Responsible Scoring Mechanisms Through Function Sampling.

Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Human decision-makers often receive assistance from data-driven algorithmic systems that provide a score for evaluating objects, including individuals. The scores are generated by a function (mechanism) that takes a set of features as input and generates a score.The scoring functions are either machine-learned or human-designed and can be used for different decision purposes such as ranking or classification. Given the potential impact of these scoring mechanisms on individuals' lives and on society, it is important to make sure these scores are computed responsibly. Hence we need tools for responsible scoring mechanism design. In this paper, focusing on linear scoring functions, we highlight the importance of unbiased function sampling and perturbation in the function space for devising such tools. We provide unbiased samplers for the entire function space, as well as a $\theta$-vicinity around a given function. We then illustrate the value of these samplers for designing effective algorithms in three diverse problem scenarios in the context of ranking. Finally, as a fundamental method for designing responsible scoring mechanisms, we propose a novel approach for approximating the construction of the arrangement of hyperplanes. Despite the exponential complexity of an arrangement in the number of dimensions, using function sampling, our algorithm is linear in the number of samples and hyperplanes, and independent of the number of dimensions.

description: The full parameter space of supergravity grand unified theory with $SU(5)$ type $p \rightarrow \barν K$ proton decay is analysed using renormalization group induced electroweak symmetry breaking under the restrictions that the universal scalar mass $m_o$ and gluino mass are $\leq 1$ TeV (no extreme fine tuning) and the Higgs triplet mass obeys $M_{H_3}/M_G < 10$. Future proton decay experiments at SuperKamiokande or ICARUS can reach a sensitivity for the $\barν K$ mode of $(2-5) \times 10^{33}$ yr allowing a number of predictions concerning the SUSY mass spectrum. Thus either the $p \rightarrow\barν K$ decay mode will be seen at these experiments or a chargino of mass $m_{\tilde{W}} < 100$ GeV will exist and hence be observable at LEP2. Further, if $(p \rightarrow \barν K) > 1.5 \times 10^{33}$ yr, then either the light Higgs has mass $m_h \leq 95$ GeV or $m_{\tilde{W}} \leq 100$ GeV i.e. either the light Higgs or the light chargino (or both) would be observable at LEP2. Thus, the combination of future accelerator and future underground experiments allow for strong experimental tests of this theory.

description: Investigation of the coenzyme binding site of lactate dehydrogenase was approached by using coenzyme analogs. Inhibition studies of this enzyme using n-alkylphosphates as coenzyme analogs were performed with a fluorometric method. The results showed that all of the n-alkylphosphates were competitive inhibitors with respect to NAD+.

The n-alkyl-ADPs were synthesized from AMP and dicycloheaylammonium salts of n-alkylphosphates. The synthetic compounds were subjected to NMR spectroscopic studies, thin layer chromatography and determination of the ratio of adenosine moiety to phosphate groups. The results indicated that the synthetic compounds were n-alkyl-ADPs.

These synthetic compounds were used as coenzyme analogs in inhibition studies of lactate dehydrogenase. The results showed that all were competitive inhibitors. Inhibitor dissociation constants of both series of inhibitors were calculated from the experimental data. The inhibitor dissociation constants of all of the n-alkyl-ADPs were at least ten times smaller than those of their corresponding n-alkylphosphates. This indicated that the stronger binding effect is due to AMP moiety.

description: The universal Tan relations connect a variety of microscopic features of many-body quantum systems with two-body contact interactions to a single quantity, called the contact. The latter has become pivotal in the description of quantum gases.We provide a complete characterization of the Tan contact of the harmonically trapped Lieb-Liniger gas for arbitrary interactions and temperature.Combining thermal Bethe ansatz, local-density approximation, and exact quantum Monte Carlo calculations,we show that the contact is a universal function of only two scaling parameters, and determine the scaling function.We find that the temperature dependence of the contact, or equivalently the interaction dependence of the entropy, displays a maximum. The presence of this maximum provides an unequivocal signature of the crossover to the fermionized regime and it is accessible in current experiments.

