Scenario: Professor Charles Xavier, the telepathic founder of the X-Men, has initiated the migration of the Xavier Institute’s on-prem infrastructure, as it is nearing its end-of-life. Logan, a Data Scientist on the project, has already preprocessed the training data and now wants to utilize automated machine learning (AutoML) to efficiently iterate through various algorithms. A key requirement is that the data should remain unchanged throughout the process. Question: Which featurization mode should Logan use to train the model while ensuring that AutoML does not modify the data?
