Scenario: The Unlimited Class Wrestling Federation (UCWF), founded by Edward Garner, is leveraging Microsoft Azure to enhance its business operations. Currently, the IT team is using Azure Machine Learning Service to automate hyperparameter exploration for a neural network classification model. Edward has instructed the team to define the hyperparameter space using random sampling with the following criteria: Learning rate: Selected from a normal distribution with a mean of 10 and a standard deviation of 3 . Batch size: Must be 16, 32, or 64 . Keep probability: Selected from a uniform distribution within the range of 0.05 to 0.1 . A developer on the project must complete the param_sampling method in Azure Machine Learning’s Python API to tune the hyperparameters accordingly. Question: What value should replace [?] to correctly define batch size in the code snippet below? python from azureml . train . hyperdrive import RandomParameterSampling param_sampling = RandomParameterSampling ({ "learning_rate" : normal ( 10 , 3 ), "batch_size" : [?], "keep_probability" : uniform ( 0.05 , 0.1 ) })
