This approach is particularly useful when dealing with black box models, which are often difficult to interpret due to their complex structure. Post hoc explanations can take different forms, such as rule-based explanations or feature importance rankings. Rule-based explanations involve formulating a set of rules that explain the decision-making process of the model. Feature importance rankings, on the other hand, aim to identify the most influential features in the decision-making process. By employing post hoc explanations, researchers and practitioners can shed light on how machine learning models arrive at their predictions, allowing for better understanding and trust in AI systems.
Feature importance analysis
Feature importance analysis is a crucial aspect of machine learning models. It enables researchers and practitioners to understand the relevance and contribution of each feature in the model's decision-making process. By identifying and ranking the importance of features, practitioners can gain insights into the underlying patterns and relationships between variables. Various techniques, such as permutation feature importance, shapley value, or mutual information, can be employed to assess feature importance. These methods quantify the impact of individual features on the model's output and provide a measure of how much the performance of the model would deteriorate if a particular feature were excluded. Feature importance analysis not only assists in model interpretation, but it also aids in feature selection, where irrelevant or redundant features can be discarded, improving model efficiency and reducing overfitting. Overall, feature importance analysis is an essential tool in the arsenal of explainable AI, contributing to improved transparency and trustworthiness of machine learning models.
Local surrogate models
Local surrogate models are another approach to explainable AI. These models aim to provide interpretability for specific instances rather than the entire machine learning model as a whole. They help in understanding the workings of complex algorithms on an individual case basis.
