Striking the Right Balance: Understanding Underfitting and Overfitting …
The bias–variance decomposition forms the conceptual basis for regression regularization methods such as Lasso and ridge regression. Regularization methods introduce bias into the regression solution that can reduce variance considerably relative to the ordinary least squares (OLS) solution. Although the OLS solution provides non-biased regression estimates, the lower variance solutions produced by regularization techniques provide superior MSE performance. WebThe Bias-Variance Tradeoff is an imperative concept in machine learning that states that expanding the complexity of a model can lead to lower bias but higher variance, and vice versa. It is important to adjust the complexity of a model with the exactness that's carved in order to realize optimal results.
