Multi-View Relationships for Analytics and Inference

Subjects: subject: 170203 Knowledge Representation and Machine Learning
subject: FOS: Psychology

description: An interesting area of machine learning is methods for multi-view data, relational data whose features have been partitioned. Multi-view learning exploits relationships between views, giving it certain advantages over traditional single-view techniques, which may struggle to fi nd these
relationships or only learn them implicitly. These relationships are often especially salient in understanding the data or performing prediction. This work explores an underutilized approach in multi-view learning: to focus on multi-view relationships|the latent variables that govern
relations between views|themselves as units of analysis. We investigate how this approach impacts analytics and inference in ways that standard multi-view and single-view learning cannot. We hypothesize that by ignoring relations between views or factoring them in only indirectly,
standard approaches risk overlooking key structure. Accordingly, our goal is to investigate the extent multi-view relationships can be characterized and employed as units of analysis in descriptive analytics and inference. We present novel methods to do so, either using domain knowledge or by learning from data, which reveal structure that alternative methods do not or have competitive performance with the state of the art. Empirical results are presented in several application domains. First, we use domain knowledge to assume a known form for multi-view relationships in the
task of gamma source detection. We aggregate the views by filtering their inferences collectively to perform classi cation. Second, we assume multi-view relationships are linear and learn them from data in a di fferent approach toward gamma source detection. Our method detects anomalies when these relationships are disrupted. Third, we relax the assumption
of linearity and propose a novel clustering method that finds cluster-wise linear relationships. This method discovers explanatory structure in a medical problem. Fourth, we extend this method to classifi cation and demonstrate its competitive performance on a load monitoring problem.
Quantum corrections to the dynamics of interacting bosons: beyond the truncated Wigner approximation

description: We develop a consistent perturbation theory in quantum fluctuations around the classical evolution of a system of interacting bosons. The zero order approximation gives the classical Gross-Pitaevskii equations. In the next order we recover the truncated Wigner approximation, where the evolution is still classical but the initial conditions are distributed according to the Wigner transform of the initial density matrix. Further corrections can be characterized as quantum scattering events, which appear in the form of a nonlinear response of the observable to an infinitesimal displacement of the field along its classical evolution. At the end of the paper we give a few numerical examples to test the formalism.

title: Electroplated titanium coatings
Creators: name: Bettley, Alison
Publisher: name: The Open University
Year: 1992

description: Electroplated titanium coatings on substrates such as steels have many potential industrial applications. The low cost of the substrate is combined with the excellent corrosion-resistance of the coating. However, titanium cannot be electrodeposited from aqueous systems because the hydrogen evolution reaction is always preferred. Proton-free media must be used. The electrodeposition of titanium from molten chlorides is well-known: large-scale titanium electrowinning processes have been operated, to produce high quality particulate material in an energy efficient way. The production of thick compact electroplates, however, has not been demonstrated consistently. It was therefore the objective of this work to determine the principal operating parameters for a titanium electroplating process based on a molten chloride (LiCl-KCl) bath. Studies of substrate oxide film reduction, the electro-reduction of divalent titanium, the nature of electrodeposits produced under various plating conditions, and the behaviour of the dissolving titanium anode have been undertaken. The following have been identified as the most important factors: (1) Substrate pre-treatment (2) Melt composition (titanium concentration, average valency, level of oxygen contamination) (3) Electrochemical parameters (chosen so as to combine good nucleation characteristics with avoidance of mass transport control effects) It has been demonstrated that thick, adherent, relatively smooth, compact coatings of titanium can be produced from molten chlorides at 450°C. Pulse plating and periodic current reversal are the most promising techniques for future optimisation with the objective of developing a commercial process.

