Overfitting bias variance tradeoff

WebApr 11, 2024 · The goal is to find a model that balances bias and variance, which is known as the bias-variance tradeoff. Key points to remember: The bias of the model represents how well it fits the training set. The variance of the model represents how well it fits unseen cases in the validation set. Underfitting is characterized by a high bias and a low ... WebFeb 28, 2024 · Therefore, the model is said to have high variance. N00b just got a taste of Bias-Variance Tradeoff. To keep the bias low, he needs a complex model (e.g. a higher degree polynomial), but a complex model has a tendency to overfit and increase the variance.
