Question 1

A Machine Learning Specialist is attempting to build a linear regression model.






Given the displayed residual plot only, what is the MOST likely problem with the model?


Answer: D
Question 2

A data scientist receives a collection of insurance claim records. Each record includes a claim ID. the final outcome of the insurance claim, and the date of the final outcome.

The final outcome of each claim is a selection from among 200 outcome categories. Some claim records include only partial information. However, incomplete claim records include only 3 or 4 outcome categories from among the 200 available outcome categories. The collection includes hundreds of records for each outcome category. The records are from the previous 3 years.

The data scientist must create a solution to predict the number of claims that will be in each outcome category every month, several months in advance.

Which solution will meet these requirements?


Answer: C
Question 3

A machine learning specialist works for a fruit processing company and needs to build a system that
categorizes apples into three types. The specialist has collected a dataset that contains 150 images for each
type of apple and applied transfer learning on a neural network that was pretrained on ImageNet with this
dataset.
The company requires at least 85?curacy to make use of the model.
After an exhaustive grid search, the optimal hyperparameters produced the following:
68?curacy on the training set
67?curacy on the validation set
What can the machine learning specialist do to improve the system's accuracy?


Answer: B
Question 4

A company wants to conduct targeted marketing to sell solar panels to homeowners. The company wants to use machine learning (ML) technologies to identify which houses already have solar panels. The company has collected 8,000 satellite images as training data and will use Amazon SageMaker Ground Truth to label the data. The company has a small internal team that is working on the project. The internal team has no ML expertise and no ML experience. Which solution will meet these requirements with the LEAST amount of effort from the internal team? 


Answer: B
Question 5

A Data Scientist received a set of insurance records, each consisting of a record ID, the final outcome among
200 categories, and the date of the final outcome. Some partial information on claim contents is also provided,
but only for a few of the 200 categories. For each outcome category, there are hundreds of records distributed
over the past 3 years. The Data Scientist wants to predict how many claims to expect in each category from
month to month, a few months in advance.
What type of machine learning model should be used?


each category to expect from month to month.
month to month.
provided, and forecasting using claim IDs and timestamps for all other categories.