Childhood obesity screening and management for primary care providers : a literature review
Creators: name: Le Gal, Laura
Publisher: name: The University of British Columbia
Year: 2018

description: Due to an overwhelming rise in childhood obesity (CO), primary care providers (PCPs) need to be cognisant of their pivotal role in assessing, diagnosing, and treating this chronic condition. However, research notes that PCPs face multiple barriers and conflicting recommendations for diagnosing CO resulting in insufficient assessment and management of this condition in children worldwide. The primary objective of this literature review is to evaluate current research and clinical practice guidelines regarding the screening and management of childhood obesity and provide a synthesis of the evidence. A total of 33 primary and secondary sources were reviewed and included in this literature review. Literature and clinical practice guidelines have identified that screening for obesity should begin in all patients two years and older on an annual basis. Screening should include body mass index (BMI), blood pressure (BP), and blood work as necessary. Optimal management of childhood obesity is the 5-2-1-0 program focusing on the education of families and patients about the importance of consuming five or more fruits and vegetables a day, reducing screen time to two hours a day, increasing activity to 60 minutes a day, and restricting all sugary beverage consumption. The aim of this literature review is to reduce obese children from developing diabetes mellitus, hypertension, and hyperlipidemia, in addition to other risk factors pertaining to remaining obese into adulthood and reduced life expectancy.

description: The level dynamics of pseudointegrable systems with different genus numbers $g$ is studied experimentally using microwave cavities. For higher energies the distribution of the eigenvalue velocities is Gaussian, as it is expected for chaotic systems with time-reversal symmetry, and shows no dependence on $g$. Also the curvature distribution $P(k)$ for large $k$ is decaying as it is expected for chaotic systems, i.e. $P(k) \sim |k|^{-3}$. For small $k$ an intermediate behavior is found, where $P(k)$ changes from integrable towards chaotic behavior with growing $g$.

description: We consider the effects of doping the S = 1/2 kagome lattice with static impurities. We demonstrate that impurities lower the number of low-lying singlet states, induce dimer-dimer correlations of considerable spatial extent, and do not generate free spin degrees of freedom. Most importantly, they experience a highly unconventional mutual repulsion as a direct consequence of the strong spin frustration. These properties are illustrated by exact diagonalization, and reproduced to semi-quantitative accuracy within a dimer resonating-valence-bond description which affords access to longer length scales. We calculate the local magnetization induced by doped impurities, and consider its implications for nuclear magnetic resonance measurements on known kagome systems.

description: No household that faces the dilemma of food shortage sit back in despair to allow the problem fester, but deploy various alternatives to combat food shortages. Such mechanisms are termed coping strategies - ranging from food-acquiring activities to change in eating behaviour or short term measures to long term mechanisms. The administration of these strategies is a sure indication that there is food security challenge and the coping strategies adopted defined the severity, type and the duration of food stress. This paper reviewed the coping strategies and objectively assesses their impact on the food security status of the region. Ravaged by the incidences of Boko Haram and communal crises, the northern region as a whole has got her share of induced poor food security situation that have manifested in the reduction in food production, wide spread hunger and malnutrition in some parts of the region. The coping strategies deployed include overt reliance on less preferred and less expensive foods, borrowing or reliance on help from friends or relatives (with PCS scores of 2), limiting the portion size at mealtimes, rationing adult meals and reduction in the number of meals eaten in a day (PCS score 3). These strategies indicate that the households in the regions as a whole deploy more often, less severe coping strategies, implying that food security crisis could be easily reversed if appropriate interventions such as increased support to agricultural sector via input support and improved security apparatus are put in place.
title: Stories of what is to come: the future in film and television 1959-1989
Creators: name: Bonner, Frances Jane
Publisher: name: The Open University
Year: 1991

