👉 Robustness is a property of an object or system that allows it to resist changes in input and output without causing significant errors. It refers to how well an object or system can withstand variations in its inputs and outputs, and the degree to which it can adapt to these changes. In the context of machine learning models, robustness refers to the ability of a model to perform well on both training data (i.e., the input data) and unseen data. This is important because many machine learning
