Sample Question: To give you an idea of the quality of our questions, here’s an example from the Data Frame API section of the practice exams: Question: The implementation of linear regression in Spark ML first attempts as to solve the linear regression problem using refer decomposition, but this method does not scale well to large numbers of variables. Which of the following approaches does Spark ML use to distribute the training of a linear regression model large data: A. Singular value decomposition B. Logistic regression C. Spark ML cannot distribute linear regression training D. Least-squares method E. Iterative optimization Correct Answer: E. Iterative optimization Explanation: The statement in the question is partially correct – Spark ML does use the Cholesky decomposition method to solve the linear regression problem when using the ordinary least squares (OLS) solver, but this method does not scale well to large datasets with a large number of variables. To overcome this limitation, Spark ML uses an iterative optimization method known as L-BFGS (Limited-memory Broyden-Fletcher-Goldfarb-Shanno) to solve the linear regression problem. The L-BFGS algorithm can be distributed across multiple nodes in a Spark cluster, allowing it to handle large datasets and large numbers of variables. Therefore, the correct answer to the question is E. Iterative optimization. Singular value decomposition is another method that can be used to solve linear regression problems, but it is not typically used in Spark ML’s implementation of linear regression. Logistic regression is a different type of algorithm that is used for binary classification problems, and Spark ML does not use it to distribute linear regression training. The least-squares method is the method used by the OLS solver in Spark ML, but it is not as scalable as the L-BFGS solver for large datasets.
