Model interpretability

Definition

Model interpretability refers to the ability to understand and explain how machine learning models make decisions based on the input data. In combustion research, where complex systems are often modeled, interpretability is crucial for validating predictions, ensuring safety, and improving model transparency. This concept helps researchers connect model outputs with real-world phenomena, making it easier to trust and utilize AI-driven insights effectively.