description: The purpose of this chapter is to identify the critical issues underlying the construct of organizational effectiveness (OE). The basic assumption is that understanding organizational effectiveness is a precondition to dealing with problems in organizational assessment. The concept of effectiveness is complex and value-laden. There is no simple path to construct specification. Our objective therefore is to identify the critical issues ans some approaches to their resolution.

description: We construct exact nonstatic nonhomogeneous spherically symmetric solutions in the theory of gravity with a scalar field possessing the exponential potential. The solution of particular interest corresponds to the scalar field with negative kinetic energy, i.e. a ghost, and represents two asymptotically homogeneous spatially flat universes connected by a throat. We interpret this solution as a wormhole in cosmological setting. Both the universes and the wormhole throat are simultaneously expanding with acceleration. The character of expansion qualitatively depends on the wormhole's mass $m$. For $m=0$ the expansion goes exponentially, so that the corresponding spacetime configuration represents two de Sitter universes joining by the throat. For $m>0$ the expansion has the power character, so that one has the inflating wormhole connecting two homogeneous spatially flat universes expanding according to the power law into the final singularity. The stability analysis of the non-static wormholes reveals their instability against linear spherically symmetric perturbations.

description: Second generation sequencing technologies are being increasingly used for genetic association studies, where the main research interest is to identify sets of genetic variants that contribute to various phenotype. The phenotype can be univariate disease status, multivariate responses and even high-dimensional outcomes. Considering the genotype and phenotype as two complex objects, this also poses a general statistical problem of testing association between complex objects. We here proposed a similarity-based test, generalized similarity U (GSU), that can test the association between complex objects. We first studied the theoretical properties of the test in a general setting and then focused on the application of the test to sequencing association studies. Based on theoretical analysis, we proposed to use Laplacian kernel based similarity for GSU to boost power and enhance robustness. Through simulation, we found that GSU did have advantages over existing methods in terms of power and robustness. We further performed a whole genome sequencing (WGS) scan for Alzherimer Disease Neuroimaging Initiative (ADNI) data, identifying three genes, APOE, APOC1 and TOMM40, associated with imaging phenotype. We developed a C++ package for analysis of whole genome sequencing data using GSU. The source codes can be downloaded at https://github.com/changshuaiwei/gsu.

description: We study finite size effects in superconducting metallic grains and determine the BCS order parameter and the low energy excitation spectrum in terms of size, and shape of the grain. Our approach combines the BCS self-consistency condition, a semiclassical expansion for the spectral density and interaction matrix elements, and corrections to the BCS mean-field. In chaotic grains mesoscopic fluctuations of the matrix elements lead to a smooth dependence of the order parameter on the excitation energy. In the integrable case we observe shell effects when e.g. a small change in the electron number leads to large changes in the energy gap.

The impact of rise time discrimination, language ability, memory, and attention on speech recognition in noise
Creators: name: Luengtaweekul, Ponsuang

Year: 2024
Subjects: classificationCode: 420102
subject: Audiology

description:   
Background: The ability to perceive and recognise speech in background noise is crucial for effective communication in everyday life. However, what factors contribute to this ability is not well understood. Several studies have highlighted that cognitive factors such as attention and memory are relevant for speech recognition in noise. The role of auditory processing is less well-established, however. Auditory processing is not a unitary skill and encompasses several sub-skills that target binaural processing and analysis of spectral and temporal cues. This study consequently aimed to investigate the importance of auditory processing skills, specifically the perception of rise times and amplitude modulation, cognitive skills, such as working memory and selective attention, and language ability on speech recognition in noise and to determine which of these abilities predicts speech recognition in noise.
Participants and Methods: Forty-eight young normal-hearing participants (aged 19.3 to 35.6 years) participated in the current research. They all underwent the measures of auditory processing skills, including the perception of rise time and amplitude modulation, working memory, selective attention, and language ability. The dependent variable was the sentence recognition score in noise as measured by The Test of Listening Difficulties – Universal (ToLD-U). Predictor variables included the scores on rise time discrimination tasks, Parsing Syllable Envelopes (ParSE) test, backward digit Span, Test of Everyday Attention, and AudiCloze. Correlation and regression analysis were performed.
Results: The results of correlation analysis showed that only the AudiCloze, a measure of language ability, was significantly correlated with the ToLD-U score, r(46) = -.59, p < .001. There were no significant correlations between ToLD-U and other measures. However, the correlation with selective attention was close to significant, r(46) = -.27, p = .063. Regression analysis showed that AudiCloze and selective attention scores explained 58% of the variance (R² = 0.58, F(2, 45) = 30.9, p < .001) in speech recognition in noise performance on ToLD-U.
Conclusion: The findings are consistent with previous literature that language and selective attention are significant predictors of speech recognition in noise in young normal-hearing adults. The chosen auditory processing skills were not associated with speech recognition skills, at least for young adults. It is possible that the role of auditory processing is more relevant in children when language and attention skills are still maturing. To assess this hypothesis, future studies will evaluate the association between auditory processing skills and speech recognition in noise in school-aged children.

