Why underfitting is called high bias and overfitting is called high

WebMar 20, 2024 · Ideally while model building you would want to choose a model which has low bias and low variance. A high bias model is a model that has underfit i.e - it has not understood your data correctly whereas a high variance model would mean a model which has overfit the training data and is not going to generalize the future predictions well. Web$\begingroup$ @Akhilesh Not really! Overfitting can also occur when training set is large. but there are more chances for underfitting than the chances of overfitting in general … WebHigher variance is an indication of overfitting in which the model loses the ability to generalize.
