This book was released on 2023-10-19 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Die Dissertation befasst sich mit der Anwendung von statistischem und maschinellem Lernen zur Modellierung der Verlustquote bei Ausfall (LGD). Im Forschungsgebiet der LGD-Modellierung gibt es eine Reihe von Fragen und Problemen, die bisher in der Literatur nicht berücksichtigt wurden. Erstens ist unklar, welche Merkmale einer LGD-Verteilung für die Prognosefähigkeit von Schätzmethoden entscheidend sind und welche Schätzmethode für die LGD-Modellierung am besten geeignet ist. Zweitens besteht ein Zielkonflikt zwischen der Transparenz und der Prognosegenauigkeit bei LGD-Schätzmethoden. Komplexe maschinelle Lernalgorithmen weisen eine bessere Vorhersageleistung auf, allerdings auf Kosten einer geringeren Erklärbarkeit. Umgekehrt bietet die lineare Regression eine hohe Interpretierbarkeit, scheint aber eine geringere Prognosegenauigkeit aufzuweisen. Um diesen Zielkonflikt zu lösen, besteht ein geeigneter Ansatz darin, die Vorhersagegenauigkeit der interpretierbaren linearen Regression durch maschinelles Lernen zu verbessern. Drittens stellt die Selektion optimaler Clustervariablen in der gruppierten Modellierung eine zu lösende Herausforderung dar. Die offenen Forschungsfragen werden in der Dissertation anhand von Kreditausfalldaten der Global Credit Data empirisch beantwortet.

Download or read book Artificial Intelligence and Credit Risk written by Rossella Locatelli and published by Springer Nature. This book was released on 2022-09-13 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the alternative techniques and data leveraged for credit risk, describing and analysing the array of methodological approaches for the usage of techniques and/or alternative data for regulatory and managerial rating models. During the last decade the increase in computational capacity, the consolidation of new methodologies to elaborate data and the availability of new information related to individuals and organizations, aided by the widespread usage of internet, set the stage for the development and application of artificial intelligence techniques in enterprises in general and financial institutions in particular. In the banking world, its application is even more relevant, thanks to the use of larger and larger data sets for credit risk modelling. The evaluation of credit risk has largely been based on client data modelling; such techniques (linear regression, logistic regression, decision trees, etc.) and data sets (financial, behavioural, sociologic, geographic, sectoral, etc.) are referred to as “traditional” and have been the de facto standards in the banking industry. The incoming challenge for credit risk managers is now to find ways to leverage the new AI toolbox on new (unconventional) data to enhance the models’ predictive power, without neglecting problems due to results’ interpretability while recognizing ethical dilemmas. Contributors are university researchers, risk managers operating in banks and other financial intermediaries and consultants. The topic is a major one for the financial industry, and this is one of the first works offering relevant case studies alongside practical problems and solutions.

Download or read book Credit Risk Modeling written by David Lando and published by Princeton University Press. This book was released on 2009-12-13 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Credit risk is today one of the most intensely studied topics in quantitative finance. This book provides an introduction and overview for readers who seek an up-to-date reference to the central problems of the field and to the tools currently used to analyze them. The book is aimed at researchers and students in finance, at quantitative analysts in banks and other financial institutions, and at regulators interested in the modeling aspects of credit risk. David Lando considers the two broad approaches to credit risk analysis: that based on classical option pricing models on the one hand, and on a direct modeling of the default probability of issuers on the other. He offers insights that can be drawn from each approach and demonstrates that the distinction between the two approaches is not at all clear-cut. The book strikes a fruitful balance between quickly presenting the basic ideas of the models and offering enough detail so readers can derive and implement the models themselves. The discussion of the models and their limitations and five technical appendixes help readers expand and generalize the models themselves or to understand existing generalizations. The book emphasizes models for pricing as well as statistical techniques for estimating their parameters. Applications include rating-based modeling, modeling of dependent defaults, swap- and corporate-yield curve dynamics, credit default swaps, and collateralized debt obligations.

Download or read book Recent Methods from Statistics and Machine Learning for Credit Scoring written by Anne Kraus and published by Cuvillier Verlag. This book was released on 2014-07-08 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Credit scoring models are the basis for financial institutions like retail and consumer credit banks. The purpose of the models is to evaluate the likelihood of credit applicants defaulting in order to decide whether to grant them credit. The area under the receiver operating characteristic (ROC) curve (AUC) is one of the most commonly used measures to evaluate predictive performance in credit scoring. The aim of this thesis is to benchmark different methods for building scoring models in order to maximize the AUC. While this measure is used to evaluate the predictive accuracy of the presented algorithms, the AUC is especially introduced as direct optimization criterion.
