Interpretable Machine Learning Techniques for Enhancing Weather and Climate Prediction Accuracy and Transparency

Core Concepts

Interpretable machine learning techniques are crucial for enhancing the credibility, utility, and scientific insights of weather and climate prediction models by providing transparency into their decision-making processes.

Abstract

This comprehensive survey examines the current advancements in applying explainability techniques to various weather and climate prediction models. It categorizes the explainability methods into two main paradigms:

Post-hoc interpretability techniques that explain pre-trained models, such as perturbation-based, game theory-based, and gradient-based attribution methods. These methods can uncover the key meteorological factors and relationships driving the model's predictions.

Designing inherently interpretable models from scratch using architectures like tree ensembles and explainable neural networks. These self-explainable models aim to provide transparency into their decision-making logic.

The survey summarizes how each explainability technique offers insights into the predictions, revealing novel meteorological discoveries captured by machine learning. It also discusses research challenges around achieving deeper mechanistic interpretations aligned with physical principles, developing standardized evaluation benchmarks, integrating interpretability into iterative model development workflows, and providing explainability for large foundation models in meteorology.

How can the integration of interpretable machine learning techniques with physical-based numerical models lead to more accurate and reliable weather and climate predictions

The integration of interpretable machine learning techniques with physical-based numerical models can significantly enhance the accuracy and reliability of weather and climate predictions. By combining the strengths of both approaches, we can overcome the limitations of each method individually.
Interpretable machine learning techniques, such as post-hoc explanation methods like SHAP and LIME, can provide insights into the inner workings of complex machine learning models. These methods can help identify the key features and relationships that drive predictions, making the decision-making process more transparent and understandable.

Furthermore, interpretable machine learning techniques can help identify potential biases or errors in the predictions made by numerical models. By comparing the outputs of both types of models and analyzing the discrepancies, we can improve the overall accuracy and reliability of the predictions. This integration can also help in refining the physical parameterizations used in numerical models by providing insights into the relationships captured by machine learning models.
Overall, the integration of interpretable machine learning techniques with physical-based numerical models can lead to more robust and trustworthy weather and climate predictions by leveraging the strengths of both approaches and addressing their respective limitations.

What are the potential limitations and drawbacks of the current explainability methods in capturing the complex, nonlinear relationships in meteorological systems

While explainability methods like SHAP, LIME, and Grad-CAM offer valuable insights into the inner workings of machine learning models, they also have potential limitations in capturing the complex, nonlinear relationships in meteorological systems. Some of the drawbacks of current explainability methods include:

Sensitivity to Feature Interactions: Many explainability methods focus on individual feature importance and may not capture the interactions between features accurately. In meteorological systems, the relationships between different variables can be highly nonlinear and interconnected, making it challenging to attribute predictions solely to individual features.

Limited Scope of Interpretation: Current explainability methods may provide insights at a local level for specific predictions but may not offer a comprehensive understanding of the overall model behavior. Understanding the holistic behavior of machine learning models in meteorology requires capturing the complex interactions and dynamics across multiple variables and spatial-temporal scales.

Computational Complexity: Some explainability methods, especially those based on gradient calculations, can be computationally intensive, particularly for deep neural networks and large datasets. This complexity can limit the scalability and practicality of these methods for real-time applications in meteorology.

Assumption of Linearity: Certain explainability methods assume linearity in the relationships between input features and predictions, which may not hold true in meteorological systems characterized by nonlinear and chaotic dynamics. This can lead to oversimplified interpretations that do not fully capture the complexity of atmospheric processes.

Addressing these limitations will be crucial for developing more robust and comprehensive explainability methods that can effectively capture the intricate relationships and dynamics in meteorological systems.