description: The thesis examines films, television programmes and associated newspaper articles from the period 1959-1989 to discover how the future has been talked about in popular discourses. It considers both fiction and nonfiction in the areas of defence, nuclear issues, ecological catastrophes, space and artificial beings. It is particularly concerned to contrast scientific discourse with science fiction to discover how the distinction between them is maintained when the temporal setting is the future and whatever is asserted or depicted is characterised by not yet having happened. The thesis begins by investigating the discursive struggle over the naming of the US military policy both Star Wars and SDI. It uses the concept of professional language and Michel Foucault's arguments about regimes of truth to explain the status of the more scientific term, while the popularity and success of the film are advanced as reasons for the appeal of the popular title. The following chapters attempt to discover whether this example is charcteristic or an oddity. The examination of the presentation of potential eco-catastrophes, particularly in TV science programmes finds minimal variation and piecemeal presentation being used in an attempt to separate scientific discourse from SF and emphasise certainty. In looking at nuclear discourse the competing claims of the defence establishment and those people making nuclear war dramas for TV to speak with authority about the future are investigated to try to understand why there is such a paucity of depictions of the nuclear future. It is discovered that talking about the future in space shifted with economic discourse became more dominant than scientific, but that this did not apply to those fictions, like Star Trek, which were constrained by precursors from the 1960s. These are the major instances of an optimistic future. In considering the case of artificial beings, changes are found within the fictions as certain categories of being become scientifically more feasible. An analogy with colonial discourse and the concept 'hybridity' proves particularly useful. The thesis concludes by finding hybrids of fiction and non-fiction, scientific and science fictional discourses most characteristic of popular discourses about the future.

title: Tectonics and Magmatism in the Basin and Range Province of the Western United States
Creators: name: Bradshaw, Timothy Keith
Publisher: name: The Open University
Year: 1992

description: The nature and geochemistiy of Miocene magmatism coeval to major extension is studied in detail along the Colorado River between 34-36°N. A tectonomagmatic model is proposed and developed into a general model for the Basin and Range. Mafic magmas are divided into three groups on the basis of geochemistry: group 1 (most recent) magmas have [Nb/La] >1, and Sr and Pb isotope ratios indistinguishable from OIB, these basalts are thought to derive by <10% melting of an asthenospheric source; group 2 & 3 magmas have [Nb/La] <1 and elevated Sr and Pb isotope ratios suggesting a subcontinental lithospheric mantle (SCLM) source. Group 3 magma geochemistry is rather variable, but consistent with an increasing degree of partial melting (1-14%) of a trace element enriched garnet Iherzolite source with time. Group 2 magmas have HREE, Y and Sc enriched relative to groups 1 & 3, although relatively depleted LILE and LREE. It is argued that the group 2 & 3 sources are related by depth and that melting in the SCLM progressed to shallower, less enriched, levels with time. Intermediate to high silica magmas display a positive 87Sr/86Sr vs. Si02 correlation and evolution to moderately alkaline compositions. Fractionation and AFC processes are insufficient to replicate the observed geochemical variations, instead these magmas are modelled by binary mixing between mafic and silicic endmember melts. The distribution and volume of these ‘hybrid’ magmas suggests that a ductile melting zone developed in the middle crust, which dominated the Miocene crustal extension. Geophysical evidence, combined with plate tectonic reconstructions and the changes in magma geochemistry with time, indicate that plate tectonics was the driving force behind extension and magmatism. The influence of a mantle plume is thought to be unnecessary, rather SCLM melting was initiated by heat input from the asthenosphere as it re-equilibrated to fill the ‘void’ left by the northward migration of the Farallon Plate beneath the W. USA.

description: The aim of the present thesis was the analysis of Aristotle’s physical world and the study of its parts. Through this study emerges the domination of the Aristotelian universe and the refutation of the Atomic system. Initially, the basic principles -for instance the definition of motion- and the features of Aristotle’s physical system, such as the structure of the earthly and the heavenly world, the teleology and its part in nature, the luck and chance, the famous Aristotelian causes and the Aristotelian theology, are presented extensively. As mentioned, the domination of Aristotle’s physical and teleological universe leading to the refutation of the Atomic system is a factor that is thoroughly described in the present thesis. Finally, the timelessness of Aristotle’s doctrines on nature and their contribution to contemporary scientific doctrines of Physics are also examined.

