Web28 de jan. de 2024 · The problem of Overfitting vs Underfitting finally appears when we talk about the polynomial degree. The degree represents how much flexibility is in the model, with a higher power allowing the model freedom to hit as many data points as possible. An underfit model will be less flexible and cannot account for the data. Web26 de ago. de 2024 · The k hyperparameter in k-nearest neighbors controls the bias-variance trade-off. Small values, such as k=1, result in a low bias and a high variance, whereas large k values, such as k=21, result in a high bias and a low variance.
