Overfitting in data science
WebFrom what I learned, having a training accuracy of 1.0 means that the model overfitting. However, seeing the validation accuracy (test accuracy), precision and mean cross-validation it suggest to me that the model is not overfitting and it will perform well on the unlabeled dataset. Am I wrong? Am I missing something? WebDec 7, 2024 · Overfitting is a term used in statistics that refers to a modeling error that occurs when a function corresponds too closely to a particular set of data. As a result, …
