Linking Data Strategies for the José Maceda Music Collection (JMC) at the UP Center for Ethnomusicology, Manila
Creators: name: Flicker, Katharina
Publisher: name: Zenodo
Year: 2024

description: Discover how an ASEA-UNINET project aims to bridge the gaps in South-East Asian musicological research. Despite the rich diversity of musical heritage across the region, resources are scattered and stored in varied formats, making comprehensive research challenging. Thus, a standardized data management strategy is being developed to facilitate seamless (meta) data sharing among partner organizations, revolutionizing the accessibility and efficiency of music research, all while keeping in mind the need to facilitate trust, not only in the data, but the infrastructures and organizations as well.

description: This paper investigates the capacity region of the three-receiver AWGN broadcast channel where the receivers (i) have private-message requests and (ii) may know some of the messages requested by other receivers as side information. We first classify all 64 possible side information configurations into eight groups, each consisting of eight members. We next construct transmission schemes, and derive new inner and outer bounds for the groups. This establishes the capacity region for 52 out of 64 possible side information configurations. For six groups (i.e., groups 1, 2, 3, 5, 6, and 8 in our terminology), we establish the capacity region for all their members, and show that it tightens both the best known inner and outer bounds. For group 4, our inner and outer bounds tighten the best known inner bound and/or outer bound for all the group members. Moreover, our bounds coincide at certain regions, which can be characterized by two thresholds. For group 7, our inner and outer bounds coincide for four members, thereby establishing the capacity region. For the remaining four members, our bounds tighten both the best known inner and outer bounds.

description: Background:The US Preventive Services Task Force (USPSTF) 2021 updated recommendations on lung cancer screening with chest computed tomography to apply to individuals 50-80 years of age (previously 55-80 years), with a ≥20 pack-year history (previously ≥30), whether currently smoking or quit ≤15 years ago. Despite being at higher risk for lung cancer, persons with HIV (PWH) were not well-represented in the National Lung Screening Trial, which informed the USPSTF 2013 recommendations. It is unknown or unclear how PWH are affected by the 2021 recommendations.Setting:This study was a retrospective analysis of PWH with and without lung cancer in the Women's Interagency HIV Study and the Multicenter AIDS Cohort Study.Methods:We identified PWH, ages 40-80 years, who currently or previously smoked, with (cases) and without lung cancer (noncases). The sensitivity and specificity of the old, new, and alternative screening criteria were evaluated in each cohort.Results:We identified 52 women and 19 men with lung cancer and 1950 women and 1599 men without lung cancer. Only 11 women (22%) and 6 men (32%) with lung cancer met 2013 screening criteria; however, more women (22; 44%) and men (12; 63%) met 2021 criteria. Decreased age and tobacco exposure thresholds in women further increased sensitivity of the 2021 criteria.Conclusions:The 2021 USPSTF lung cancer screening recommendations would have resulted in more PWH with lung cancer being eligible for screening at the time of their diagnosis. Further investigation is needed to determine optimal screening criteria for PWH, particularly in women.

description: We report a study of selenospinel Cu$_{6-x}$Fe$_{4+x}$Sn$_{12}$Se$_{32}$ ($x$ = 0, 1, 2) single crystals, which crystalize in a cubic structure with the $Fd\overline{3}m$ space group, and show typical semiconducting behavior. The large discrepancy between the activation energy for electrical conductivity $E_ρ$ (32.3 $\sim$ 69.8 meV), and for thermopower $E_\textrm{S}$ (3.2 $\sim$ 11.5 meV), indicates a polaronic transport mechanism between 350 and 50 K. With decreasing temperature, it evolves into variable-range hopping conduction. Furthermore, the heat capacity shows a hump around 25(5) K and diverges from the Debye $T^3$ law at low temperatures, indicating the observation of structural glassy features in these crystalline solids.

description: Bloch theorem states the impossibility of persistent electric currents in the ground state of nonrelativistic fermion systems. We extend this theorem to generic systems based on the gauged particle number symmetry and study its consequences on the example of chiral transport phenomena. We show that the chiral magnetic effect can be understood as a generalization of the Bloch theorem to a nonequilibrium steady state, similarly to the integer quantum Hall effect. On the other hand, persistent axial currents are not prohibited by the Bloch theorem and they can be regarded as Pauli paramagnetism of relativistic matter. An application of the generalized Bloch theorem to quantum time crystals is also discussed.

