My Model Was Cheating on Its Own Test
Data scientists often strive for model accuracy, but what happens when a model gains an unfair advantage? In a recent *Towards Data Science* post, an author discovered their car price prediction model was "cheating" – a preprocessing pipeline inadvertently allowed it to glimpse the test set. This resulted in a deceptively high R-squared score. The experience highlights a critical pitfall in machine learning workflows and the importance of rigorous validation.
