Linear regression tuning
Nettet31. okt. 2024 · If you are interested in the performance of a linear model you could just try linear or ridge regression, but don't bother with it during your XGBoost parameter tuning. Drop the dimension base_score from your hyperparameter search space. This should not have much of an effect with sufficiently many boosting iterations (see XGB parameter … Nettet20. des. 2024 · In general, you can use SVR to solve the same problems you would use linear regression for. Unlike linear regression, though, SVR also allows you to model non-linear relationships between variables and provides the flexibility to adjust the model's robustness by tuning hyperparameters. An intuitive explanation of Support Vector …

What is a Hyperparameter in a Machine Learning Model? A model hyperparameter is a configuration that is external to the model and whose value cannot be estimated from data. They are often used in processes to help estimate model parameters. They are often specified by the practitioner.