Counting on proportions? An examination of the interplay between proportional reasoning and whole-number information
Creators: name: Abreu Mendoza, Roberto Alfonso
Publisher: name: No Publisher Supplied
Year: 2023

description: Adults, elementary school children, and even preschoolers can readily compare nonsymbolic, non-countable, continuous proportions. This exceptional nonsymbolic ability is in stark contrast with students' difficulty in understanding symbolic proportions, particularly fractions. Although students are introduced to fractions in the third grade, middle schoolers, and even college students struggle understanding fractions. An exciting, promising approach to ameliorate students' struggles with fractions is to leverage nonsymbolic proportional reasoning to improve their understanding of fraction magnitudes. In a recent review, we found that nonsymbolic proportional interventions can lead to small-to-large effect size improvements in fraction knowledge. Nonetheless, not all nonsymbolic formats engage proportional reasoning similarly. In contrast tocontinuous proportions, older children and adults have trouble comparing countable, discretized proportions, particularly when there is misleading counting information (also referred to as whole-number information) contradicting the proportional magnitude. When working with these proportions, students tend to employ erroneous whole-number strategies instead of engaging with proportional magnitudes. If we aim to improve students' understanding of fractions through nonsymbolic instruction, we need to determine the cognitive skills that lead to skillful nonsymbolic proportional reasoning and provide a comprehensive explanation for the relationship between nonsymbolic and symbolic proportional skills. In Chapter 2, I first aimed to determine the cognitive mechanisms contributing to successful nonsymbolic discretized proportional reasoning among second graders. In particular, I examined the role of inhibitory control, the executive function that allows overcoming automatic responses, as this type of nonsymbolic proportions requires disregarding misleading counting information. Behavioral correlation studies indicate a moderate relation between nonsymbolic and symbolic proportional magnitude understanding; however, no work has contrasted the different contributions of continuous and discretized formats. To inquire about these distinct contributions, I used online behavioral tasks (Chapter 3) and functional imaging methodologies (Chapter 4). Specifically, Chapter 3 examines the relations between middle schoolers' nonsymbolic and symbolic proportional reasoning using correlational and cluster analyses. Finally, Chapter 4 uses a multivoxel pattern approach, representational similarity analysis, to determine whether adults' brain patterns while comparing fractions resemble those of continuous or discretized comparison skills. Together, the work of my dissertation provides a detailed explanation of the relation between nonsymbolic and symbolic proportional skills, which, in turn, could offer insights for educational interventions aiming to enhance fraction understanding.

description: Objective: To evaluate the associations of HIV infection with preterm birth (PTB), and of HIV antiretroviral therapy (ART) with PTB. Methods: We analysed singleton live-born pregnancies among women from 1995 to 2019 in the Women's Interagency HIV Study, a prospective cohort of US women with, or at risk for, HIV. The primary exposures were HIV status and ART use before delivery [none, monotherapy or dual therapy, or highly active antiretroviral therapy (HAART)]. The primary outcome was PTB < 34 weeks, and, secondarily, < 28 and < 37 weeks. We analysed self-reported birth data, and separately modelled the associations between HIV and PTB, and between ART and PTB, among women with HIV. We used modified Poisson regression, and adjusted for age, race, parity, tobacco use and delivery year, and, when modelling the impact of ART, duration from HIV diagnosis to delivery, nadir CD4 count, and pre-pregnancy viral load and CD4 count. Results: We analysed 488 singleton deliveries (56% exposed to HIV) to 383 women. The risk of PTB < 34 weeks was similar among women with and without HIV, but the risk of PTB < 37 weeks was higher [32% vs. 23%; adjusted risk ratio (aRR) = 1.43; 95% confidence interval (CI): 1.07–1.91] among women with HIV. The risk of PTB < 34 weeks was lower among women with HIV receiving HAART than among those receiving no ART (7% vs. 26%; aRR:0.19; 95% CI: 0.08–0.44). The associations between HAART and PTB < 28 and < 37 weeks were similar. Conclusions: Antiretroviral therapy exposure was associated with a decreased risk of PTB among a US cohort of women with HIV. Given the growing concerns about ART and adverse pregnancy outcomes, this finding that ART may be protective for PTB is reassuring.

