge-neutral arenes. These include C–H hydrogen bonding and three motifs involving the arene– system—the noncovalent anion– interaction, weakly covalent interaction, and strongly covalent interaction
Eating disorders in the time of COVID-19.
We have all been stunned by the speed of this viral pandemic. At the time of writing, one fifth of the world is under lockdown. The main foci have been on the public health effort to contain the spread of the virus, and the care of individuals with acute infection. We, in eating disorders, must have a broader brief. Not only must we help care for those sufferers who contract COVID-19, we must also address the impact-psychological, financial and social - on those that do not. The peculiarities of COVID-19 and the reaction of the public and governments to it, have particular relevance for people living with an eating disorder and those who care for them
AI Safety and Reproducibility: Establishing Robust Foundations for the Neuropsychology of Human Values
We propose the creation of a systematic effort to identify and replicate key
findings in neuropsychology and allied fields related to understanding human
values. Our aim is to ensure that research underpinning the value alignment
problem of artificial intelligence has been sufficiently validated to play a
role in the design of AI systems.Comment: 5 page
Integrative Biological Simulation, Neuropsychology, and AI Safety
We describe a biologically-inspired research agenda with parallel tracks
aimed at AI and AI safety. The bottom-up component consists of building a
sequence of biophysically realistic simulations of simple organisms such as the
nematode , the fruit fly ,
and the zebrafish to serve as platforms for research into AI
algorithms and system architectures. The top-down component consists of an
approach to value alignment that grounds AI goal structures in neuropsychology,
broadly considered. Our belief is that parallel pursuit of these tracks will
inform the development of value-aligned AI systems that have been inspired by
embodied organisms with sensorimotor integration. An important set of side
benefits is that the research trajectories we describe here are grounded in
long-standing intellectual traditions within existing research communities and
funding structures. In addition, these research programs overlap with
significant contemporary themes in the biological and psychological sciences
such as data/model integration and reproducibility.Comment: 5 page
Orthorexia nervosa and self-attitudinal aspects of body image in female and male university students.
The present study was designed to investigate orthorexia nervosa, or the phenomenon of being preoccupied with consuming healthy food. Specific aims were to explore relationships between orthorexia features and attitudes towards body image, fitness and health in normal weight female and male university students with high levels of healthy food preoccupation, i.e. orthorexia nervosa.
METHODS Participants were 327 female (N = 283) and male (N = 44) students aged 18 to 25 years. All participants completed the Polish adaptation of the 15-item questionnaire assessing orthorexia eating behaviours (the ORTHO-15) and the Multidimensional Body-Self Relations Questionnaire (the MBSRQ). Relationships between scores on the ORTHO-15 and MBSRQ were explored in the 213 students who had high levels of preoccupation with a healthy food intake (68.55% women and 43.18% men, respectively).
RESULTS: There were no statistically significant differences in the levels of orthorexia behaviours between females and males. In female students with orthorexia nervosa, preoccupation with consuming healthy food was significantly correlated with the MBSRQ subscale scores for overweight preoccupation, appearance orientation, fitness orientation, health orientation, body areas satisfaction and appearance evaluation. Conversely, in male students with orthorexia nervosa there were no correlations between orthorexic behaviours and the MBSRQ subscales. In female students with orthorexia nervosa multivariable linear regression analysis found high body areas (parts) satisfaction, low fitness orientation, low overweight preoccupation and low appearance orientation were independent predictors of greater fixation on eating healthy food. In male students, we found that aspects of body image were not associated with preoccupation with healthy eating.
CONCLUSION: A strong preoccupation with healthy and proper food was not associated with an unhealthy body-self relationship among Polish female student with orthorexia nervosa
