Question 76

A web-based company wants to improve its conversion rate on its landing page Using a large historical dataset of customer visits, the company has repeatedly trained a multi-class deep learning network algorithm on Amazon SageMaker However there is an overfitting problem training data shows 90% accuracy in predictions, while test data shows 70% accuracy only

The company needs to boost the generalization of its model before deploying it into production to maximize conversions of visits to purchases

Which action is recommended to provide the HIGHEST accuracy model for the company's test and validation data?

Options:

A.

Increase the randomization of training data in the mini-batches used in training.

B.

Allocate a higher proportion of the overall data to the training dataset

C.

Apply L1 or L2 regularization and dropouts to the training.

D.

Reduce the number of layers and units (or neurons) from the deep learning network.

Question 77

An automotive company uses computer vision in its autonomous cars. The company trained its object detection models successfully by using transfer learning from a convolutional neural network (CNN). The company trained the models by using PyTorch through the Amazon SageMaker SDK.

The vehicles have limited hardware and compute power. The company wants to optimize the model to reduce memory, battery, and hardware consumption without a significant sacrifice in accuracy.

Which solution will improve the computational efficiency of the models?

Options:

A.

Use Amazon CloudWatch metrics to gain visibility into the SageMaker training weights, gradients, biases, and activation outputs. Compute the filter ranks based on the training information. Apply pruning to remove the low-ranking filters. Set new weights based on the pruned set of filters. Run a new training job with the pruned model.

B.

Use Amazon SageMaker Ground Truth to build and run data labeling workflows. Collect a larger labeled dataset with the labelling workflows. Run a new training job that uses the new labeled data with previous training data.

C.

Use Amazon SageMaker Debugger to gain visibility into the training weights, gradients, biases, and activation outputs. Compute the filter ranks based on the training information. Apply pruning to remove the low-ranking filters. Set the new weights based on the pruned set of filters. Run a new training job with the pruned model.

D.

Use Amazon SageMaker Model Monitor to gain visibility into the ModelLatency metric and OverheadLatency metric of the model after the company deploys the model. Increase the model learning rate. Run a new training job.

Question 78

A company wants to use machine learning (ML) to improve its customer churn prediction model. The company stores data in an Amazon Redshift data warehouse.

A data science team wants to use Amazon Redshift machine learning (Amazon Redshift ML) to build a model and run predictions for new data directly within the data warehouse.

Which combination of steps should the company take to use Amazon Redshift ML to meet these requirements? (Select THREE.)

Options:

A.

Define the feature variables and target variable for the churn prediction model.

B.

Use the SQL EXPLAIN_MODEL function to run predictions.

C.

Write a CREATE MODEL SQL statement to create a model.

D.

Use Amazon Redshift Spectrum to train the model.

E.

Manually export the training data to Amazon S3.

F.

Use the SQL prediction function to run predictions,

Are these Dumps worth buying?
Fraser Oct 9, 2024
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.
Vienna
I highly recommend them. They are offering exact questions that we need to prepare our exam.
Jensen Oct 9, 2024
That's great. I think I'll give Cramkey a try next time I take a certification exam. Thanks for the recommendation!
Ayesha
They are study materials that are designed to help students prepare for exams and certification tests. They are basically a collection of questions and answers that are likely to appear on the test.
Ayden Oct 16, 2024
That sounds interesting. Why are they useful? Planning this week, hopefully help me. Can you give me PDF if you have ?
Everleigh
I must say that they are updated regularly to reflect the latest exam content, so you can be sure that you are getting the most accurate information. Plus, they are easy to use and understand, so even new students can benefit from them.
Huxley Aug 26, 2024
That's great to know. So, you think new students should buy these dumps?
Question 79

A company is running a machine learning prediction service that generates 100 TB of predictions every day A Machine Learning Specialist must generate a visualization of the daily precision-recall curve from the predictions, and forward a read-only version to the Business team.

Which solution requires the LEAST coding effort?

Options:

A.

Run a daily Amazon EMR workflow to generate precision-recall data, and save the results in Amazon S3 Give the Business team read-only access to S3

B.

Generate daily precision-recall data in Amazon QuickSight, and publish the results in a dashboard shared with the Business team

C.

Run a daily Amazon EMR workflow to generate precision-recall data, and save the results in Amazon S3 Visualize the arrays in Amazon QuickSight, and publish them in a dashboard shared with the Business team

D.

Generate daily precision-recall data in Amazon ES, and publish the results in a dashboard shared with the Business team.