The interior spacetime appears in the sense of complementarity because of special features revealed by the microscopic degrees of freedom when viewed from a semiclassical standpoint. The relation between quantum mechanics and the equivalence principle is subtle, but they are still consistent.

description: Objective:Little is known about the prevalence and treatment of premature and early menopause among people with HIV. We described premature and early menopause and subsequent hormonal treatment in a longitudinal cohort of women living with or at risk for HIV in the US.Methods:Data from the Women's Interagency HIV Study between 2008 and 2020 were analyzed to describe premature and early menopause among cohort participants under the age of 51.Results:Of 3,059 eligible women during the study period, 1% (n=35) underwent premature menopause before age 41, 3% (n=101) underwent menopause between ages 41 and 46, and 21% (n=442) underwent menopause between ages 46 and 50, inclusive. Of participants who experienced menopause before age 41, between age 41 and 45, and between ages 46 and 50, 51%, 24%, and 7% (respectively) received either menopausal hormone therapy or hormonal contraception.Conclusion:These findings suggest that disparities in receipt of recommended hormone therapy for premature and early menopause may contribute, in part, to evident health disparities, such as cardiovascular disease, osteoporosis, and overall mortality. They also suggest a substantial need for education among people experiencing early menopause and their providers, with the goal of improving access to hormone therapy based on guidelines to address health disparities and minimize future health consequences.

description: The solvent casted Poly(ethylene glycol) (PEG) and Poly(lactic acid) (PLA) blend was recrystallized by the thermal treatment of a heating and cooling cycle. The high PEG content blend (30\%wt) showed a striking dispersion behavior, that the materials rapidly dispersed and dissolved in the aqueous environment in a few hours. This phenomenon has not been reported by others, and was not observed in low PEG content samples of 5\%, 10\%, and 20\%, or quenched(amorphous) samples. We hypothesized the mechanism that the chain rearrangement during the thermal treatment leads to the phase separation. And with the phase separation in the recrystallized samples, the PEG potions rapidly dissolved in the aqueous environment, left out the small PLA spherulites being separated and dispersed in the solution. The same underlying reason can also be inferred from the degradation behaviors of other samples. Characterizations of DSC, XRD, and SEM have been done to validate our hypothesis.

description: The need to estimate smooth probability distributions (a.k.a. probability densities) from finite sampled data is ubiquitous in science. Many approaches to this problem have been described, but none is yet regarded as providing a definitive solution. Maximum entropy estimation and Bayesian field theory are two such approaches. Both have origins in statistical physics, but the relationship between them has remained unclear. Here I unify these two methods by showing that every maximum entropy density estimate can be recovered in the infinite smoothness limit of an appropriate Bayesian field theory. I also show that Bayesian field theory estimation can be performed without imposing any boundary conditions on candidate densities, and that the infinite smoothness limit of these theories recovers the most common types of maximum entropy estimates. Bayesian field theory is thus seen to provide a natural test of the validity of the maximum entropy null hypothesis. Bayesian field theory also returns a lower entropy density estimate when the maximum entropy hypothesis is falsified. The computations necessary for this approach can be performed rapidly for one-dimensional data, and software for doing this is provided. Based on these results, I argue that Bayesian field theory is poised to provide a definitive solution to the density estimation problem in one dimension.

title: Studies on the germination and dormancy of Polygonum persicaria L
Creators: name: Mensah, Stephen Ikechukwu
Publisher: name: University of Glasgow
Year: 1984
Subjects: subject: Plant sciences.

description: Studies on the germination and the nature of dormancy of achenes of Polygonum persicaria were carried out. The release from dormancy was investigated by physical and chemical treatments, environmental factors (temperature and light) and the application of plant hormones. The imposition of dormancy on non-dormant achenes was examined by prolonged dark incubation at supraoptimal temperature, and also by drying treatments. The physical (surgical) treatments, such as cutting the tip of achenes or removal of the pericarp, promoted germination of unchilled achenes, while chemical treatments with calcium hypochlorite, and nitrogenous compounds such as nitrates, thiourea, hydroxylamine hydrochloride, and respiratory inhibitors like cyanide and azide, failed to break the dormancy of unchilled achenes. However, unchilled achenes responded positively to treatment with nitrite and hydrogen peroxide, giving an enhanced and significant germination. Treatment with environmental factors such as temperature and light (white or red) on unchilled achenes illustrated that the population consists of at least four physiological polymorphic components, namely. Dark; Light; Alternating Temperature (dark), and Alternating Temperature plus Light subpopulations. Stratification treatment resulting in complete dark germination when transferred to higher temperature is more effective at 4°C than 10°C. Germination is enhanced at alternating temperatures in the dark in contrast to constant temperatures. However, a high temperature of 40°C is lethal for germination. Exogenous application of GA3, GA4+7, ethylene or nonanoic acid (C9) did not influence the germination of unchilled achenes. In contrast, kinetin appears to promote germination. Moreover, combined treatments of red light and kinetin with or without GA3 gave the greatest germination. Results from applying G3 during or after stratification did not indicate the involvement of gibberellin during or after chilling. Also, treatment with growth retardants (B995, CCC, AMO 1618, and Ancymidol) argue against gibberellin involvement during or after stratification. The results of applying ABA during stratification or germination indicated that growth processes, i.e. radicle elongation, are inhibited and not germination sensu stricto. The results of, prolonged dark incubation at supraoptimal temperature at 40°C indicated that the effect could be considered as thermo inhibition rather than thermodormancy. However, drying treatment induces secondary dormancy.

