description: The ensemble of deep neural networks has been shown, both theoretically and empirically, to improve generalization accuracy on the unseen test set. However, the high training cost hinders its efficiency since we need a sufficient number of base models and each one in the ensemble has to be separately trained. Lots of methods are proposed to tackle this problem, and most of them are based on the feature that a pre-trained network can transfer its knowledge to the next base model and then accelerate the training process. However, these methods suffer a severe problem that all of them transfer knowledge without selection and thus lead to low diversity. As the effect of ensemble learning is more pronounced if ensemble members are accurate and diverse, we propose a method named Efficient Diversity-Driven Ensemble (EDDE) to address both the diversity and the efficiency of an ensemble. To accelerate the training process, we propose a novel knowledge transfer method which can selectively transfer the previous generic knowledge. To enhance diversity, we first propose a new diversity measure, then use it to define a diversity-driven loss function for optimization. At last, we adopt a Boosting-based framework to combine the above operations, such a method can also further improve diversity. We evaluate EDDE on Computer Vision (CV) and Natural Language Processing (NLP) tasks. Compared with other well-known ensemble methods, EDDE can get highest ensemble accuracy with the lowest training cost, which means it is efficient in the ensemble of neural networks.

Ni-based catalysts

description: Due to environmental concerns, dry reforming of methane (DRM), which converts two major greenhouse gases (CH₄ and CO₂) into syngas (H₂ and CO), has gained increasing attention in recent years. This research aims to contribute to the development of a commercially viable Ni catalyst for DRM. Firstly, a study on the oxide-phase origin of the Ni metal in Ni/Al₂O₃ catalysts was conducted and published. Different Ni metal sources, such as NiO or NiAl₂O₄, influenced important properties of the fully reduced Ni/Al₂O₃ catalysts, including Ni particle size, dispersion, and metal-support interactions. Notably, the Ni/Al₂O₃ catalyst obtained from the NiAl₂O₄ phase showed the most active, selective, and stable performance with limited carbon deposits buildup. To investigate carbonaceous species on the spent Ni/Al₂O₃ catalysts, the catalytic behavior of the Ni/Al₂O₃ catalyst for carbon formation from CH₄ decomposition and its removal by the reverse Boudouard reaction was examined via sequential temperature-programmed experiments. By carefully considering both the location and characteristics of carbon deposits formed on the spent Ni/Al₂O₃ catalyst, it was concluded that carbons located on the Al₂O₃ support are challenging to remove by CO₂ regardless of their nature, indicating the importance of support activity in reducing carbon deposits. This study demonstrated the efficacy of the incorporation of cesium (Cs) into the Al₂O₃ support. Finally, a physical mixture of Ru/Al₂O₃ with Ni/Al₂O₃ obtained from the NiAl₂O₄ phase was suggested as a highly active, durable, and cost-effective catalyst for DRM. By using a NiAl₂O₄ phase and conducting in-situ reduction by CH₄ under reaction conditions, the formation of metallic Ni sites was limited depending on the reaction temperatures. As a result, this mixed catalyst showed higher performance for DRM than a single Ru catalyst, with mild carbon deposits, taking advantage of improved cost-effectiveness. Furthermore, the presence of a Ni catalyst compensated for the loss of activity of a Ru catalyst caused by sintering at high temperature.

description: Advances in wireless networking and content delivery systems are enabling new challenging provisioning scenarios where a growing number of users access multimedia services, e.g., audio/video streaming, while moving among different points of attachment to the Internet, possibly with different connectivity technologies, e.g., Wi-Fi, Bluetooth, and cellular 3G. That calls for novel middlewares capable of dynamically personalizing service provisioning to the characteristics of client environments, in particular to
discontinuities in wireless resource availability due to handoffs. This dissertation proposes a novel middleware solution, called MUM, that performs effective and context-aware handoff management to transparently avoid service interruptions during both horizontal and vertical handoffs. To achieve the goal, MUM exploits the full visibility of wireless connections available in client localities and their handoff implementations (handoff awareness), of service quality requirements and handoff-related quality degradations (QoS awareness), and of network topology and resources available in current/future localities (location awareness). The design and implementation of the all main MUM components along with extensive on the field trials of the realized middleware architecture confirmed the validity of the proposed full
context-aware handoff management approach. In particular, the reported experimental results demonstrate that MUM can effectively maintain service continuity for a wide range of different multimedia services by exploiting handoff prediction mechanisms, adaptive buffering and pre-fetching techniques, and proactive re-addressing/re-binding.