description: WISEA J080822.18-644357.3, an M star in the Carina association, exhibits extreme infrared excess and accretion activity at an age greater than the expected accretion disk lifetime. We consider J0808 as the prototypical example of a class of M star accretion disks at ages $\gtrsim 20$ Myr, which we call ``Peter Pan'' disks, since they apparently refuse to grow up. We present four new Peter Pan disk candidates identified via the Disk Detective citizen science project, coupled with \textit{Gaia} astrometry. We find that WISEA J044634.16-262756.1 and WISEA J094900.65-713803.1 both exhibit significant infrared excess after accounting for nearby stars within the 2MASS beams. The J0446 system has $>95\%$ likelihood of Columba membership. The J0949 system shows $>95\%$ likelihood of Carina membership. We present new GMOS optical spectra of all four objects, showing possible accretion signatures on all four stars. We present ground-based and \textit{TESS} lightcurves of J0808 and 2MASS J0501-4337, including a large flare and aperiodic dipping activity on J0808, and strong periodicity on J0501. We find Pa$β$ and Br$γ$ emission indicating ongoing accretion in near-IR spectroscopy of J0808. Using observed characteristics of these systems, we discuss mechanisms that lead to accretion disks at ages $\gtrsim20$ Myr, and find that these objects most plausibly represent long-lived CO-poor primordial disks, or ``hybrid'' disks, exhibiting both debris- and primordial-disk features. The question remains: why have gas-rich disks persisted so long around these particular stars?

description: There have been fluctuations in the exchange rate of Naira to other world major currencies especially the US Dollar over time. The implication of this on agricultural exports is unknown. This study determined the effect of exchange rate returns volatility on Nigeria's agricultural export performance using annual data from 1980-2015 sourced from CBN and FAOSTAT. The ARCH-LM test was carried out to establish the presence ofheteroscedasticity in the exchange rate return series as revealed by the significant F-statistic and the nR2• The GARCH (1, 1) model was used to generate the exchange rate return volatiiity series which was subsequently incorporated into the ARDL model for determining factors affecting agricultural exports (cocoa and rubber). The Bound test revealed longrun relationship among variables. Results indicated that exchange rate return volatility did not significantly affect exports both in the short-run and the long-run. This may be partially attributed to the inelastic nature of agricultural commodities' supply particularly in the short run. It was also revealed that there is a positive and significant relationship between exchange rate, inflation, GDP, domestic prices, world prices and agricultural export. The study recommended among others that fiscal and monetary policies such as lower interest rate and import restriction on certain agricultural products should be adopted by the relevant authorities alongside other measures which may improve local production to meet both international and local demands, thereby, improving agricultural export and raising foreign exchange earnings which may translate to sustainable economic growth and lead the country out of recession.

description: Over the past 15 years, the Government has adopted an economic policy that resulted in a sharp increase in the importation of food items. This massive importation trend had major consequences for the economy. Therefore, this study assessed the determinants of food importation in Cameroon (l 995-2015). Data were collected from secondary sources, analysed using vector error correction model (VECM), variance decomposition and impulse response. The results showed that agricultural production significantly decreased food importation while exchange rate increased food importation in the long run and short run. The result further showed that agricultural production is the most contributing factor to food importation both in the long and short run. It was recommended that taxes on food importation should be increased while exchange rate policy should also be reviewed in order to discourage importation of food into the country.