This paper builds on the works of Borkar and Perkins & Leslie. The framework presented herein is more general as compared to the synchronous two timescale framework of Perkins \& Leslie, however the assumptions involved are easily verifiable. As an application, we use this framework to analyze the two timescale stochastic approximation algorithm corresponding to the Lagrangian dual problem in optimization theory.

description: In countries with high human immunodeficiency virus (HIV) prevalence, up to 30% of pregnant women are living with HIV, with fetal exposure to both HIV and antiretroviral therapy during pregnancy. In addition, pregnant women without HIV but at high risk of HIV acquisition are increasingly receiving HIV preexposure antiretroviral prophylaxis (PrEP). Investments are being made to establish and follow cohorts of children to evaluate the long-term effects of in utero HIV and antiretroviral exposure. Agreement on a key set of definitions for relevant exposures and outcomes is important both for interpreting individual study results and for comparisons across cohorts. Harmonized definitions of in utero HIV and antiretroviral drug (maternal treatment or PrEP) exposure will also facilitate improved classification of these exposures in future observational studies and clinical trials. The proposed definitions offer a uniform approach to facilitate the consistent description and estimation of effects of HIV and antiretroviral exposures on key child health outcomes.

description: Background: As employment, financial status, and residential location change, people can gain, lose, or switch health insurance coverage, which may affect care access and health. Among Women's Interagency HIV Study participants with HIV and participants at risk for HIV attending semiannual visits at 10 U.S. sites, we examined whether the prevalence of coverage types and rates of coverage changes differed by HIV status and Medicaid expansion in their states of residence. Methods: Geocoded addresses were merged with dates of Medicaid expansion to indicate, at each visit, whether women lived in Medicaid expansion states. Age-adjusted rate ratios (RRs) and rate differences of self-reported insurance changes were estimated by Poisson regression. Results: From 2008 to 2018, 3,341 women (67% Black, 71% with HIV) contributed 43,329 visits at aged less than 65 years (27% under Medicaid expansion). Women with and women without HIV differed in their proportions of visits at which no coverage (14% vs. 19%; p < .001) and Medicaid enrollment (61% vs. 51%; p < .001) were reported. Women in Medicaid expansion states reported no coverage and Medicaid enrollment at 4% and 69% of visits, respectively, compared with 20% and 53% of visits for those in nonexpansion states. Women with HIV had a lower rate of losing coverage than those without HIV (RR, 0.81; 95% confidence interval [CI], 0.70 to 0.95). Compared with nonexpansion, Medicaid expansion was associated with lower coverage loss (RR, 0.62; 95% CI, 0.53 to 0.72) and greater coverage gain (RR, 2.32; 95% CI, 2.02 to 2.67), with no differences by HIV status. Conclusions: Both women with HIV and women at high risk for HIV in Medicaid expansion states had lower coverage loss and greater coverage gain; therefore, Medicaid expansion throughout the United States should be expected to stabilize insurance for women and improve downstream health outcomes.

description: Abstract: This study investigates the causes of students' failure in high school examinations in Hargeisa, Somaliland. Utilizing a descriptive cross-sectional research design, data were gathered from 142 respondents through structured questionnaires. The research focused on identifying key factors that contribute to poor academic performance, including student-related factors such as discipline and truancy, teacher-related factors like teaching quality and classroom attendance, and school-related factors including administration quality and availability of physical facilities. The findings indicate that while student- and teacher-related factors had a moderate impact, school-related factors played a more significant role in influencing exam performance. Specific causes of failure include inadequate preparation time, high stress levels, poor study habits, and lack of access to educational resources. Statistical analyses, including Chi-square, ANOVA, and regression tests, were used to explore relationships between socio-economic background and performance, identifying school-related factors as the strongest predictor of academic success. The study recommends improving school infrastructure, enhancing teacher training, and increasing access to learning materials to reduce failure rates.

