Uncertainty Quantification in Pairwise Difference Learning for Classification

Read the original on arXiv AI →

The paper introduces a pairwise difference learning (PDL) approach for classification, where a model predicts the outcome difference between two instances and uses these predictions to classify a query instance by averaging over training examples. It presents a meta‑learning technique tailored to this setting and tackles uncertainty quantification by decomposing total uncertainty into aleatoric and epistemic components, extending these measures to PDL. Extensive empirical studies evaluate both predictive accuracy and the model’s awareness of uncertainty.

Pairwise Difference Learning for Classification

The paper introduces Pairwise Difference Learning (PDL) for classification, extending a meta‑learning technique originally designed for regression. PDL learns a function that predicts the difference between outcomes of two instances; predictions for a new instance are obtained by averaging differences with all training examples. Experiments show that the resulting PDL classifier surpasses state‑of‑the‑art methods, and the authors release a user‑friendly Python implementation.

An Axiomatic Assessment of Entropy- and Variance-based Uncertainty Quantification in Regression

arXiv:2504. 18433v3 Announce Type: replace Abstract: Uncertainty quantification is crucial in machine learning, yet most (axiomatic) studies of uncertainty measures focus on classification, leaving a gap in regression settings with limited formal justification and evaluations.

Uncertainty-Aware Learning from Multi-Expert Interval Targets

The paper introduces a method for learning from multiple experts who provide interval labels, addressing both within‑label imprecision and between‑expert variation. It harmonizes diverse label vocabularies into a shared probabilistic space, retains individual intervals using a mixture of Beta distributions, and decomposes predictive uncertainty into components that are matched to their corresponding sources of label uncertainty. On sea‑ice concentration data, the approach achieves a 31% reduction in mean absolute error compared to hard‑label baselines and outperforms several aggregation and interval‑regression methods.
