Uncertainty quantification over graph with conformalized graph neural networks

K Huang, Y **, E Candes… - Advances in Neural …, 2024 - proceedings.neurips.cc
Abstract Graph Neural Networks (GNNs) are powerful machine learning prediction models
on graph-structured data. However, GNNs lack rigorous uncertainty estimates, limiting their …

Conformalized link prediction on graph neural networks

T Zhao, J Kang, L Cheng - Proceedings of the 30th ACM SIGKDD …, 2024 - dl.acm.org
Graph Neural Networks (GNNs) excel in diverse tasks, yet their applications in high-stakes
domains are often hampered by unreliable predictions. Although numerous uncertainty …

Optimal subsampling via predictive inference

X Wu, Y Huo, H Ren, C Zou - Journal of the American Statistical …, 2024 - Taylor & Francis
In the big data era, subsampling or sub-data selection techniques are often adopted to
extract a fraction of informative individuals from the massive data. Existing subsampling …

Selective conformal inference with false coverage-statement rate control

Y Bao, Y Huo, H Ren, C Zou - Biometrika, 2024 - academic.oup.com
Conformal inference is a popular tool for constructing prediction intervals. We consider here
the scenario of post-selection/selective conformal inference, that is, prediction intervals are …

Confidence on the focal: Conformal prediction with selection-conditional coverage

Y **, Z Ren - arxiv preprint arxiv:2403.03868, 2024 - arxiv.org
Conformal prediction builds marginally valid prediction intervals which cover the unknown
outcome of a randomly drawn new test point with a prescribed probability. In practice, a …

Model-free selective inference under covariate shift via weighted conformal p-values

Y **, EJ Candès - arxiv preprint arxiv:2307.09291, 2023 - arxiv.org
This paper introduces weighted conformal p-values for model-free selective inference.
Assume we observe units with covariates $ X $ and missing responses $ Y $, the goal is to …

Conformalizing machine translation evaluation

C Zerva, AFT Martins - Transactions of the Association for …, 2024 - direct.mit.edu
Several uncertainty estimation methods have been recently proposed for machine
translation evaluation. While these methods can provide a useful indication of when not to …

Conformal Alignment: Knowing When to Trust Foundation Models with Guarantees

Y Gui, Y **, Z Ren - arxiv preprint arxiv:2405.10301, 2024 - arxiv.org
Before deploying outputs from foundation models in high-stakes tasks, it is imperative to
ensure that they align with human values. For instance, in radiology report generation …

On the within-group fairness of screening classifiers

N Okati, S Tsirtsis… - … Conference on Machine …, 2023 - proceedings.mlr.press
Screening classifiers are increasingly used to identify qualified candidates in a variety of
selection processes. In this context, it has been recently shown that if a classifier is …

Conformal link prediction to control the error rate

A Marandon - arxiv preprint arxiv:2306.14693, 2023 - arxiv.org
Most link prediction methods return estimates of the connection probability of missing edges
in a graph. Such output can be used to rank the missing edges, from most to least likely to be …
