How to choose hyperparameters
Web21 feb. 2024 · Landing on the best possible combinations of hyperparameters is one of the most important, as well as confusing, choices we could be faced with when developing a machine learning model. Even the most seasoned experts would agree that the algorithms and processes involved in choosing the best hyperparameters are highly complex. Web11 apr. 2024 · Ideally, you’d like a very steep curve initially (where a “small number” of categories cover the “majority” of the data) and then a long, shallow tail approaching 100% that corresponds to the data to be binned in “other” or dropped. There aren’t hard and fast rules on making these decisions. I decided to use 80% as my threshold.
