| | |
| A hyperparameter is a machine learning parameter whose value is chosen before a learning algorithm is trained.
| |
| | |
| Hyperparameters should not be confused with parameters . In machine learning, the label parameter is used to identify variables whose values are learned during training. The prefix hyper is used to identify higher-level parameters that control the learning process.
| |
| | |
| Every variable that an AI engineer or ML engineer chooses before model training begins can be referred to as a hyperparameter -- as long as the value of the variable remains the same when training ends.
| |
| | |
| It’s important to choose the right hyperparameters before training begins because this type of variable has a direct impact on the performance of the resulting machine learning model. Examples of hyperparameters in machine learning include:
| |
| | |
| Model architectureLearning rateNumber of epochsNumber of branches in a decision treeNumber of clusters in a clustering algorithm
| |
| | |
| Hyperparameters may also be referred to as meta parameters.
| |
| | |
| The process of choosing which hyperparameters to use is called hyperparameter tuning. The process of tuning may also be referred to as hyperparameter optimization (HPO).
