The model is underfitted and trained on a high quantity of patient records.

The model is underfitted and trained on a low quantity of patient records.

NO.54 You have a dataset with many features that you are using to classify a dependent variable. Because the sample size is small, you are worried about overfitting. Which algorithm is ideal to prevent overfitting?

Decision tree

NO.58 Your dependent variable data is a proportion. The observed range of your data is 0.01 to 0.99. The instrument used to generate the dependent variable data is known to generate low quality data for values close to 0 and close to 1. A colleague suggests performing a logit-transformation on the data prior to performing a linear regression. Which of the following is a concern with this approach?
Definition of logit-transformation
If p is the proportion: logit(p)=log(p/(l-p))

After logit-transformation, the data may violate the assumption of independence.

Noisy data could become more influential in your model.

The model will be more likely to violate the assumption of normality.

Values near 0.5 before logit-transformation will be near 0 after.

Which SQL query provides the Directors’ Firstname, Lastname, the name of their departments, and the average employee’s salary?

SELECT m.Firstname, m.Lastname, d.Name, AVG(e.Saiary) as Dept_avg_Saiary FROM Employee_Table as e LEFT JOIN Department_Table as d on e.Dept = d.Name LEFT JOIN Directorjable as m on d.ID = m.DeptJD GROUP BY m.Firstname, m.Lastname, d.Name

SELECT m.Firstname, m.Lastname, d.Name, AVG(e.Salary) as Dept_avg_Salary FROM Employee_Table as e RIGHT JOIN Departmentjable as d on e.Dept = d.Name INNER JOIN Directorjable as m on d.ID = m.DeptJD GROUP BY d.Name

SELECT m.Firstname, m.Lastname, d.Name, AVG(e.Salary) as Dept_avg_Salary FROM Employee_Table as e RIGHT JOIN Department_Table as d on e.Dept = d.Name INNER JOIN Directorjable as m on d.ID = m.DeptJD GROUP BY e.Salary

NO.60 An organization sells house security cameras and has asked their data scientists to implement a model to detect human feces, as distinguished from animals, so they can alert th customers only when a human gets close to their house.
Which of the following algorithms is an appropriate option with a correct reason?

A decision tree algorithm, because the problem is a classification problem with a small number of features.

k-means, because this is a clustering problem with a small number of features.

Logistic regression, because this is a classification problem and our data is linearly separable.

Neural network model, because this is a classification problem with a large number of features.

NO.61 A big data architect needs to be cautious about personally identifiable information (PII) that may be captured with their new IoT system. What is the final stage of the Data Management Life Cycle, which the architect must complete in order to implement data privacy and security appropriately?

De-Duplicate

Destroy

Detain

Duplicate

Clustering

Linear regression

Polynomial regression

Ridge regression

NO.63 Which of the following sentences is TRUE about the definition of cloud models for machine learning pipelines?

Data as a Service (DaaS) can host the databases providing backups, clustering, and high availability.

Infrastructure as a Service (IaaS) can provide CPU, memory, disk, network and GPU.

Platform as a Service (PaaS) can provide some services within an application such as payment applications to create efficient results.

Software as a Service (SaaS) can provide AI practitioner data science services such as Jupyter notebooks.

NO.64 Which two of the following statements about the beta value in an A/B test are accurate? (Select two.)

The Beta value is the rate of type II errors for the test.

The Beta value is the rate of type I errors for the test.

The statistical power of a test is the inverse of the Beta value, or 1 – Beta.
