Developing a Novel Fair-Loan Classifier through a Multi-Sensitive Debiasing Pipeline: DualFair
نویسندگان
چکیده
Machine learning (ML) models are increasingly being used for high-stake applications that can greatly impact people’s lives. Sometimes, these be biased toward certain social groups on the basis of race, gender, or ethnicity. Many prior works have attempted to mitigate this “model discrimination” by updating training data (pre-processing), altering model process (in-processing), manipulating output (post-processing). However, more work done in extending situation intersectional fairness, where we consider multiple sensitive parameters (e.g., race) and options black white), thus allowing greater real-world usability. Prior fairness has also suffered from an accuracy–fairness trade-off prevents both accuracy high. Moreover, previous literature not clearly presented holistic metrics with fairness. In paper, address all three problems (a) creating a bias mitigation technique called DualFair (b) developing new metric (i.e., AWI, measure algorithm based upon inconsistent counterfactual predictions) handle Lastly, test our novel method using comprehensive U.S. mortgage lending dataset show classifier, fair loan predictor, obtains relatively high metrics.

متن کاملA novel multi-alignment pipeline for high-throughput sequencing data
Mapping reads to a reference sequence is a common step when analyzing allele effects in high-throughput sequencing data. The choice of reference is critical because its effect on quantitative sequence analysis is non-negligible. Recent studies suggest aligning to a single standard reference sequence, as is common practice, can lead to an underlying bias depending on the genetic distances of the...
متن کاملA Novel Multi-stage Classifier for Face Recognition
A novel face recognition scheme based on multi-stages classifier, which includes methods of support vector machine (SVM), Eigenface, and random sample consensus (RANSAC), is proposed in this paper. The whole decision process is conducted cascade coarse-to-fine stages. The first stage adopts one-against-one-SVM (OAO-SVM) method to choose two possible classes best similar to the testing image. In...
