Monotonicity constraints are used in machine learning and statistical models to ensure that the relationship between features and the target variable is either entirely non-decreasing or non-increasing. This constraint is particularly useful in scenarios where domain knowledge dictates that an increase or decrease in a feature should consistently lead to an increase or decrease in the prediction, improving model interpretability and trustworthiness.
A 'black box' is a system or device whose internal workings are not visible or understood, but whose input and output are known. It is often used in contexts like artificial intelligence or engineering to describe systems where the focus is on input-output behavior rather than the internal processes.
Counterfactual explanation is a method used in machine learning and artificial intelligence to provide insights into model predictions by describing how a different outcome could be achieved. It focuses on altering input features to change the prediction, thus offering transparency and interpretability in complex models.