description: Studies of the most luminous quasars at high redshift directly probe the evolution of the most massive black holes in the early Universe and their connection to massive galaxy formation. However, extremely luminous quasars at high redshift are very rare objects. Only wide area surveys have a chance to constrain their population. The Sloan Digital Sky Survey (SDSS) has so far provided the most widely adopted measurements of the quasar luminosity function (QLF) at $z>3$. However, a careful re-examination of the SDSS quasar sample revealed that the SDSS quasar selection is in fact missing a significant fraction of $z\gtrsim3$ quasars at the brightest end. We have identified the purely optical color selection of SDSS, where quasars at these redshifts are strongly contaminated by late-type dwarfs, and the spectroscopic incompleteness of the SDSS footprint as the main reasons. Therefore we have designed the Extremely Luminous Quasar Survey (ELQS), based on a novel near-infrared JKW2 color cut using WISE AllWISE and 2MASS all-sky photometry, to yield high completeness for very bright ($m_{\rm{i}} < 18.0$) quasars in the redshift range of $3.0\leq z\leq5.0$. It effectively uses random forest machine-learning algorithms on SDSS and WISE photometry for quasar-star classification and photometric redshift estimation. The ELQS will spectroscopically follow-up $\sim 230$ new quasar candidates in an area of $\sim12000\,\rm{deg}^2$ in the SDSS footprint, to obtain a well-defined and complete quasars sample for an accurate measurement of the bright-end quasar luminosity function at $3.0\leq z\leq5.0$. In this paper we present the quasar selection algorithm and the quasar candidate catalog.

description: Propagation in equilibrium models of search unemployment is significantly altered when vacancy costs require some external financing on frictional credit markets. The easing of financing constraints during an expansion reduces the opportunity cost of resources allocated to job creation, raising the elasticity of market tightness through (i) a cost channel, increasing incentive to recruit for a given benefit from a new hire; (ii) a wage channel, whereby an improved bargaining position of firms limits the upward pressure of market tightness on wages. The calibrated model can match the volatility and persistence of market tightness observed in the data.

description: Traditional methods for assessing illness severity and predicting in-hospital mortality among critically ill patients require time-consuming, error-prone calculations using static variable thresholds. These methods do not capitalize on the emerging availability of streaming electronic health record data or capture time-sensitive individual physiological patterns, a critical task in the intensive care unit. We propose a novel acuity score framework (DeepSOFA) that leverages temporal measurements and interpretable deep learning models to assess illness severity at any point during an ICU stay. We compare DeepSOFA with SOFA (Sequential Organ Failure Assessment) baseline models using the same model inputs and find that at any point during an ICU admission, DeepSOFA yields significantly more accurate predictions of in-hospital mortality. A DeepSOFA model developed in a public database and validated in a single institutional cohort had a mean AUC for the entire ICU stay of 0.90 (95% CI 0.90-0.91) compared with baseline SOFA models with mean AUC 0.79 (95% CI 0.79-0.80) and 0.85 (95% CI 0.85-0.86). Deep models are well-suited to identify ICU patients in need of life-saving interventions prior to the occurrence of an unexpected adverse event and inform shared decision-making processes among patients, providers, and families regarding goals of care and optimal resource utilization.