description: We are interested in situations where the Hausdorff measure and Hausdorff content of a set are equal in the critical dimension. Our main result shows that this equality holds for any subset of a self-similar set corresponding to a nontrivial cylinder of an irreducible subshift of finite type, and thus also for any self-similar or graph-directed self-similar set, regardless of separation conditions. The main tool in the proof is an exhaustion lemma for Hausdorff measure based on the Vitali Covering Theorem. We also give several examples showing that one cannot hope for the equality to hold in general if one moves in a number of the natural directions away from `self-similar'. For example, it fails in general for self-conformal sets, self-affine sets and Julia sets. We also give applications of our results concerning Ahlfors regularity. Finally we consider an analogous version of the problem for packing measure. In this case we need the strong separation condition and can only prove that the packing measure and $δ$-approximate packing pre-measure coincide for sufficiently small $δ>0$.

description: The aim of this study is to determine the morphotypology of Algerian handball players who are members of the national team. We investigated 15 male athletes, aged 22 to 32 years and practicing a regular training from 5 to 20 years with more than 500 hours per year.

We used the anthropometric method to select the most important morphological parameters in order to propose them for future selection. Principal component analysis allowed us to approach the problem of sports morphology through statistics. We found that this analysis effectively highlights the fact that by simultaneously considering several morphological characteristics, it is possible to determine the "typical profile" of a given sport and to discriminate between the playing positions that we studied

description: We study the limitations of deterministic programmability of quantum circuits, e.g., quantum computer. More precisely, we analyse the programming of quantum observables and channels via quantum multimeters. We show that the programming vectors for any two different sharp observables are necessarily orthogonal, whenever post-processing is not allowed. This result then directly implies that also any two different unitary channels require orthogonal programming vectors. This approach generalizes the well-known orthogonality result first proven by Nielsen and Chuang. In addition, we give size-bounds for a multimeter to be efficient in quantum programming.

description: The use of molecular markers has revolutionized plant breeding in India by enhancing crop productivity,resilience, and sustainability. This paper explores the role of molecular markers in accelerating plant breedingprograms, focusing on their impact on major crops like rice, wheat, chickpea, pigeon pea, and cotton. ThroughMarker-Assisted Selection (MAS), researchers have successfully developed varieties with improved traitssuch as disease resistance, drought tolerance, and fibre quality. Case studies highlight the development ofbacterial blight-resistant rice, rust-resistant wheat, drought-tolerant chickpea, disease-resistant pigeon pea, andhigh-quality cotton. Despite these successes, challenges such as high costs, limited infrastructure, andknowledge transfer barriers remain. Future prospects include the integration of advanced technologies likegenomic selection, genome editing, and climate-smart agriculture, which promise further advancements incrop breeding. Addressing existing challenges and leveraging emerging technologies will be crucial formaximizing the benefits of molecular markers and ensuring their widespread adoption to meet India’sagricultural demands and food security needs.

description: Item Response Theory (IRT) has been proposed within the field of Educational Psychometrics to assess student ability as well as test question difficulty and discrimination power. More recently, IRT has been applied to evaluate machine learning algorithm performance on a single classification dataset, where the student is now an algorithm, and the test question is an observation to be classified by the algorithm. In this paper we present a modified IRT-based framework for evaluating a portfolio of algorithms across a repository of datasets, while simultaneously eliciting a richer suite of characteristics - such as algorithm consistency and anomalousness - that describe important aspects of algorithm performance. These characteristics arise from a novel inversion and reinterpretation of the traditional IRT model without requiring additional dataset feature computations. We test this framework on algorithm portfolios for a wide range of applications, demonstrating the broad applicability of this method as an insightful algorithm evaluation tool. Furthermore, the explainable nature of IRT parameters yield an increased understanding of algorithm portfolios.
Resolving the Tevatron Top Quark Forward-Backward Asymmetry Puzzle: Fully Differential Next-to-Next-to-Leading-Order Calculation

description: We determine the dominant missing Standard Model (SM) contribution to the top quark pair forward-backward asymmetry at the Tevatron. Contrary to past expectations, we find a large, around 27%, shift relative to the well-known value of the inclusive asymmetry in next-to-leading order (NLO) QCD. Combining all known Standard Model corrections, we find that AFB^{SM} = 0.095 +- 0.007. This value is in agreement with the latest D0 measurement [V. M. Abazov et al. (D0 Collaboration), Phys. Rev. D 90, 072011 (2014)] AFB^{D0} = 0.106+- 0.03 and about 1.5 sigma below that of CDF [T. Aaltonen et al. (CDF Collaboration), Phys. Rev. D 87, 092002 (2013)] AFB^{CDF} =0.164 +- 0.047. Our result is derived from a fully differential calculation of the next-to-next-to leading order (NNLO) QCD corrections to inclusive top pair production at hadron colliders and includes - without any approximation - all partonic channels contributing to this process. This is the first complete fully differential calculation in NNLO QCD of a two-to-two scattering process with all coloured partons.

