Carefully choose the baseline: Lessons learned from applying XAI attribution methods for regression tasks in geoscience

no code implementations19 Aug 2022 Antonios Mamalakis, Elizabeth A. Barnes, Imme Ebert-Uphoff

We highlight that different baselines can lead to different insights for different science questions and, thus, should be chosen accordingly.

Attribute Decision Making +3

Investigating the fidelity of explainable artificial intelligence methods for applications of convolutional neural networks in geoscience

1 code implementation7 Feb 2022 Antonios Mamalakis, Elizabeth A. Barnes, Imme Ebert-Uphoff

Convolutional neural networks (CNNs) have recently attracted great attention in geoscience due to their ability to capture non-linear system behavior and extract predictive spatiotemporal patterns.

Controlled abstention neural networks for identifying skillful predictions for regression problems

1 code implementation16 Apr 2021 Elizabeth A. Barnes, Randal J. Barnes

We introduce a novel loss function, termed "abstention loss", that allows neural networks to identify forecasts of opportunity for regression problems.

Controlled abstention neural networks for identifying skillful predictions for classification problems

1 code implementation16 Apr 2021 Elizabeth A. Barnes, Randal J. Barnes

The NotWrong loss introduces an abstention class that allows the network to identify the more confident samples and abstain (say "I don't know") on the less confident samples.

Neural Network Attribution Methods for Problems in Geoscience: A Novel Synthetic Benchmark Dataset

1 code implementation18 Mar 2021 Antonios Mamalakis, Imme Ebert-Uphoff, Elizabeth A. Barnes

Here, we provide a framework, based on the use of additively separable functions, to generate attribution benchmark datasets for regression problems for which the ground truth of the attribution is known a priori.

Will Artificial Intelligence supersede Earth System and Climate Models?

no code implementations22 Jan 2021 Christopher Irrgang, Niklas Boers, Maike Sonnewald, Elizabeth A. Barnes, Christopher Kadow, Joanna Staneva, Jan Saynisch-Wagner

We outline a perspective of an entirely new research branch in Earth and climate sciences, where deep neural networks and Earth system models are dismantled as individual methodological approaches and reassembled as learning, self-validating, and interpretable Earth system model-network hybrids.

Identifying Opportunities for Skillful Weather Prediction with Interpretable Neural Networks

no code implementations14 Dec 2020 Elizabeth A. Barnes, Kirsten Mayer, Benjamin Toms, Zane Martin, Emily Gordon

For Earth scientists, these relevant regions for the neural network's prediction are by far the most important product of our study: they provide scientific insight into the physical mechanisms that lead to enhanced weather predictability.

Physically Interpretable Neural Networks for the Geosciences: Applications to Earth System Variability

no code implementations4 Dec 2019 Benjamin A. Toms, Elizabeth A. Barnes, Imme Ebert-Uphoff

As such, neural networks have often been used within the geosciences to most accurately identify a desired output given a set of inputs, with the interpretation of what the network learns used as a secondary metric to ensure the network is making the right decision for the right reason.