description: Η παρούσα μελέτη αποτελεί βιβλιογραφική έρευνα σε σχέση με τα ηθικά, νομικά και ιατρικά ζητήματα που αφορούν την άνοια, με έμφαση στη νόσο Alzheimer. Η άνοια αποτελεί ένα από τα σημαντικότερα προβλήματα υγείας στις μέρες μας, το οποίο πρόκειται να επιταθεί λόγω της αύξησης του προσδόκιμου ζωής και της αναμενόμενης αύξησης του αριθμού των πασχόντων. Η νόσος αυτή πλήττει μεταξύ των άλλων την αξιοπρέπεια του ασθενούς και επιβαρύνει σωματικά, συναισθηματικά, οικονομικά και κοινωνικά τόσο τον ίδιο όσο και τους οικείους του. Πέρα από την εξέλιξη της έρευνας και την ανακάλυψη αποτελεσματικών θεραπειών για τη νόσο, η πολιτεία πρέπει να στηρίζει τους φροντιστές των ασθενών, οι οποίοι επιφορτίζονται με ένα μεγάλο μέρος του φορτίου που προκύπτει από τα καθημερινά πρακτικά προβλήματα, τα οικονομικά ζητήματα και τα προβλήματα βιοηθικής φύσεως που προκαλεί η νόσος. Η αντιμετώπιση αυτή πρέπει να είναι συνολική, με τη συμμετοχή των ειδικών επαγγελματιών υγείας, των συλλόγων φροντιστών και της πολιτείας. Ελπίζουμε ότι τα επόμενα χρόνια η κατάσταση σε σχέση με τη νόσο θα βελτιωθεί σημαντικά, για το καλό των πασχόντων, αλλά και όλης της κοινωνίας.
description: The present study is a literature review on the ethical, legal and medical issues related to dementia, with an emphasis on Alzheimer's disease. Dementia is one of the most important health problems nowadays, which is going to be exacerbated due to the increase in life expectancy and the expected increase in the number of sufferers. This disease affects, among other things, the dignity of the patient and burdens physically, emotionally, financially and socially both himself and his relatives. In addition to evolving research and discovering effective treatments for the disease, the state must support patient caregivers, who are responsible for much of the burden of everyday practical, financial, and bioethical issues caused by the disease. This treatment must be comprehensive, with the participation of health professionals, caregivers' associations and the state. We hope that in the coming years the situation in relation to the disease will improve significantly, for the good of the sufferers, but also of society as a whole.

description: We synthesize a series of CVD h-BN films and perform critical infrared spectroscopic characterization. For high-temperature (HT, Temp = 1400 degrees) grown h-BN thin film only E1u-mode infrared phonon is activated demonstrating highly aligned 2D h-BN planes over large area, whereas low-temperature (LT, Temp = 1000 degrees) grown film shows two phonon peaks, E1u and A2u, due to stacking of h-BN plane at tilted angle. For CVD graphene transferred on HT h-BN/SiO2/Si substrate, interband transition spectrum s1 shifts strongly to lower energy compared with that on LT h-BN/SiO2/Si and on bare SiO2/Si substrate, revealing that residual carrier density n in graphene is suppressed by use of HT h-BN layer. Also the interband transition width of s1 defined by effective temperature is reduced from 400 K for G/SiO2/Si to 300 K for HT h-BN/SiO2/Si. The behaviors of n and effective temperature show that HT h-BN film can decouple CVD graphene from the impurity and defect of SiO2 leading to large scale free-standing like graphene.

description: This study analyzed the relationship among producer prices, area harvested and yield of cassava in Nigeria. The study used annual time series data spanning from 1991 to 2014. Results from Augmented Dickey Fuller test showed that the series were integrated of order one, 1(1 ). Johansen cointegration test showed there was no long-run relationship among the variables. Results from the VAR estimates showed that producer prices have significant influence on area harvested and yield of cassava even though there was no long-run relationship among the variables during the period of study. Also the variance decomposition analyses showed that over time the results reveal that only about 26.21 and 27.91 percent of changes in producer prices is explained by changes in area harvested and yield respectively. This implies that producer prices are mainly influenced by changes in its own shock and not changes in area harvested and yield. Results showed that there exist bidirectional causalities between yield and area harvested, while a unidirectional causality was found to exist between producer prices and area harvested as well as between yield and producer prices. Consequently, given the influence of producer prices on the area harvested and yield of cassava, price policies that will encourage farmers to put additional area into the cultivation of cassava ought to be promoted.
The impact of poverty on children’s educational potential

