O sobreajuste
Example: O sobreajuste no modelo prejudicou a precisão das previsões.
Definition
"Overfitting" refers to a modeling error in data and AI where a model learns the training data too well, including its noise and outliers, resulting in poor performance on new, unseen data. It compromises the accuracy and generalization of predictions.
Etymology
The term "overfitting" originates from English, combining 'over-' meaning excessively, and 'fitting' from the verb 'fit', reflecting the concept of a model fitting the training data too closely. In Portuguese, 'sobreajuste' is a direct translation used in data science contexts.