description: The number of people with HIV (PWH) experiencing age-associated comorbidities including those treated with medications and cognitive impairment is increasing. We examined associations between polypharmacy and cognition in older women with HIV (WWH) given their vulnerability to this comorbidity. Cross-sectional analysis capitalizing on Women's Interagency HIV Study data collected between 2014 and 2017. WWH meeting the following criteria were analyzed: age ≥50 years; availability of self-reported non-antiretroviral therapy (ART) medications data; and neuropsychological data. The number of non-ART medications used regularly in the prior 6 months was summed. Polypharmacy was categorized as none/low (0-4), moderate (5-9), or severe (≥10). Multivariable linear regression analyses examined polypharmacy-cognition (T-score) associations in the total sample and among virally suppressed (VS; < 20 copies/mL)-WWH after covariate adjustment for enrollment site, income, depressive symptoms, substance use (smoking, heavy alcohol, marijuana, crack, cocaine, and/or heroin), the Veterans Aging Cohort Study index (indicators of HIV disease and organ system function, hepatitis C virus serostatus), ART use, nadir CD4 count, and specific ART drugs (efavirenz, integrase inhibitors). We included 637 women (median age = 55 years; 72% Black). Ninety-four percent reported ART use in the past 6 months and 75% had HIV RNA <20 copies/mL. Comorbidity prevalence was high (61% hypertension; 26% diabetes). Moderate and severe polypharmacy in WWH were 34% and 24%. In WWH, severe polypharmacy was associated with poorer executive function (p = .007) and processing speed (p = .01). The same pattern of findings remained among VS-WWH. Moderate polypharmacy was not associated with cognition. Moderate and severe polypharmacy were common and associated with poorer executive function and processing speed in WWH. Severe polypharmacy may be a major contributor to the persistence of domain-specific cognitive complications in older WWH above and beyond the conditions that these medications are used to treat.
Nonlocal Damping of Helimagnets in One-Dimensional Interacting Electron Systems

description: We investigate the magnetization relaxation of a one-dimensional helimagnetic system coupled to interacting itinerant electrons. The relaxation is assumed to result from the emission of plasmons, the elementary excitations of the one-dimensional interacting electron system, caused by slow changes of the magnetization profile. This dissipation mechanism leads to a highly nonlocal form of magnetization damping that is strongly dependent on the electron-electron interaction. Forward scattering processes lead to a spatially constant damping kernel, while backscattering processes produce a spatially oscillating contribution. Due to the nonlocal damping, the thermal fluctuations become spatially correlated over the entire system. We estimate the characteristic magnetization relaxation times for magnetic quantum wires and nuclear helimagnets.

Robust Kronecker Product PCA for Spatio-Temporal Covariance Estimation
Creators: name: Greenewald, Kristjan

Publisher: name: arXiv
Year: 2014
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: Kronecker PCA involves the use of a space vs. time Kronecker product decomposition to estimate spatio-temporal covariances. In this work the addition of a sparse correction factor is considered, which corresponds to a model of the covariance as a sum of Kronecker products of low (separation) rank and a sparse matrix. This sparse correction extends the diagonally corrected Kronecker PCA of [Greenewald et al 2013, 2014] to allow for sparse unstructured "outliers" anywhere in the covariance matrix, e.g. arising from variables or correlations that do not fit the Kronecker model well, or from sources such as sensor noise or sensor failure. We introduce a robust PCA-based algorithm to estimate the covariance under this model, extending the rearranged nuclear norm penalized LS Kronecker PCA approaches of [Greenewald et al 2014, Tsiligkaridis et al 2013]. An extension to Toeplitz temporal factors is also provided, producing a parameter reduction for temporally stationary measurement modeling. High dimensional MSE performance bounds are given for these extensions. Finally, the proposed extension of KronPCA is evaluated on both simulated and real data coming from yeast cell cycle experiments. This establishes the practical utility of robust Kronecker PCA in biological and other applications.
