Lazy Classication with Interval Pattern Structures: Application to Credit Scoring
P. 43-54.
Pattern structures allow one to approach the knowledge extraction problem in case of arbitrary object descriptions. They provide the way to apply Formal Concept Analysis (FCA) techniques to non-binary contexts. However, in order to produce classification rules a concept lattice should be built. For non-binary contexts this procedure may take much time and resources. In order to tackle this problem, we introduce a modication of the lazy associative classification algorithm and apply it to credit scoring. The resulting quality of classification is compared to existing methods adopted in bank systems.

Credit risk is the most significant risk by impact for any bank and financial institution.
Accurate credit risk assessment affects an organisation’s balance sheet and income
statement, since credit risk strategy determines pricing, and might even influence
seemingly unrelated domains, e.g. marketing, and decision-making. This article aims at
providing a systemic review of the most recent (2016–2021) articles, identifying ...

The paper briefly introduces multiple classifier systems and describes a new algorithm, which improves classification accuracy by means of recommendation of a proper algorithm to an object classification. This recommendation is done assuming that a classifier is likely to predict the label of the object correctly if it has correctly classified its neighbors. The process ...

In many practical tasks it is needed to estimate an effect of treatment on individual level. For example, in medicine it is essential to determine the patients that would benefit from a certain medicament. In marketing, knowing the persons that are likely to buy a new product would reduce the amount of spam. In this ...