description: {\bf Purpose}: Manipulation of the radio-sensitivity of the nucleotide-base driven by the spin blockade mechanism of diffusive free radicals against ionizing radiation. {\bf Materials and methods}: We theoretically propose a mechanism which uses the simultaneous application of circularly polarized light and an external magnetic field to control the polarization of the free radicals and create S=1 electron-hole spin excitations (excitons) on nucleotide-base. We deploy an ab-initio molecular dynamics model to calculate the characteristic parameters of the light needed for optical transitions. {\bf Results}: As a specific example, we present the numerical results calculated for a Guanine, in the presence of an OH free radical. To increase the radio-resistivity of this system, a blue light source for the optical pumping and induction of excitons on guanine can be used. {\bf Conclusions}: The effect of spin-injection on the formation of a free energy barrier in diffusion controlled chemical reaction pathways leads to the control of radiation-induced base damage. The proposed method allows us to manipulate and partially suppress the damage induced by ionizing radiation.

description: This thesis is divided in two parts. Each one of them is devoted to the study of a semilinear elliptic equation arising as a model to understand a phenomenon that lies in the interplay between physics and geometry. In the first part, we provide an approximation to the Euclidean-isoperimetric problem via the Allen-Cahn energy functional. For non-degenerate double well potentials, we prove sharp quantitative stability inequalities of quadratic type which are uniform in the length scale of the phase transitions. We also derive a rigidity theorem for critical points analogous to the classical Alexandrov's theorem for constant mean curvature boundaries. In the second part, we establish regularity and uniqueness results for Grad-Mercier type equations that arises in the context of plasma physics. We show that solutions of this problem develop naturally a dead core, which corresponds to the set where the solutions become identically equal to its maximum. We prove sharp regularity and non-degeneracy bounds for the solution when the domain exhibit certain types of symmetry, e.g., radial or axial symmetry. We also prove some initial regularity estimates for the free boundary associated with the dead core. Our approach is non-variational, only recurring to the maximum principle, which allows us to carry out our arguments for a large spectrum of elliptic (nonlinear) operators.

description: THE CRICKET is a feature-length family comedy screenplay. It follows the journey of CECIL, a hopeful and affectionate pet store cricket in the “Live Reptile Food” section of the store. Cecil dreams of being adopted like all the cute puppies and kittens on the other side of the store (but he is, in fact, in the store to be sold as food for lizards). The pet store manager’s cat FLUFFY rules the store with an iron fist, constantly reminding the animals of their place in the food chain and the value that humans assign them. Cecil is at the bottom of both scales, but steadfastly believes there’s a family out there that will want to adopt him. One day, a little girl named AGNES falls in love with him on a shopping trip to the pet store. She promises to care for him and love him forever, but her mom pulls her away. Cecil goes after her, dragging along his best friend – a mealworm named MEL, who wishes Cecil would realize that he already has everything he needs with his animal friendships. But Mel adores Cecil and goes along with the plan. Along the way, Cecil meets new friends, including a feeder rat named OPHELIA, who is a classically trained actor with dreams of joining a Shakespeare troupe, and a sickly dog named DEWEY, who just wants to be part of a group. Cecil experiences scary and wonderful life in the wild as he and his friends journey to Agnes’s house. All the while, Fluffy pursues them – no one escapes their place in the system! No one escapes the food chain! Plus, tensions grow among Cecil and his friends as his friends start loving life in the wild and questioning Cecil’s ongoing desire to be a pet. Wouldn’t it be better to be free? To not be owned by anyone? But Cecil is single-minded in his desire to be a pet – to be considered worthy and wanted. After a series of close calls, Cecil and his friends make it to Agnes’s house. She is delighted and instantly takes him in, but her mean older brother kidnaps Cecil to feed to his pet bearded dragon. Meanwhile, Cecil’s friends also find themselves in peril thanks to the human world. Cecil finally realizes that his true destiny is not to be a pet. His destiny is to rescue and value his friends and be a free independent cricket who owns himself. He escapes and reconciles with his friends, who then rush to the pet store to free all the animals. In the end, Cecil and Mel decide to be roommates, living in the wild together as best friends who own themselves.

