WebSep 19, 2024 · To solve this problem first let’s use the parameter max_depth. From a difference of 25%, we have achieved a difference of 20% by just tuning the value o one hyperparameter. Similarly, let’s use the n_estimators. Again by pruning another hyperparameter, we are able to solve the problem of overfitting even more. WebJan 16, 2024 · So I wouldn't use the iris dataset to showcase overfitting. Choose a larger, messier dataset, and then you can start working towards reducing the bias and variance of the model (the "causes" of overfitting). Then you can start exploring tell-tale signs of whether it's a bias problem or a variance problem. See here:

5 Machine Learning Techniques to Solve Overfitting

WebAbove is the representation of best fit line and overfitting line, we can observe that in the case of best fit line, the errors between the data points are somewhat identical, however, … WebIncreasing the model complexity. Your model may be underfitting simply because it is not complex enough to capture patterns in the data. Using a more complex model, for instance by switching from a linear to a non-linear model or by adding hidden layers to your neural network, will very often help solve underfitting.
