Book Synopsis Comparaison de méthodes d'imputation de données manquantes dans un contexte de modèles d'apprentissage statistique by : Simon Bouchard
Download or read book Comparaison de méthodes d'imputation de données manquantes dans un contexte de modèles d'apprentissage statistique written by Simon Bouchard and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le sujet de ce mémoire concerne l'utilisation de données incomplètes qui sont utilisées à des fins d'apprentissage statistique, dans un contexte où une méthode de traitement des données manquantes a été appliquée aux données. La problématique motivant ce travail est la prédiction de l'abandon scolaire chez les étudiants collégiaux. La caractéristique principale de la non-réponse au sein de ces données est que les étudiants ayant le statut d'immigrant ont une non-réponse quasi complète pour certaines variables. À partir d'une étude de simulation répliquant le comportement des données collégiales, différentes méthodes d'imputation sont utilisées sur des jeux de données ayant différentes configurations de non-réponse. Ces données imputées sont ensuite utilisées pour entraîner des modèles d'apprentissage statistique afin d'en évaluer les performances. À partir des résultats de cette étude de simulation, les combinaisons de méthodes d'imputation et de modèles d'apprentissage statistique ayant le mieux performé au niveau des prédictions sont appliquées aux données collégiales afin de déterminer quelles méthodes d'imputation permettent d'obtenir les meilleures performances prédictives.

Book Synopsis FinTech in Financial Inclusion: Machine Learning Applications in Assessing Credit Risk by : Majid Bazarbash
Download or read book FinTech in Financial Inclusion: Machine Learning Applications in Assessing Credit Risk written by Majid Bazarbash and published by International Monetary Fund. This book was released on 2019-05-17 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in digital technology and big data have allowed FinTech (financial technology) lending to emerge as a potentially promising solution to reduce the cost of credit and increase financial inclusion. However, machine learning (ML) methods that lie at the heart of FinTech credit have remained largely a black box for the nontechnical audience. This paper contributes to the literature by discussing potential strengths and weaknesses of ML-based credit assessment through (1) presenting core ideas and the most common techniques in ML for the nontechnical audience; and (2) discussing the fundamental challenges in credit risk analysis. FinTech credit has the potential to enhance financial inclusion and outperform traditional credit scoring by (1) leveraging nontraditional data sources to improve the assessment of the borrower’s track record; (2) appraising collateral value; (3) forecasting income prospects; and (4) predicting changes in general conditions. However, because of the central role of data in ML-based analysis, data relevance should be ensured, especially in situations when a deep structural change occurs, when borrowers could counterfeit certain indicators, and when agency problems arising from information asymmetry could not be resolved. To avoid digital financial exclusion and redlining, variables that trigger discrimination should not be used to assess credit rating.

Book Synopsis Semiparametric Theory and Missing Data by : Anastasios Tsiatis
Download or read book Semiparametric Theory and Missing Data written by Anastasios Tsiatis and published by Springer Science & Business Media. This book was released on 2007-01-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes current knowledge regarding the theory of estimation for semiparametric models with missing data, in an organized and comprehensive manner. It starts with the study of semiparametric methods when there are no missing data. The description of the theory of estimation for semiparametric models is both rigorous and intuitive, relying on geometric ideas to reinforce the intuition and understanding of the theory. These methods are then applied to problems with missing, censored, and coarsened data with the goal of deriving estimators that are as robust and efficient as possible.

Book Synopsis World Development Report 2016 by : World Bank Group
Download or read book World Development Report 2016 written by World Bank Group and published by World Bank Publications. This book was released on 2016-01-14 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital technologies are spreading rapidly, but digital dividends--the broader benefits of faster growth, more jobs, and better services--are not. If more than 40 percent of adults in East Africa pay their utility bills using a mobile phone, why can’t others around the world do the same? If 8 million entrepreneurs in China--one third of them women--can use an e-commerce platform to export goods to 120 countries, why can’t entrepreneurs elsewhere achieve the same global reach? And if India can provide unique digital identification to 1 billion people in five years, and thereby reduce corruption by billions of dollars, why can’t other countries replicate its success? Indeed, what’s holding back countries from realizing the profound and transformational effects that digital technologies are supposed to deliver? Two main reasons. First, nearly 60 percent of the world’s population are still offline and can’t participate in the digital economy in any meaningful way. Second, and more important, the benefits of digital technologies can be offset by growing risks. Startups can disrupt incumbents, but not when vested interests and regulatory uncertainty obstruct competition and the entry of new firms. Employment opportunities may be greater, but not when the labor market is polarized. The internet can be a platform for universal empowerment, but not when it becomes a tool for state control and elite capture. The World Development Report 2016 shows that while the digital revolution has forged ahead, its 'analog complements'--the regulations that promote entry and competition, the skills that enable workers to access and then leverage the new economy, and the institutions that are accountable to citizens--have not kept pace. And when these analog complements to digital investments are absent, the development impact can be disappointing. What, then, should countries do? They should formulate digital development strategies that are much broader than current information and communication technology (ICT) strategies. They should create a policy and institutional environment for technology that fosters the greatest benefits. In short, they need to build a strong analog foundation to deliver digital dividends to everyone, everywhere.
Book Synopsis Defining and Selecting Key Competencies by : Dominique Simone Rychen
Download or read book Defining and Selecting Key Competencies written by Dominique Simone Rychen and published by Seattle ; Toronto : Hogrefe & Huber. This book was released on 2001 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: What skills and competencies are needed for individuals to lead a successful and responsible life, both in the workplace and in other social environments, and for society to face the challenges of the present and future? What are the foundations (normative, theoretical, and conceptual) for defining and selecting a limited set of key competencies? These are among the important questions, of considerable relevance for fields such as education and training, employment, social affairs and welfare, health, and justice, that provided the starting point for an international and interdisciplinary endeavor carried out by the Swiss Federal Statistical Office and the National Center for Education Statistics, US Department of Education under the auspices of the Organization for Economic Co-operation and Development (OECD). The current volume, which has resulted from this work, compiles essays from renowned scholars who explore these questions from multiple perspectives (anthropology, economics, history, philosophy, psychology, and sociology), along with commentaries from leading representatives of policy and practice who provide an important complement to the reflection on key competencies. This volume thus presents a multifaceted sketch of issues related to defining and selecting key competencies in an open, still ongoing debate at national and international levels.
