NEW QUESTION 72
You need to predict the sea level in meters for the next 10 years.
Which type of machine learning should you use?
- A. regression
- B. clustering
- C. classification
Answer: A
Explanation:
Section: Describe fundamental principles of machine learning on Azure
Explanation:
In the most basic sense, regression refers to prediction of a numeric target.
Linear regression attempts to establish a linear relationship between one or more independent variables and a numeric outcome, or dependent variable.
You use this module to define a linear regression method, and then train a model using a labeled dataset. The trained model can then be used to make predictions.

NEW QUESTION 73
What is a use case for classification?
- A. predicting how many minutes it will take someone to run a race based on past race times
- B. predicting whether someone uses a bicycle to travel to work based on the distance from home to work
- C. analyzing the contents of images and grouping images that have similar colors
- D. predicting how many cups of coffee a person will drink based on how many hours the person slept the previous night.
Answer: C

NOTE: Each correct selection is worth one point.
- A. telephone voice menus to reduce the load on human resources
- B. a chatbot that provides users with the ability to find answers on a website by themselves
- C. a service that creates frequently asked Questions (FAQ) documents by crawling public websites
- D. a telephone answering service that has a pre-recorder message
Answer: A,B
Explanation:
B: A bot is an automated software program designed to perform a particular task. Think of it as a robot without a body.
C: Automated customer interaction is essential to a business of any size. In fact, 61% of consumers prefer to communicate via speech, and most of them prefer self-service. Because customer satisfaction is a priority for all businesses, self-service is a critical facet of any customer-facing communications strategy.
Incorrect Answers:
D: Early bots were comparatively simple, handling repetitive and voluminous tasks with relatively straightforward algorithmic logic. An example would be web crawlers used by search engines to automatically explore and catalog web content.

Box 1: Model evaluation
The Model evaluation module outputs a confusion matrix showing the number of true positives, false negatives, false positives, and true negatives, as well as ROC, Precision/Recall, and Lift curves.
Box 2: Feature engineering
Feature engineering is the process of using domain knowledge of the data to create features that help ML algorithms learn better. In Azure Machine Learning, scaling and normalization techniques are applied to facilitate feature engineering. Collectively, these techniques and feature engineering are referred to as featurization.
Note: Often, features are created from raw data through a process of feature engineering. For example, a time stamp in itself might not be useful for modeling until the information is transformed into units of days, months, or categories that are relevant to the problem, such as holiday versus working day.
Box 3: Feature selection
In machine learning and statistics, feature selection is the process of selecting a subset of relevant, useful features to use in building an analytical model. Feature selection helps narrow the field of data to the most valuable inputs. Narrowing the field of data helps reduce noise and improve training performance.
