Generalization of a model to new … WebMar 14, 2024 · What is Overfitting In Machine Learning? A statistical model is said to be overfitted when we feed it a lot more data than necessary. To make it relatable, imagine trying to fit into oversized apparel. When a model fits more data than it actually needs, it starts catching the noisy data and inaccurate values in the data.
WebJun 30, 2024 · Overfitting is not when loss on train is much lower than loss on test (that's normal!). It is when the loss on the test set is much worse than it "should be," eg worse than assuming the prior. I'm not certain that this will happen.
