Answer: Integrate Hyperopt with Spark MLlib by creating a custom Spark ML estimator and using Hyperopt's fmin function to optimize its hyperparameters.
To perform Bayesian hyperparameter inference for distributed models using Hyperopt, you can create a custom Spark ML estimator that wraps the Spark ML model and its hyperparameters. Then, you can use Hyperopt's fmin function to define the search space and optimize the hyperparameters of the custom estimator. This integration allows you to leverage Hyperopt's capabilities for Bayesian hyperparameter inference while working with distributed models in Spark MLlib.

Given a Spark ML model and a dataset, how would you use Hyperopt to perform Bayesian hyperparameter inference for distributed models? Provide a code snippet that demonstrates the integration of Hyperopt with Spark MLlib for this purpose.
A
Use Hyperopt's fmin function to define the search space and objective function, and then pass the Spark ML model as the objective function to perform Bayesian hyperparameter inference.
B
Integrate Hyperopt with Spark MLlib by creating a custom Spark ML estimator and using Hyperopt's fmin function to optimize its hyperparameters.
C
Hyperopt cannot be used for Bayesian hyperparameter inference in distributed models, as it is designed for single-node models only.
D
Use Spark MLlib's built-in hyperparameter tuning methods instead of Hyperopt, as they are specifically designed for distributed models.
