[Select Two] When working with the Watson Assistant service, you are prompted to create intent, entity and dialog. Which of those tasks invokes the machine learning process to start in the background?

A) Intent & B) Entity

The dialog uses the... that are identified in the user's input, plus context from the application, to interact with the user and ultimately provide a useful response.

A) Intents

The dialog uses the ... that are identified in the user's input, plus context from the application, to interact with the user and ultimately provide a useful response.

Visual Recognition uses deep learning, including convolutional neural nets (CNN) to analyze a picture. Which of the following best describes what is meant by deep learning using a CNN approach?

A) It learns by layers; the earlier hidden layers depict only edges and additional layers learn more features as the image is being analyzed.

UIMA stands for Unstructured Information Management Architecture. What is its main purpose?

A) Its main goal is to transform unstructured information to structured information.

Which of the following is a true statement regarding natural language processing (NLP)?

A) NLP is a classification problem.

Inverse document frequency is a key annotator used in which stage of the UIMA pipeline?

A) Question analysis.

What makes a neural net a deep learning network?

A) There are lots of layers known as hidden layers that run further analysis of the data that came through the input layer.

Training a Visual Recognition service to be able to differentiate between objects, is best described by which of the following remarks?

A) Upload both positive and negative images.

[Select Two] How would you go about using two services, the Watson Assistant and the Discovery services, together where one picks up where the other leaves off?

A) You can wire them together in Node-RED & B) You can use one of the Dialog nodes to conditionally jump to the Discovery service using confidence value thresholds.

[Select Two] Why would you want to have more than one Workspace in a single instance of your Watson Assistant?

A) You could use one workspace for regular chit-chat and the second one for the domain-specific business conversations. & B) Each workspace could act as a separate bot or application.

Which of the following is an example of an Intent used in the Watson Assistant service?

A)#turn_on

B) Index

Which of the following best describe what happens during the Question Analysis stage in the UIMA pipeline?

B) It parses the question to extract the major features of the question.

In a conversation world, marketers can no longer rely on the "yell & sell" approach and hope for the best. They need to "chat and listen". Which of the following terms best describes the new challenges that marketing departments face?
