Question 13

A machine learning specialist is preparing data for training on Amazon SageMaker. The specialist is using one of the SageMaker built-in algorithms for the training. The dataset is stored in .CSV format and is transformed into a numpy.array, which appears to be negatively affecting the speed of the training.

What should the specialist do to optimize the data for training on SageMaker?

Options:

A.

Use the SageMaker batch transform feature to transform the training data into a DataFrame.

B.

Use AWS Glue to compress the data into the Apache Parquet format.

C.

Transform the dataset into the RecordIO protobuf format.

D.

Use the SageMaker hyperparameter optimization feature to automatically optimize the data.

Question 14

A company wants to segment a large group of customers into subgroups based on shared characteristics. The company’s data scientist is planning to use the Amazon SageMaker built-in k-means clustering algorithm for this task. The data scientist needs to determine the optimal number of subgroups (k) to use.

Which data visualization approach will MOST accurately determine the optimal value of k?

Options:

A.

Calculate the principal component analysis (PCA) components. Run the k-means clustering algorithm for a range of k by using only the first two PCA components. For each value of k, create a scatter plot with a different color for each cluster. The optimal value of k is the value where the clusters start to look reasonably separated.

B.

Calculate the principal component analysis (PCA) components. Create a line plot of the number of components against the explained variance. The optimal value of k is the number of PCA components after which the curve starts decreasing in a linear fashion.

C.

Create a t-distributed stochastic neighbor embedding (t-SNE) plot for a range of perplexity values. The optimal value of k is the value of perplexity, where the clusters start to look reasonably separated.

D.

Run the k-means clustering algorithm for a range of k. For each value of k, calculate the sum of squared errors (SSE). Plot a line chart of the SSE for each value of k. The optimal value of k is the point after which the curve starts decreasing in a linear fashion.

Question 15

A data scientist is working on a public sector project for an urban traffic system. While studying the traffic patterns, it is clear to the data scientist that the traffic behavior at each light is correlated, subject to a small stochastic error term. The data scientist must model the traffic behavior to analyze the traffic patterns and reduce congestion.

How will the data scientist MOST effectively model the problem?

Options:

A.

The data scientist should obtain a correlated equilibrium policy by formulating this problem as a multi-agent reinforcement learning problem.

B.

The data scientist should obtain the optimal equilibrium policy by formulating this problem as a single-agent reinforcement learning problem.

C.

Rather than finding an equilibrium policy, the data scientist should obtain accurate predictors of traffic flow by using historical data through a supervised learning approach.

D.

Rather than finding an equilibrium policy, the data scientist should obtain accurate predictors of traffic flow by using unlabeled simulated data representing the new traffic patterns in the city and applying an unsupervised learning approach.

Yes, of course, they are necessary to pass the exam. They give you an insight into the types of questions that could come up and help you prepare effectively.
Ace
No problem! I highly recommend Cramkey Dumps to anyone looking to pass their certification exams. They will help you feel confident and prepared on exam day. Good luck!
Harris Oct 31, 2024
That sounds amazing. I'll definitely check them out. Thanks for the recommendation!
Sarah
Yeah, I was so relieved when I saw that the question appeared in the exam were similar to their exam dumps. It made the exam a lot easier and I felt confident going into it.
Aaliyah Aug 27, 2024
Same here. I've heard mixed reviews about using exam dumps, but for us, it definitely paid off.
