The foundations of cost-sensitive causal classification
[article]
2021
arXiv
pre-print
Preserved Fulltext
Other Versions
Cost-sensitive and causal classification methods have independently been proposed to improve the performance of classification models. ...
The framework encompasses a range of existing and novel performance measures for evaluating both causal and conventional classification models in a cost-sensitive as well as a cost-insensitive manner. ...
To this end, we formalize the foundations of cost-sensitive evaluation of conventional classification models by introducing the effect matrix as the difference between the confusion matrix of a classification ...

In this article, we therefore extend upon the expected value framework and formally introduce a cost-sensitive decision boundary for double binary causal classification, which is a linear function of the ...
The boundary allows causally classifying instances in the positive and negative treatment class to maximize the expected causal profit, which is introduced as the objective at hand in cost-sensitive causal ...