description: In order to investigate whether galaxy structures are compatible with the predictions of the standard LCDM cosmology, we focus here on the analysis of several simple and basic statistical properties of the galaxy density field. Namely, we test whether, on large enough scales (i.e., r>10 Mpc/h), this is self-averaging, uniform and characterized by a Gaussian probability density function of fluctuations. These are three different and clear predictions of the LCDM cosmology which are fulfilled in mock galaxy catalogs generated from cosmological N-body simulations representing this model. We consider some simple statistical measurements able to tests these properties in a finite sample. We discuss that the analysis of several samples of the Two Degree Field Galaxy Redshift Survey and of the Sloan Digital Sky Survey show that galaxy structures are non self-averaging and inhomogeneous on scales of ~100 Mpc/h, and are thus intrinsically different from LCDM model predictions. Correspondingly the probability density function of fluctuations shows a "fat tail" and it is thus different from the Gaussian prediction. Finally we discuss other recent observations which are odds with LCDM predictions and which are, at least theoretically, compatible with the highly inhomogeneous nature of galaxy distribution. We point out that inhomogeneous structures can be fully compatible with statistical isotropy and homogeneity, and thus with a relaxed version of the Cosmological Principle.

description: In the hyper-polarized environment of modern U.S. elections, how can campaigns persuade voters? While persuasion has been considered a key part of a functioning democracy (Berelson et al, 2950, Key 1966), with stronger party attachments, how many individual voters are movable? Furter, is it worth it for campaigns to focus on persuasion when identifying and mobilizing like-minded partisans seems so much easier, cost effective, and efficient (Panagopoulos 2021)? This dissertation is focused on what persuasion might look like in the context of contemporary American electoral politics. First, I introduce a new theory of voting behavior that combines issue ownership and theories of cross-pressures. I argue that these voters are persuadable, and that campaigns can target them to increase partisan defection. Second, I find that about seven percent of Americans are cross-pressured in this way, and that they are more likely to defect on Election Day. Third, I utilize a survey experiment to explore how candidates can campaign on owned issues to increase their electoral vote share. Finally, I explore the findings from a field experiment conducted in Texas during the 2022 Gubernatorial Election.

description: As of August 2022, the United Nations (UN) Refugee Agency confirmed that there are 6.8 million displaced Venezuelans worldwide. This makes Venezuelans the largest group of refugees and crisis migrants worldwide, tying with Ukraine and surpassing Syria for the first time (Alvarez, 2022). Even though the number of Venezuelans in the U.S. continues to grow, their migration and acculturation experiences are not well understood. Once they arrive in the U.S., Venezuelan migrants continue to face challenges and stress, such as adapting to a new culture, language, system, and overall environment, which exacerbates the stress and trauma that this group of migrants brings with them. The present study examined the experiences of Venezuelan crisis immigrant parents. Using an explanatory sequential mixed-method design, the present study was guided by two objectives. The first objective was to quantitatively examine the relationships among cultural stress, cultural adaptation, psychological symptoms (anxiety and depression), and how this relationship is impacted by co-ethnic density and Latino/a density. The second objective was to qualitatively examine how access to cultural elements (such as food, cultural traditions, and customs, support from other Venezuelans, etc.) in their environment may contextualize the relationship between cultural stress and psychological symptoms. Quantitative results indicated that Latino/a density had a marginal moderating effect on the relationship between psychological adaptation and depressive symptoms. Specifically, for participants in neighborhoods with a greater percentage of Latino/a residents, psychological adaptation was less strongly and negatively related to depressive symptoms. Regarding the qualitative results, four themes emerged. One of the most important findings highlighted that the most influential aspect of adaptation is being able to cover basic needs.
Model complexity and risk aversion in decision analysis

