NEW QUESTION 19:
You are evaluating a completed binary classification machine learning model.
You need to use precision as the evaluation metric.
Which visualization should you use?
A. Violin plot
B. Gradient descent
C. Box plot
D. Binary classification confusion matrix
Correct Answer: D
Incorrect Answers:
A: A violin plot is a visual that traditionally combines a box plot and a kernel density plot.
B: Gradient descent is a first-order iterative optimization algorithm for finding the minimum of a function. To find a local minimum of a function using gradient descent, one takes steps proportional to the negative gradient (or approximate gradient) of the function at the current point.
C: A box plot lets you see basic distribution information about your data, such as median, mean, range, and quartiles but doesn\’t show you how your data looks throughout its range.

NEW QUESTION 20:
You are performing feature scaling by using the sci-kit-learn Python library for x.1 x2, and x3 features. Original and scaled data are shown in the following image.
Use the drop-down menus to select the answer choice that answers each question based on the information presented in the graphic. NOTE: Each correct selection is worth one point.
Correct Answer:
Box 1: StandardScaler
The StandardScaler assumes your data is normally distributed within each feature and will scale them such that the distribution is now centered around 0, with a standard deviation of 1.
Example:
All features are now on the same scale relative to one another. Box 2: Min Max Scaler
Notice that the skewness of the distribution is maintained but the 3 distributions are brought into the same scale so that they overlap.
Box 3: Normalizer

NEW QUESTION 22:
You are building a machine learning model for translating English-language textual content into French-language textual content.
You need to build and train the machine learning model to learn the sequence of the textual content.
Which type of neural network should you use?
A. Multilayer Perceptions (MLPs)
B. Convolutional Neural Networks (CNNs)
C. Recurrent Neural Networks (RNNs)
D. Generative Adversarial Networks (GANs)
Correct Answer: C
To translate a corpus of English text to French, we need to build a recurrent neural network (RNN).
Note: RNNs are designed to take sequences of text as inputs or return sequences of text as outputs, or both.
They\’re called recurrent because the network\’s hidden layers have a loop in which the output and cell state from each time step become inputs at the next time step.
This recurrence serves as a form of memory.
It allows contextual information to flow through the network so that relevant outputs from previous time steps can be applied to network operations at the current time step.

NEW QUESTION 23:
You need to consider the underlined segment to establish whether it is accurate.
To transform a categorical feature into a binary indicator, you should make use of the Clean Missing Data module.
Select “No adjustment required” if the underlined segment is accurate. If the underlined segment is inaccurate, select the accurate option.
A. No adjustment is required.
B. Convert to Indicator Values
C. Apply SQL Transformation
D. Group Categorical Values
Correct Answer: B
Explanation:
Use the Convert to Indicator Values module in Azure Machine Learning Studio. The purpose of this module is to convert columns that contain categorical values into a series of binary indicator columns that can more easily be used as features in a machine-learning model.
NEW QUESTION 24:
Note: This question is part of a series of questions that present the same scenario.
Each question in the series contains a unique solution that might meet the stated goals.
Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear on the review screen.
You train a classification model by using a logistic regression algorithm.
You must be able to explain the model\’s predictions by calculating the importance of each feature, both as an overall global relative importance value and as a measure of local importance for a specific set of predictions.
You need to create an explainer that you can use to retrieve the required global and local feature importance values.
Solution: Create a MimicExplainer.
Does the solution meet the goal?
A. Yes
B. No
Correct Answer: B
Instead use Permutation Feature Importance Explainer (PFI).
Note 1: Mimic explainer is based on the idea of training global surrogate models to mimic black box models.
A global surrogate model is an intrinsically interpretable model that is trained to approximate the predictions of any black box model as accurately as possible.
Data scientists can interpret the surrogate model to draw conclusions about the black box model.
Note 2: Permutation Feature Importance Explainer (PFI): Permutation Feature Importance is a technique used to explain classification and regression models.
At a high level, the way it works is by randomly shuffling data one feature at a time for the entire dataset and calculating how much the performance metric of interest changes.
The larger the change, the more important that feature is.
PFI can explain the overall behavior of any underlying model but does not explain individual predictions.

NEW QUESTION 25:
You are in the process of creating a machine-learning model. Your dataset includes rows with null and missing values.
You plan to make use of the Clean Missing Data module in Azure Machine Learning Studio to detect and fix the null and missing values in the dataset.
Recommendation: You make use of the Remove entire row option.
Will the requirements be satisfied?
A. Yes
B. No
Correct Answer: A
Explanation:
Remove entire row: Completely removes any row in the dataset that has one or more missing values. This is useful if the missing value can be considered randomly missing.
Reference: https://docs.microsoft.com/en-us/azure/machine-learning/studio-module-reference/clean-missing-data
NEW QUESTION 26:
HOTSPOT
You have a multi-class image classification deep learning model that uses a set of labeled photographs. You create the following code to select hyperparameter values when training the model.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Box 1: Yes
Hyperparameters are adjustable parameters you choose to train a model that governs the training process itself. Azure Machine Learning allows you to automate hyperparameter exploration in an efficient manner, saving you significant time and resources. You specify the range of hyperparameter values and the maximum number of training runs.
The system then automatically launches multiple simultaneous runs with different parameter configurations and finds the configuration that results in the best performance, measured by the metric you choose. Poorly performing training runs are automatically early terminated, reducing the wastage of computing resources.
These resources are instead used to explore other hyperparameter configurations.
Box 2: Yes
uniform(low, high) – Returns a value uniformly distributed between low and high
Box 3: No
Bayesian sampling does not currently support any early termination policy.
