Neural Adaptive Admission Control Framework: SLA-driven action termination for real-time application service management
Get PDFAlthough most modern cloud-based enterprise systems, or operating systems, do not commonly allow configurable/automatic termination of processes, tasks or actions, it is common practice for systems administrators to manually terminate, or stop, tasks or actions at any level of the system. The paper investigates the potential of automatic adaptive control with action termination as a method for adapting the system to more appropriate conditions
in environments with established goals for both system’s
performance and economics. A machine-learning driven control
mechanism, employing neural networks, is derived and applied
within data-intensive systems. Control policies that have been
designed following this approach are evaluated under different
load patterns and service level requirements. The experimental
results demonstrate performance characteristics and benefits as well as implications of termination control when applied to different action types with distinct run-time characteristics. An automatic termination approach may be eminently suitable for systems with harsh execution time Service Level Agreements, or systems running under conditions of hard pressure on power supply or other constraints. The proposed control mechanisms can be combined with other available toolkits to support deployment of autonomous controllers in high-dimensional enterprise information systems
Active boulder falls in Terra Sirenum, Mars: constraints on timing and causes
No full textWe use time series images to identify significant active boulder falls in an impact crater on Mars. Evidence for active boulder falls include boulder trails with impact marks from bouncing and rolling, and dark patches from boulder impacts away from the base of the crater walls. We were able to define three time periods with active boulder falls and additional slope streak formation, for which we refined the most significant activity to a time period between January 2012 and March 2013. A search of 236 images within 500 km of the study site identified two further sites with similar, but reduced, activity during the same time period. We discuss plausible mechanisms for the boulder fall activity, and conclude that the local geology and crater age is likely to be of significant importance. Our method of identifying and highlighting such activity will allow further studies of active surface processes on Mars
Chaucer's borders
No full textWhilst Chaucer rarely used words like foreyn, alyen or enemi, the crossing of borders and the interrogation of identity are absolutely crucial to his poetics. The borderlands of identity – and in particular, crossings of borders, movements between identity – can be a helpful way of thinking about, and taking apart, received ideas of nation. We are now well used to thinking about and identifying transgression, the going beyond of a limit or border, in order to understand how power works in literary texts. Indeed, ‘border’ and ‘boundary’ did not have the same, rather definite, meanings they now have: a bordure was any edge; a bounde could mean any limitation on a piece of land, or simply the outer area of a space. Can we even think in terms of medieval borders when this was a world without formal borders? And does crossing a border always equate to transgression, a change of identity, or an encounter with the Other?
Book synopsis: Geoffrey Chaucer is widely acknowledged as the greatest English poet of the Middle Ages. His texts are studied extensively but, in order to be fully appreciated, they demand a nuanced understanding of the medieval period. This volume provides freshly illuminated access to Chaucer's writing through an unrivalled repertoire of contextual information and perspectives designed to enhance the independence and critical capacities of his modern readers. The featured essays are written not only by distinguished literary scholars but also by leading international historians. Geoffrey Chaucer in Context is an essential reference tool for anyone studying Chaucer and will help readers to identify his different voices and engage with the complexity and colour of his times with new awareness.
Illuminates context, rather than a simple provision of textual readings, in order to inform and enhance independent approaches to Chaucer
Contributions from leading international historians in addition to Middle English literature specialists ensure fresh and distinctive perspectives and information
Addresses all manner of questions - literary, historical, cultural, social, aesthetic, spiritual, political, economic, psychological, philosophical, scientific and linguistic - likely to be on the minds of anyone studying Chauce
Knowledge distillation: a survey
Get PDFIn recent years, deep neural networks have been successful in both industry and academia, especially for computer vision tasks. The great success of deep learning is mainly due to its scalability to encode large-scale data and to maneuver billions of model parameters. However, it is a challenge to deploy these cumbersome deep models on devices with limited resources, e.g., mobile phones and embedded devices, not only because of the high computational complexity but also the large storage requirements. To this end, a variety of model compression and acceleration techniques have been developed. As a representative type of model compression and acceleration, knowledge distillation effectively learns a small student model from a large teacher model. It has received rapid increasing attention from the community. This paper provides a comprehensive survey of knowledge distillation from the perspectives of knowledge categories, training schemes, teacher-student architecture, distillation algorithms, performance comparision and applications. Furthermore, challenges in knowledge distillation are briefly reviewed and comments on future research are discussed and forwarded

