In this introduction, we’ll provide a step-by-step guide to training models with AWS Sagemaker using the sagemaker R package. A hyperparameter tuning job finds the best version of a model by running many training jobs on your dataset using the algorithm you choose and values for hyperparameters within ranges that you specify. In this step you run an Amazon SageMaker automatic model tuning job to find the best hyperparameters and improve upon the training accuracy obtained in Step 6. amazon_estimator. Machine learning experts can take full control of training and hyperparameter tuning and SQL engine doesn't attempt to discover the optimal preprocessors, algorithms and hyperparameters because ML experts make all the choices. After running this tuner on the training and validation data, it saves the estimator that makes use of the best hyperparameters for the training job it did. Parameters. So SageMaker helps with the tuning part using something known as hyperparameter optimization which is also known as HPO and so with HPO actually uses machine learning to improve that machine. If they are in fact log-scaled, it might take some time for SageMaker to discover that fact. Let’s copy this code into the editor.