description: About one in four Canadian children live in poverty, which means poverty is present in the Canadian classroom. The purpose of this study is to better understand the impact of poverty on Canadian children, particularly in education, so teachers are better equipped to teach their students, regardless of their socioeconomic backgrounds, and to combat poverty. The research question is: How does poverty impact children’s educational potential? This study is an extended literature review using peer-reviewed journal articles published this century, as well as other sources, such as Statistics Canada. The intention was to as much as possible use Canadian sources and focus on children. A critical-interpretivist viewpoint is used to present the material. The body of the study focuses specifically on poverty in Canada. Poverty leads to the problem of food insecurity, which in turn results in malnutrition. Malnutrition is concerned with nutrient deficiencies, hidden hunger, and obesity. These negatively affect a family, especially the children, struggling with poverty. The study closes with the implications of poverty on Canadian children’s lives and how it impacts them in the classroom. It outlines the action that can be taken by government, business, community, and education. It delineates the strategies communities and education can utilize to improve the lives of children and their families who live in poverty, moving forward to eradicate poverty in Canada by using individual, school, and community grassroots efforts. The study concludes with a home economics educator’s summary and reflections.
Evolution of the macroscopically entangled states in optical lattices

description: We consider dynamics of boson condensates in finite optical lattices under a slow external perturbation which brings the system to the unstable equilibrium. It is shown that quantum fluctuations drive the condensate into the maximally entangled state. We argue that the truncated Wigner approximation being a natural generalization of the Gross-Pitaevskii classical equations of motion is adequate to correctly describe the time evolution including both collapse and revival of the condensate.

description: The study investigated market integration of natural rubber across three major State markets, namely Edo, Delta and Akwa-Ibom, of the Nigeria us~ng Johansen Co-integration test, and Granger Causality by VECM. Empirical results for average monthly retail price data (N/kg) of natural rubber, covering the period January, 2005 to December, 2015 (11 years) indicated that Price series were not stationary in their level form. The Delta State price appeared to respond faster to changes than the Edo and Akwa-Ibom price. The study also showed the existence of co-integration among the studied markets. Granger causality showed unidirectional causality between Akwa-Ibom and Delta bidirectional for the other two market pairs. The significant coefficient of the error correction term showed immediate adjustment to changes in the longrun equilibrium.

description: Η εικονικοποίηση δικτύων και τα εργαλεία προσομοίωσης όπως ο προσομοιωτής GNS3, δίνουν τη δυνατότητα να δοκιμαστούν απλά σενάρια που απαιτούν διαμόρφωση αλλά και να εκτελεστούν πιο περίπλοκα σενάρια δικτύων μέσω εικονικών εξοπλισμών, δρομολογητών και διακοπτών μέσω μιας εικονικής κονσόλας. Καθώς υπάρχουν αρκετές αδυναμίες για τη πρόσβαση σε πραγματικό εξοπλισμό λόγω του υψηλού κόστους αλλά και των δυσλειτουργιών που πολλές φορές παρουσιάζουν. Τα προγράμματα εικονικοποίησης δικτύων επιτρέπουν στους χρήστες να διαμορφώσουν μια συσκευή δικτύου με το ίδιο λειτουργικό σύστημα που χρησιμοποιεί και μια πραγματική συσκευή δικτύου. Επίσης οι εικονικοί προσομοιωτές είναι αρκετά χρήσιμοι ώστε να χρησιμοποιηθούν για δοκιμές εφαρμογών πριν παραδοθούν στους χρήστες. Ωστόσο η διαμόρφωση της τοπολογίας του εικονικού δικτύου απαιτεί αυστηρές λειτουργίες και διαδικασίες. Στόχος αυτής της διπλωματικής εργασίας είναι να εκτελεστούν βασικά σενάρια που καλύπτουν ένα ευρύ φάσμα των λειτουργιών δικτύου μέσω του προσομοιωτή Graphical Network Simulator 3 (GNS3) καθώς και η ανάλυση των κύριων τμημάτων των δικτύων επικοινωνιών.
description: Network virtualization and simulation tools such as the GNS3 simulator allow to test simple configuration scenarios and more complex network scenarios through virtual equipment, routers and switches with a virtual console. There are several weaknesses in accessing real equipment due to the high cost but also the malfunctions that they often present. Network virtualization programs allow users to configure a network device with the same operating system as a real network device. Virtual simulators are also useful to be used for application testing before being delivered to users. However, the configuration of the virtual network topology requires strict functions. The aim of this project is to execute basic scenarios covering a wide range of network operations with the Graphical Network Simulator 3 (GNS3) and the analysis of the main parts of the communication networks.
