Quantifying Aleatoric and Epistemic Uncertainty with Proper Scoring Rules

no code implementations18 Apr 2024 Paul Hofman, Yusuf Sale, Eyke Hüllermeier

Uncertainty representation and quantification are paramount in machine learning and constitute an important prerequisite for safety-critical applications.

Explaining Bayesian Optimization by Shapley Values Facilitates Human-AI Collaboration

no code implementations7 Mar 2024 Julian Rodemann, Federico Croppi, Philipp Arens, Yusuf Sale, Julia Herbinger, Bernd Bischl, Eyke Hüllermeier, Thomas Augustin, Conor J. Walsh, Giuseppe Casalicchio

We address this issue by proposing ShapleyBO, a framework for interpreting BO's proposals by game-theoretic Shapley values. They quantify each parameter's contribution to BO's acquisition function.

Second-Order Uncertainty Quantification: Variance-Based Measures

no code implementations30 Dec 2023 Yusuf Sale, Paul Hofman, Lisa Wimmer, Eyke Hüllermeier, Thomas Nagler

Uncertainty quantification is a critical aspect of machine learning models, providing important insights into the reliability of predictions and aiding the decision-making process in real-world applications.

Second-Order Uncertainty Quantification: A Distance-Based Approach

no code implementations2 Dec 2023 Yusuf Sale, Viktor Bengs, Michele Caprio, Eyke Hüllermeier

In the past couple of years, various approaches to representing and quantifying different types of predictive uncertainty in machine learning, notably in the setting of classification, have been proposed on the basis of second-order probability distributions, i. e., predictions in the form of distributions on probability distributions.

A Novel Bayes' Theorem for Upper Probabilities

no code implementations13 Jul 2023 Michele Caprio, Yusuf Sale, Eyke Hüllermeier, Insup Lee

In their seminal 1990 paper, Wasserman and Kadane establish an upper bound for the Bayes' posterior probability of a measurable set $A$, when the prior lies in a class of probability measures $\mathcal{P}$ and the likelihood is precise.

Is the Volume of a Credal Set a Good Measure for Epistemic Uncertainty?

no code implementations16 Jun 2023 Yusuf Sale, Michele Caprio, Eyke Hüllermeier

Adequate uncertainty representation and quantification have become imperative in various scientific disciplines, especially in machine learning and artificial intelligence.

Conformal Prediction with Partially Labeled Data

1 code implementation1 Jun 2023 Alireza Javanmardi, Yusuf Sale, Paul Hofman, Eyke Hüllermeier

While the predictions produced by conformal prediction are set-valued, the data used for training and calibration is supposed to be precise.

Quantifying Aleatoric and Epistemic Uncertainty in Machine Learning: Are Conditional Entropy and Mutual Information Appropriate Measures?

1 code implementation7 Sep 2022 Lisa Wimmer, Yusuf Sale, Paul Hofman, Bern Bischl, Eyke Hüllermeier

The quantification of aleatoric and epistemic uncertainty in terms of conditional entropy and mutual information, respectively, has recently become quite common in machine learning.