description: Models are often formulated to aid in decision-making. However, the details included or excluded are often determined with minimal examination of the effects. There is a tendency to make models more complex than merited. Yet, decision makers’ risk preferences are often ignored without considering the effect on recommendations. Additionally, modelers do not always understand the difference between preferences toward deterministic outcomes and risk preferences or the impact of modeling conflicting risk and deterministic preferences together in a single component. In this paper, I investigate the relationship between complexity and accuracy, using COVID-19 forecasting as a case study. I find our simple model is comparable in accuracy to highly publicized models, generating among the best-calibrated forecasts. This may be surprising, given the complexity of many high-profile models supported by large teams. However, it is consistent with research suggesting simple models perform very well in a variety of settings. Although utility functions are a fundamental component of decision analysis, they can assume many forms. For small decisions, the choice might not change the decision. But it can greatly affect recommendations for large decisions. There are qualitative recommendations on which functional form to use. But there is no quantitative recommendation relating size of uncertainties to choice of utility function. By maximizing error in certain equivalents when using different utility functions, this paper provides guidance into when to use different utility functions. Although decision makers should be approximately risk neutral for small problems, they are often “risk averse.” Rabin and Thaler showed utility functions modeling small-scale risk aversion result in absurd risk aversion for large uncertainties. They explain small-scale risk aversion is due to loss aversion, where pain from losses exceeds benefit from gains. But preferences for deterministic losses and gains is a deterministic preference and is not equivalent to risk preference. They argue loss aversion caused the observed behavior, yet modelled deterministic and risk preferences in a single factor. In this paper, I show modeling risk and deterministic preference separately can resolve Rabin’s Paradox, underscoring the need to explicitly model both when deterministic preferences can influence decision making or conflict with risk preferences.

The total chromatic number $χ"(G)$ of $G$ is the smallest integer $k$ such that $G$ has a total $k$-coloring. In the paper, it is proved that for any $K_5$-minor-free graph $G$, $χ''(G)\leq Δ(G)+2$ if $Δ(G)\geq 7$. Moreover, $χ"(G)=Δ(G)+1$ if $Δ(G)\geq 10$.
Doing obstetrics : the organization of work routines in a maternity service
Creators: name: Ford, James Ellsworth
Publisher: name: University of British Columbia
Year: 2010

description: Despite popular and professional concerns with childbirth and prenatal care there are few empirical studies of behavior in hospitals where these events typically occur. The problem set for the study reported here was to observe behavior in the maternity department of a hospital and to provide a theoretical description of what was observed in terms relevant to sociologists' interest in the social organization of work routines of professional staff members serving a lay client population. The thesis is thus a description of medical staff members' work routines, with an analytic interest in how that relates to features of work routines of service occupations in general. Specifically, the study reports upon the ways lay patients may differ from professional medical staff members in their perspectives on prenatal care and childbirth and how staff members see these divergences as often resulting in organizational problems when they try to provide care which is "complete, " efficient and expeditious. Further, the study describes how staff members develop interactional (and other) methods for managing patients, especially those who adhere to these nonmedical perspectives, so as to cope with such practical pressures as the need to schedule patients and their demands, provide a visibly competent performance for superiors, peers and patients, and prepare the patient for efficient and expeditious processing at subsequent organizational stages. It is asserted that these practical pressures (termed demand characteristics) are features commonly found in work routines of service occupations in general. Finally, it is argued that an ethnographic study of work routines of professional staff members of service institutions, e_. g., hospitals, may be necessary to explain adequately features of apparently natural or biological events, such as childbirth, that occur within them.

description: This thesis concerns the development of neural network models for understanding magnetism in quantum many body systems. Chapter 1 discusses the quantum many body problem and the outstanding difficulty of modeling many-body physics. Chapter 2 introduces spin models, frustrated magnetism, quantum spin liquids, and some of the numerical approaches used to solve these problems. Chapter 3 describes the neural quantum state approach, a novel method for encoding the wavefunction of a quantum many body system. Chapter 4 provides some background material on group theory, lattice symmetry groups, and classical and quantum orders. These are techniques that, in combination with symmetry-resolved neural networks, can be used to provide novel analysis on quantum spin liquids and other strongly-correlated quantum many body phases. Chapter 5 introduces the group convolutional neural network (GCNN) for building symmetry-resolved neural quantum states and shows simulation results on various Heisenberg models. Chapter 6 describes some computational software for implementing GCNNs as part of the software package NetKet. Chapter 7 is a bit of a thematic departure, and describes developing NQS methods to model quantum systems in the thermodynamic limit. Chapter 8 provides a summary and suggests avenues for future research.