description: We have investigated the stability limits of small spin-polarized clusters consisting of up to ten spin-polarized tritium T$\downarrow$ atoms and the mixtures of T$\downarrow$ with spin-polarized deuterium D$\downarrow$ and hydrogen H$\downarrow$ atoms. All of our calculations have been performed using the variational and diffusion Monte Carlo methods. For clusters with D$\downarrow$ atoms, the released node procedure is used in cases where the wave function has nodes. In addition to the energy, we have also calculated the structure of small clusters using unbiased estimators. Results obtained for pure T$\downarrow$ clusters are in good accordance with previous calculations, confirming that the trimer is the smallest spin-polarized tritium cluster. Our results show that mixed T$\downarrow$-H$\downarrow$ clusters having up to ten atoms are unstable and that it takes at least three tritium atoms to bind one, two or three D$\downarrow$ atoms. Among all the considered clusters, we have found no other Borromean states except the ground state of the T$\downarrow$ trimer.

description: This paper is a demonstration of how the WKB approximation can be used to help solve the linearised 3D MHD equations. Using Charpit's Method and a Runge-Kutta numerical scheme, we have demonstrated this technique for a potential 3D magnetic null point, ${\bf{B}}=(x,εy -(ε+1)z)$. Under our cold plasma assumption, we have considered two types of wave propagation: fast magnetoacoustic and Alfvén waves. We find that the fast magnetoacoustic wave experiences refraction towards the magnetic null point, and that the effect of this refraction depends upon the Alfvén speed profile. The wave, and thus the wave energy, accumulates at the null point. We have found that current build up is exponential and the exponent is dependent upon $ε$. Thus, for the fast wave there is preferential heating at the null point. For the Alfvén wave, we find that the wave propagates along the fieldlines. For an Alfvén wave generated along the fan-plane, the wave accumulates along the spine. For an Alfvén wave generated across the spine, the value of $ε$ determines where the wave accumulation will occur: fan-plane ($ε=1$), along the $x-$axis ($01$). We have shown analytically that currents build up exponentially, leading to preferential heating in these areas. The work described here highlights the importance of understanding the magnetic topology of the coronal magnetic field for the location of wave heating.

description: We propose a new mechanism of (geometric) moduli stabilisation in type IIB/F-theory four-dimensional compactifications on Calabi-Yau manifolds, in the presence of 7-branes, that does not rely on non-perturbative effects. Complex structure moduli and the axion-dilaton system are stabilised in the standard way, without breaking supersymmetry, using 3-form internal fluxes. Kähler class moduli stabilisation utilises perturbative string loop corrections, together with internal magnetic fields along the D7-branes world-volume leading to Fayet-Iliopoulos D-terms in the effective supergravity action. The main ingredient that makes the stabilisation possible at a de Sitter vacuum is the logarithmic dependence of the string loop corrections in the large two-dimensional transverse volume limit of the 7-branes.

description: The interaction between charged particles and the vacuum fluctuations of the electromagnetic field induces decoherence, and therefore affects the contrast of fringes in an interference experiment. In this article we show that if a double slit experiment is performed near a conducting grating, the fringe visibility is reduced. We find that the reduction of contrast is proportional to the number of grooves in the conducting surface, and that for realistic values of the parameters it could be large enough to be observed. The effect can be understood in terms of the Smith-Purcell radiation produced by the surface currents induced in the conductor.

description: Artificial Intelligence is a rapidly expanding field within computer science that encompasses the emulation of human intelligence by machines. Machine learning and deep learning – two primary data-driven pattern analysis approaches under the umbrella of artificial intelligence – has created considerable interest in the last few decades. The evolution of technology has resulted in a substantial amount of artificial intelligence research on ophthalmic and neurodegenerative disease diagnosis using retinal images. Various artificial intelligence-based techniques have been used for diagnostic purposes, including traditional machine learning, deep learning, and their combinations. Presented here is a review of the literature covering the last 10 years on this topic, discussing the use of artificial intelligence in analysing data from different modalities and their combinations for the diagnosis of glaucoma and neurodegenerative diseases. The performance of published artificial intelligence methods varies due to several factors, yet the results suggest that such methods can potentially facilitate clinical diagnosis. Generally, the accuracy of artificial intelligence-assisted diagnosis ranges from 67–98%, and the area under the sensitivity-specificity curve (AUC) ranges from 0.71–0.98, which outperforms typical human performance of 71.5% accuracy and 0.86 area under the curve. This indicates that artificial intelligence-based tools can provide clinicians with useful information that would assist in providing improved diagnosis. The review suggests that there is room for improvement of existing artificial intelligence-based models using retinal imaging modalities before they are incorporated into clinical practice.

