Low-Default Portfolio/One-Class Classification: A Literature Review

Consider a bank which wishes to decide whether a credit applicant will obtain credit or not. The bank has to assess if the applicant will be able to redeem the credit. This is done by estimating the probability that the applicant will default prior to the maturity of the credit. To estimate this probability of default it is first necessary to identify criteria which separate the good from the bad creditors, such as loan amount and age or factors concerning the income of the applicant. The question then arises of how a bank identifies a sufficient number of selective criteria that possess the necessary discriminatory power. As a solution, many traditional binary classification methods have been proposed with varying degrees of success. However, a particular problem with credit scoring is that defaults are only observed for a small subsample of applicants. An imbalance exists between the ratio of non-defaulters to defaulters. This has an adverse effect on the aforementioned binary classification method. Recently one-class classification approaches have been proposed to address the imbalance problem. The purpose of this literature review is three fold: (I) present the reader with an overview of credit scoring; (ii) review existing binary classification approaches; and (iii) introduce and examine one-class classification approaches

The Epigenetic Research Program (EPR): a transdisciplinary approach for the dynamics of knowledge, society - and beyond

'Mit dem 'epigenetischen Zugang' wurde ein einheitliches Forschungsprogramm aufgebaut, das zur Analyse von 'wissensbasierten Prozessen' in einer Unzahl von Bereichen dient. Konkret wurde mit dem epigenetischen Programm bislang auf der einen Seite ein anspruchsvolles 'transdisziplinäres Forschungsprogramm' konstruiert und auf der anderen Seite eine Reihe von Anwendungen im Bereich von Organisationsanalysen oder auch 'Nationalen Innovationssystemen' durchgeführt. Darüberhinaus erlaubt das epigenetische Programm, sich jenseits der gegenwärtig diskutierten Merkmale von 'Wissensgesellschaften' wie der Diffusion von Informations- und Kommunikationstechnologien oder der Ausweitung in den traditionellen Stätten der Wissensproduktion - Universitäten und Forschungsinstitute - zu bewegen. Zu guter Letzt sei der Hinweis angebracht, daß gerade die neue Architektur von Wissens- und Informationsgesellschaften innovative Schlaglichter auf Fragen der gesellschaftlichen Ungleichheit wirft und gegenwärtige Problemfelder in diesem Bereich scharf zu akzentuieren vermag.' (Autorenreferat)'With the 'epigenetic approach', an entire research program has been set up which is devoted to the study of 'knowledge-based processes' in human societies - and beyond. More concretely, an epigenetic approach has been built up in which two different areas are addressed and dealt with simultaneously, namely theoretical foundations for the analysis of 'knowledge based processes' and a comparatively large number of empirical applications, ranging from the study of organizations to the level of 'National Innovation Systems'. Moreover, the emphasis on 'knowledge and information societies' is not motivated by current reconfigurations via communication and information technologies or the expansion of 'knowledge generating capacities' beyond the confines of traditional universities or research institutes. Likewise, 'knowledge and information societies' are not conceptualized as a stage beyond socio-economic inequality, contrasting it, for example, to traditional 'class societies', but, once again, as a theoretical approach which offers new insights into the basic structure of current societal disparities.'

Protein Structure

Since the dawn of recorded history, and probably even before, men and women have been grasping at the mechanisms by which they themselves exist. Only relatively recently, did this grasp yield anything of substance, and only within the last several decades did the proteins play a pivotal role in this existence. In this expose on the topic of protein structure some of the current issues in this scientific field are discussed. The aim is that a non-expert can gain some appreciation for the intricacies involved, and in the current state of affairs. The expert meanwhile, we hope, can gain a deeper understanding of the topic