description: We thoroughly investigate both transverse momentum and threshold resummation effects on scalar-pseudoscalar pair production via quark-antiquark annihilation at the $13~ \text{TeV}$ Large Hadron Collider at QCD NLO+NLL accuracy. A factorization method is introduced to properly supplement the soft-gluon (threshold) resummation contribution from parton distribution functions to the resummed results obtained by the Collins-Soper-Sterman resummation approach. We find that the impact of the threshold-resummation improved PDFs is comparable to the resummation effect of the partonic matrix element and can even predominate in high invariant mass regions. Moreover, the loop-induced gluon-gluon fusion channel in the type-I two-Higgs-doublet model is considered in our calculation. The numerical results show that the electroweak production via quark-antiquark annihilation dominates over the gluon-initiated QCD production by $1 \sim 2$ orders of magnitude.

description: In recent years, there has been a lot of interest in defining finite elements on nonstandard, polytopal elements, i.e., on polygons and polyhedra. Inspired by Arnold and Awanou's serendipity family of finite elements on cuboidal meshes, the dissertation generalizes the construction of direct serendipity and mixed finite elements to general planar, strictly convex polygons. This work also gives an explicit construction of direct serendipity finite elements on convex cuboidal hexahedra. Direct serendipity and mixed finite elements are H1 and H(div) conforming, respectively, and possess optimal order of accuracy for any order. They have a minimal number of degrees of freedom subject to conformity and accuracy constraints. The finite element shape functions are defined to be the full spaces of scalar or vector polynomials plus a space of supplemental functions, of which the choice is not unique. The direct serendipity elements are the precursors of the direct mixed elements in a de Rham complex. The convergence properties of these new families of finite elements are shown under the assumption of shape regularity, as well as some mild restrictions on the choice of supplemental functions. Numerical experiments on various meshes exhibit their performance, especially their potential value in applications where flexible polytopal meshes are advantageous.

description: Let G be a connected Lie group, LG its loop group, and PG->G the principal LG-bundle defined by quasi-periodic paths in G. This paper is devoted to differential geometry of the Atiyah algebroid A=T(PG)/LG of this bundle. Given a symmetric bilinear form on the Lie algebra g and the corresponding central extension of Lg, we consider the lifting problem for A, and show how the cohomology class of the Cartan 3-form on G arises as an obstruction. This involves the construction of a 2-form on PG with differential the pull-back of the Cartan form. In the second part of this paper we obtain similar LG-invariant primitives for the higher degree analogues of the Cartan form, and for their G-equivariant extensions.

description: In this paper we present an application of techniques from statistical signal processing to the problem of event detection in wireless sensor networks used for environmental monitoring. The proposed approach uses the well-established Principal Component Analysis (PCA) technique to build a compact model of the observed phenomena that is able to capture daily and seasonal trends in the collected measurements. We then use the divergence between actual measurements and model predictions to detect the existence of discrete events within the collected data streams. Our preliminary results show that this event detection mechanism is sensitive enough to detect the onset of rain events using the temperature modality of a wireless sensor network.
Universal Flow in the First fm/c at RHIC

Year: 2009
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: We will show how both elliptic and radial flow generated during the first fm/c at RHIC can be expressed in a form which is quasi-independent of the state of matter and depends only on the initial energy density profile. Descriptions based on partons or classical fields, thermalized or highly anisotropic, all lead to the same collective velocity given a few easily satisfied conditions. This significantly narrows the uncertainty for initializing hydrodynamic prescriptions.

description: Recent analysis on speech emotion recognition has made considerable advances with the use of MFCCs spectrogram features and the implementation of neural network approaches such as convolutional neural networks (CNNs). Capsule networks (CapsNet) have gained gratitude as alternatives to CNNs with their larger capacities for hierarchical representation. To address these issues, this research introduces a text-independent and speaker-independent SER novel architecture, where a dual-channel long short-term memory compressed-CapsNet (DC-LSTM COMP-CapsNet) algorithm is proposed based on the structural features of CapsNet. Our proposed novel classifier can ensure the energy efficiency of the model and adequate compression method in speech emotion recognition, which is not delivered through the original structure of a CapsNet. Moreover, the grid search approach is used to attain optimal solutions. Results witnessed an improved performance and reduction in the training and testing running time. The speech datasets used to evaluate our algorithm are: Arabic Emirati-accented corpus, English speech under simulated and actual stress corpus, English Ryerson audio-visual database of emotional speech and song corpus, and crowd-sourced emotional multimodal actors dataset. This work reveals that the optimum feature extraction method compared to other known methods is MFCCs delta-delta. Using the four datasets and the MFCCs delta-delta, DC-LSTM COMP-CapsNet surpasses all the state-of-the-art systems, classical classifiers, CNN, and the original CapsNet. Using the Arabic Emirati-accented corpus, our results demonstrate that the proposed work yields average emotion recognition accuracy of 89.3% compared to 84.7%, 82.2%, 69.8%, 69.2%, 53.8%, 42.6%, and 31.9% based on CapsNet, CNN, support vector machine, multi-layer perceptron, k-nearest neighbor, radial basis function, and naive Bayes, respectively.

