While we have managed to improve the base model, there are still many ways to tune the model including polynomial feature generation, sklearn feature selection, and tuning of more hyperparameters for grid search. These will be the focus of Part 2! In the meantime, thanks for reading and the code can be found here. WebOct 26, 2024 · The class weighing can be defined multiple ways; for example: Domain expertise, determined by talking to subject matter experts.; Tuning, determined by a hyperparameter search such as a grid search.; Heuristic, specified using a general best practice.; A best practice for using the class weighting is to use the inverse of the class …
