Question 1
Which of the following machine learning algorithms typically uses bagging?
A. IGradient boosted treesB. K-means
C. Random forest
D. Decision tree
Question 2
The implementation of linear regression in Spark ML first attempts to solve the linear regressionproblem using matrix decomposition, but this method does not scale well to large datasets with alarge number of variables.Which of the following approaches does Spark ML use to distribute the training of a linear regressionmodel for large data?
A. Logistic regressionB. Singular value decomposition
C. Iterative optimization
Question 3
A data scientist has produced three new models for a single machine learning problem. In the past,the solution used just one model. All four models have nearly the same prediction latency, but amachine learning engineer suggests that the new solution will be less time efficient during inference.In which situation will the machine learning engineer be correct?
A. When the new solution requires if-else logic determining which model to use to compute eachpredictionB. When the new solution's models have an average latency that is larger than the size of theoriginal model
C. When the new solution requires the use of fewer feature variables than the original model
D. When the new solution requires that each model computes a prediction for every record
E. When the new solution's models have an average size that is larger than the size of the originalmodel
Question 4
A data scientist has developed a machine learning pipeline with a static input data set using SparkML, but the pipeline is taking too long to process. They increase the number of workers in the clusterto get the pipeline to run more efficiently. They notice that the number of rows in the training setafter reconfiguring the cluster is different from the number of rows in the training set prior toreconfiguring the cluster.Which of the following approaches will guarantee a reproducible training and test set for eachmodel?
A. Manually configure the clusterB. Write out the split data sets to persistent storage
C. Set a speed in the data splitting operation
D. Manually partition the input data
Question 5
A data scientist is developing a single-node machine learning model. They have a large number ofmodel configurations to test as a part of their experiment. As a result, the model tuning processtakes too long to complete. Which of the following approaches can be used to speed up the modeltuning process?
A. Implement MLflow Experiment TrackingB. Scale up with Spark ML
C. Enable autoscaling clusters
D. Parallelize with Hyperopt
