WebMar 24, 2024 · Image Source: Author. Based on the Bias and Variance relationship a Machine Learning model can have 4 possible scenarios: High Bias and High Variance (The Worst-Case Scenario); Low Bias and Low Variance (The Best-Case Scenario); Low Bias and High Variance (Overfitting); High Bias and Low Variance (Underfitting); Complex … WebRegularization, in the context of machine learning, refers to the process of modifying a learning algorithm so as to prevent overfitting. This generally involves imposing some sort of smoothness constraint on the learned model. This smoothness may be enforced explicitly, by fixing the number of parameters in the model, or by augmenting the cost function as in …