Culture of peace vs. culture of legality (La cultura de la paz vs la cultura de la legalidad)
Creators: name: Leon-Ruiz, Daniel
Publisher: name: figshare
Year: 2024
Subjects: classificationCode: 480703
subject: Domestic human rights law

description: For many people, the word peace denotes primarily tranquility, while legality refers to everything established and governed by law. In this paper, the meaning of culture of peace and culture of legality is specifically analyzed, exploring their implications from an elementary perspective to human rights; on the other hand, the reader is invited to become involved in the study of these topics with the objective of forming a real and positive conscience from a universal and adaptive point of view to social development. Therefore, culture is examined as a driving force of values and how it adheres to peace and legality in society.

description: This dissertation studies four women artists working between Buenos Aires and Europe in the 1970s: Lea Lublin, Marie Orensanz, Mirtha Dermisache, and Margarita Paksa. During the military dictatorships of that decade, artists developed conceptual tactics – including performance-based works, coded uses of language and environmental installations – to critique the regimes in power. At the same time, the Centro de Arte y Comunicación, an interdisciplinary gallery established by Jorge Glusberg in Buenos Aires, championed conceptual art from Latin America, presenting the work of Lublin, Orensanz, Dermisache, and Paksa alongside North American and European practitioners. This dissertation compares some of the conceptual tactics developed by these artists during the Long Seventies in an effort to highlight their contributions to the convergent histories of feminism and conceptualism in Argentina. Connected by the ambitious international agenda of the Centro de Arte y Comunicación, and by personal friendships, Lublin, Orensanz, Dermisache, and Paksa each made work that responded to shared experiences of political and gendered domination while adapting nimbly to the specific cultural environments of Europe and the Americas. I therefore give careful attention to how their aesthetic strategies functioned across these varying environments. My analysis of these artists’ work, in its many forms, proposes a reading of conceptual art that hinges on the fundamentally reconfigured relations between artist and viewer taking place at the time. Focusing on “active spectatorship,” rather than on its dematerial or linguisitic qualities, this dissertation locates conceptual art’s criticality in its reliance on viewers that enter into it as embodied process. By opening not just the interpretation but also the creation of art to collaboration, I argue, these artists aimed their critique at the level of everyday life.

description: We present the first direct measurements of Casimir-Polder forces between solid surfaces and atomic gases in the transition regime between the electrostatic short-distance and the retarded long-distance limit. The experimental method is based on ultracold ground-state Rb atoms that are reflected from evanescent wave barriers at the surface of a dielectric glass prism. Our novel approach does not require assumptions about the potential shape. The experimental data confirm the theoretical prediction in the transition regime.

An Interdisciplinary Approach for the Automated Detection and Visualization of Media Bias in News Articles
Creators: name: Spinde, Timo
Publisher: name: arXiv
Year: 2021
Subjects: subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: Media coverage has a substantial effect on the public perception of events. Nevertheless, media outlets are often biased. One way to bias news articles is by altering the word choice. The automatic identification of bias by word choice is challenging, primarily due to the lack of gold-standard data sets and high context dependencies. In this research project, I aim to devise data sets and methods to identify media bias. To achieve this, I plan to research methods using natural language processing and deep learning while employing models and using analysis concepts from psychology and linguistics. The first results indicate the effectiveness of an interdisciplinary research approach. My vision is to devise a system that helps news readers become aware of media coverage differences caused by bias. So far, my best performing BERT-based model is pre-trained on a larger corpus consisting of distant labels, indicating that distant supervision has the potential to become a solution for the difficult task of bias detection.