Visual search for facing and non-facing people: the effect of actor inversion
Get PDFIn recent years, there has been growing interest in how human observers perceive, attend to, and recall, social interactions viewed from third-person perspectives. One of the interesting findings to emerge from this new literature is the search advantage for facing dyads. When hidden amongst pairs of individuals facing in the same direction, pairs of individuals arranged front-to-front are found faster in visual search tasks than pairs of individuals arranged back-to-back. Interestingly, the search advantage for facing dyads appears to be sensitive to the orientation of the people depicted. While front-to-front target pairs are found faster than back-to-back targets when target and distractor pairings are shown upright, front-to-front and back-to-back targets are found equally quickly when pairings are shown upside-down. In the present study, we sought to better understand why the search advantage for facing dyads is sensitive to the orientation of the people depicted. To begin, we show that the orientation sensitivity of the search advantage is seen with dyads constructed from faces only, and from bodies with the head and face occluded. We replicate these effects using two different visual search paradigms. We go on to show that individual faces and bodies, viewed in profile, produce strong attentional cueing effects when shown upright, but not when presented upside-down. Together with recent evidence that arrows arranged front-to-front also produce the search advantage for facing dyads, these findings support the view that the search advantage is a by-product of the ability of constituent elements to direct observers' visuo-spatial attention
Achieving excellence in interpretative phenomenological analysis (IPA): four markers of high quality
Get PDFExisting guidance on evaluating the quality of Interpretative Phenomenological Analysis (IPA) research has provided criteria to assess work as good, acceptable or unacceptable. Given that IPA has become a well-established member of the qualitative methods repertoire, we think it is valuable now to focus in much more detail on the particular qualities that are the hallmark of high quality IPA research. Here we present four such qualities which are discussed in detail and illustrated through the use of exemplars from excellent IPA work. The qualities are: constructing a compelling, unfolding narrative; developing a vigorous experiential and/or existential account; close analytic reading of participants' words; attending to convergence and divergence. Finally, the four qualities are briefly considered in relation to the theoretical underpinnings of IPA
The Begum judgement on the couch
Get PDFThe article reviews the Supreme Court's decision on the Begum case from a psychoanalytic perspective; by lending our ear to the judgment with what Freud termed "evenly suspended attention", the analysis tries to excavate through the morass of legal niceties and subtleties surrounding the multiple grounds of appeal and cross-appeals through to its hidden core - the Secretary of State's decision to strip Shamina Begum of British citizenship. This core is not discussed, let alone decided upon by the Supreme Court, which resembles Freud's patient who 'practises the art of sheering off into intellectual discussion during their treatment, who speculate a great deal and often very wisely about their condition and in that way avoid doing anything to overcome it.
Autistic traits are associated with faster pace of aging: evidence from the Dunedin Study at age 45
Get PDFGrowing evidence indicates that the defining characteristics of Autism Spectrum Disorder (ASD) are distributed throughout the general population; hence, understanding correlates of aging in people with high autistic traits could shed light on ASD and aging. 915 members of the Dunedin longitudinal birth cohort completed a measure of autistic traits at age 45. A composite measure of the “pace of aging” was derived by tracking decline in 19 biomarkers across ages 26, 32, 38, and 45 years. Facial age was also assessed. Reports of perceived health were collected from participants themselves, informants, and interviewers. Higher self-reported autistic traits significantly correlated with a faster pace of aging, older facial age, and poorer self-, informant- and interviewer-rated health. After control for sex, SES and IQ, autistic traits were significantly associated with each variable: pace of aging (β=0.09), facial age (β=0.08), self- (β=-.15), informant (β=-.12), and interviewer-rated (β=-.17) health. Autistic traits measured at age 45 are associated with faster aging. Participants with high autistic traits appear to be more vulnerable to poor health outcomes, as previously reported for those clinically diagnosed with ASD. Therefore, autistic traits may have important health implications. Replicating these findings in samples of autistic people is needed to identify the mechanism of their effect on aging and physical health to improve outcomes for those with ASD diagnoses or high autistic traits
On the ethics of Naturalism: Sorley and Sidgwick on ethics and evolution
Get PDFThis paper addresses the question of the ethical significance of the theory of evolution in W. R. Sorley’s The Ethics of Naturalism (1st Edition 1885; 2nd Edition 1904). Sorley’s treatment is compared with that of his more influential contemporary, Henry Sidgwick, as well as with other works of the same period. The relevance of Sorley’s treatment for discussions of this topic in contemporary philosophy is explained. In addition, Sorley’s work is located within the historical and institutional context of its period