description: We consider a dynamic moral hazard economy inhabited by a planner and a population of privately informed agents. We assume that the planner and the agents share the same discount factor, but that the planner cannot commit. We show that optimal allocations in such settings solve the problems of committed planners who discount the future less heavily than agents. Thus, we provide micro- foundations for dynamic moral hazard models that assume a societal discount factor in excess of the private one. We extend the analysis to allocations that are reconsideration-proof in the sense of Kocherlakota (1996). We show that these allocations solve the choice problem of a committed planner with a unit discount factor.

description: We explore the possibility of unification of gauge couplings near the Planck scale in models of extended technicolor. We observe that models of the form G X SU(3)_c X SU(2)_L X U(1)_Y cannot be realized, due to the presence of massless neutral Goldstone bosons (axions) and light charged pseudo-Goldstone bosons; thus, unification of the known forces near the Planck scale cannot be achieved. The next simplest possibility, G X SU(4)_{PS} X SU(2)_L X U(1)_{T_{3R}}, cannot lead to unification of the Pati-Salam and weak gauge groups near the Planck scale. However, superstring theory provides relations between couplings at the Planck scale without the need for an underlying grand-unified gauge group, which allows unification of the SU(4)$_{PS}$ and SU(2)$_L$ couplings.

description: In this paper we suggest an analytic model, and derive simple formulas, for the beam dynamics in a wakefield structure of arbitrary cross-section. The results could be applied to estimate an upper limit of the projected beam size in devices such as the dechirper and the wakefield streaking device. The suggested formalism is also applicable to the case when slices of the beam are distributed along an arbitrary line in 3D.

description: The analysis of intelligence information invariably involves both cognitive and social processes. At core, analysis is a cognitive activity. Although intelligence analysts often draw both on technological aids and on input from others, ultimately it is the human brain that organizes and interprets data to generate an assessment or prediction. A great deal of research has been conducted to identify both the cognitive biases that can compromise the validity of analytic conclusions and the heuristics that can help analysts do their work efficiently and well (see, for example, the well-known book by Richards Heuer [1999] on the psychology of intelligence analysis, research by Gerd Gigerenzer and his colleagues [1999] on "fast and frugal" heuristics, and the other chapters in this volume).

description: Multiplayer computer games play a big role in the ever-growing entertainment industry. Being competitive in this industry means releasing the best possible software, and reliability is a key feature to win the market. Computer games are also actively used to simulate different robotic systems where reliability is even more important, and potentially critical. Traditional software testing approaches can check a subset of all the possible program executions, and they can never guarantee complete absence of errors in the source code. On the other hand, during more than twenty years, Model Checking has demonstrated to be a powerful instrument for formal verification of large hardware and software components. In this paper, we contribute with a novel approach to formally verify computer games. We propose a method of model construction that starts from a computer game description and utilizes Model Checking technique. We apply the method on a case study: the game Penguin Clash. Finally, an approach to game model reduction (and its implementation) is introduced in order to address the state explosion problem.

description: Signal reconstruction problem (SRP) is an important optimization problem where the objective is to identify a solution to an underdetermined system of linear equations that is closest to a given prior. It has a substantial number of applications in diverse areas, such as network traffic engineering, medical image reconstruction, acoustics, astronomy, and many more. Unfortunately, most of the common approaches for solving SRP do not scale to large problem sizes. We propose a novel and scalable algorithm for solving this critical problem. Specifically, we make four major contributions. First, we propose a dual formulation of the problem and develop the DIRECT algorithm that is significantly more efficient than the state of the art. Second, we show how adapting database techniques developed for scalable similarity joins provides a substantial speedup over DIRECT. Third, we describe several practical techniques that allow our algorithm to scale-on a single machine-to settings that are orders of magnitude larger than previously studied. Finally, we use the database techniques of materialization and reuse to extend our result to dynamic settings where the input to the SRP changes. Extensive experiments on real-world and synthetic data confirm the efficiency, effectiveness, and scalability of our proposal.

