Tools for Extracting Spatio-Temporal Patterns in Meteorological Image Sequences: From Feature Engineering to Attention-Based Neural Networks

no code implementations22 Oct 2022 Akansha Singh Bansal, Yoonjin Lee, Kyle Hilburn, Imme Ebert-Uphoff

Then we provide an overview of many different concepts and techniques that are helpful for the interpretation of meteorological image sequences, such as (1) feature engineering methods to strengthen the desired signal in the input, using meteorological knowledge, classic image processing, harmonic analysis and topological data analysis (2) explain how different convolution filters (2D/3D/LSTM-convolution) can be utilized strategically in convolutional neural network architectures to find patterns in both space and time (3) discuss the powerful new concept of 'attention' in neural networks and the powerful abilities it brings to the interpretation of image sequences (4) briefly survey strategies from unsupervised, self-supervised and transfer learning to reduce the need for large labeled datasets.

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.

A Primer on Topological Data Analysis to Support Image Analysis Tasks in Environmental Science

1 code implementation21 Jul 2022 Lander Ver Hoef, Henry Adams, Emily J. King, Imme Ebert-Uphoff

One of the core strengths of persistent homology is how interpretable it can be, so throughout this paper we discuss not just the patterns we find, but why those results are to be expected given what we know about the theory of persistent homology.

The Need for Ethical, Responsible, and Trustworthy Artificial Intelligence for Environmental Sciences

no code implementations15 Dec 2021 Amy McGovern, Imme Ebert-Uphoff, David John Gagne II, Ann Bostrom

In fact, much can be learned from other domains where AI was introduced, often with the best of intentions, yet often led to unintended societal consequences, such as hard coding racial bias in the criminal justice system or increasing economic inequality through the financial system.

CIRA Guide to Custom Loss Functions for Neural Networks in Environmental Sciences -- Version 1

no code implementations17 Jun 2021 Imme Ebert-Uphoff, Ryan Lagerquist, Kyle Hilburn, Yoonjin Lee, Katherine Haynes, Jason Stock, Christina Kumler, Jebb Q. Stewart

Standard loss functions do not cover all the needs of the environmental sciences, which makes it important for scientists to be able to develop their own custom loss functions so that they can implement many of the classic performance measures already developed in environmental science, including measures developed for spatial model verification.

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.

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.
