Rethinking Missing Data: Aleatoric Uncertainty-Aware Recommendation

open access: yesIEEE Transactions on Big Data, 2023
Historical interactions are the default choice for recommender model training, which typically exhibit high sparsity, i.e., most user-item pairs are unobserved missing data. A standard choice is treating the missing data as negative training samples and estimating interaction likelihood between user-item pairs along with the observed interactions.

Fairness through Aleatoric Uncertainty

open access: yesProceedings of the 32nd ACM International Conference on Information and Knowledge Management, 2023
We propose a simple yet effective solution to tackle the often-competing goals of fairness and utility in classification tasks. While fairness ensures that the model's predictions are unbiased and do not discriminate against any particular group or individual, utility focuses on maximizing the model's predictive performance.

Intrinsic randomness in epidemic modelling beyond statistical uncertainty

open access: yesCommunications Physics, 2023
Uncertainty can be classified as either aleatoric (intrinsic randomness) or epistemic (imperfect knowledge of parameters). The majority of frameworks assessing infectious disease risk consider only epistemic uncertainty.

Quantifying uncertainty of machine learning methods for loss given default

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Machine learning has increasingly found its way into the credit risk literature. When applied to forecasting credit risk parameters, the approaches have been found to outperform standard statistical models. The quantification of prediction uncertainty is