description: We present a general framework for determining the number of solutions of constraint satisfaction problems (CSPs) with a high precision. Our first strategy uses additional binary variables for the CSP, and applies an XOR or parity constraint based method introduced previously for Boolean satisfiability (SAT) problems. In the CSP framework, in addition to the naive individual filtering of XOR constraints used in SAT, we are able to apply a global domain filtering algorithm by viewing these constraints as a collection of linear equalities over the field of two elements. Our most promising strategy extends this approach further to larger domains, and applies the so-called generalized XOR constraints directly to CSP variables. This allows us to reap the benefits of the compact and structured representation that CSPs offer. We demonstrate the effectiveness of our counting framework through experimental comparisons with the solution enumeration approach (which, we believe, is the current best generic solution counting method for CSPs), and with solution counting in the context of SAT and integer programming.

description: We present measurements of the frequency and electric field dependent conductivity of single walled carbon nanotube(SWCNT) networks of various densities. The ac conductivity as a function of frequency is consistent with the extended pair approximation model and increases with frequency above an onset frequency $ω_0$ which varies over seven decades with a range of film thickness from sub-monolayer to 200 nm. The nonlinear electric field-dependent DC conductivity shows strong dependence on film thickness as well. Measurement of the electric field dependence of the resistance R(E) allows for the determination of a length scale $L_{E}$ possibly characterizing the distance between tube contacts, which is found to systematically decrease with increasing film thickness. The onset frequency $ω_0$ of ac conductivity and the length scale $L_{E}$ of SWCNT networks are found to be correlated, and a physically reasonable empirical formula relating them has been proposed. Such studies will help the understanding of transport properties and benefit the applications of this material system.

description: Many networks have nodes located in physical space, with links more common between closely spaced pairs of nodes. For example, the nodes could be wireless devices and links communication channels in a wireless mesh network. We describe recent work involving such networks, considering effects due to the geometry (convex,non-convex, and fractal), node distribution, distance-dependent link probability, mobility, directivity and interference.

description: Skeletal muscles are considered one of the most dynamic tissues due to their capabilities of remodelling, repair, and regeneration attributed to their unique population of stem cells known as muscle stem cells (MuSCs). Mitochondrial function, maintenance, and remodelling has been linked with the ability of the MuSCs to maintain quiescence, undergo self-renewal, and differentiate in order to regenerate muscle. Subsequently, mechanisms affecting mitochondrial properties in MuSCs, including mitophagy, are suggested to play an important role. To determine the role of mitophagy in MuSC behavior, we developed a mouse model harboring a conditional MuSC specific inactivation of the key mitophagy gene Parkin. In vitro single myofiber experiments showed that Parkin deficiency triggered premature expression of activation and differentiation MuSC markers and lowered the proportion of quiescent cells indicating premature activation/commitment at the expense of the quiescent/self-renewing MuSC pool. Furthermore, cell cycle re-entry and proliferation were impaired in absence of Parkin, as evidenced by a reduction of MuSC cluster size, and the number of Ki67 (proliferation marker) expressing cells. Moreover, immunofluorescent experiments in the Tibialis Anterior (TA) muscle form cardiotoxin injured mice showed reduction in the Pax7+ and Ki67+ MuSCs at 7- and 14- days post injury indicating defects in the MuSC self-renewal and proliferation during muscle regeneration. The injured muscle also had a significant reduction in fiber size post injury indicating improper muscle regeneration and a defect in the regenerative potential. Furthermore, post-injury the Parkin deficient muscle also had a significant decrease in the number of Pax7+ self-renewing MuSCs signifying depletion of the MuSC pool. Together, our data suggests that manipulation of Parkin-mediated mitophagy alters muscle stem cell fate and lineage progression causing an imbalance in MuSC self-renewal and proliferation. Alterations in Parkin mediated mitophagy also impairs muscle regeneration and promotes the activation and commitment of MuSCs at the expense of MuSC self-renewal.
