It means you have a set of models (which differ from each other in their parameter values, which lie on a grid). What you do is you then train each of the models and evaluate it using cross-validation.

Web1 dag geleden · @kevin801221, you can integrate your training hyper-parameters with MLflow by modifying the logging functions in train.py.First, import the mlflow library: import mlflow, and then initialize the run before starting the training loop: mlflow.start_run(). When you log your metrics, you can log them to MLflow with mlflow.log_metric(name, value). In machine learning, a hyperparameter is a parameter whose value is used to control the learning process. By contrast, the values of other parameters (typically node weights) are derived via training. Hyperparameters can be classified as model hyperparameters, that cannot be inferred while fitting the machine to the training set because they refer to the model selection task, or algorithm hyper… marmi cantanteWeb24 aug. 2024 · And, scikit-learn’s cross_val_score does this by default.
