Exam AWS Certified Machine Learning - Specialty topic 1 question 185 discussion

Exam question from Amazon's AWS Certified Machine Learning - Specialty
Question #: 185
Topic #: 1
[All AWS Certified Machine Learning - Specialty Questions]

A retail company collects customer comments about its products from social media, the company website, and customer call logs. A team of data scientists and engineers wants to find common topics and determine which products the customers are referring to in their comments. The team is using natural language processing (NLP) to build a model to help with this classification.
Each product can be classified into multiple categories that the company defines. These categories are related but are not mutually exclusive. For example, if there is mention of "Sample Yogurt" in the document of customer comments, then "Sample Yogurt" should be classified as "yogurt," "snack," and "dairy product."
The team is using Amazon Comprehend to train the model and must complete the project as soon as possible.
Which functionality of Amazon Comprehend should the team use to meet these requirements?

  • A. Custom classification with multi-class mode
  • B. Custom classification with multi-label mode
  • C. Custom entity recognition
  • D. Built-in models

Selected Answer: B
In multi-label classification, individual classes represent different categories, but these categories are somehow related and are not mutually exclusive. As a result, each document has at least one class assigned to it, but can have more. For example, a movie can simply be an action movie, or it can be an action movie, a science fiction movie, and a comedy, all at the same time. In multi-class classification, each document can have one and only one class assigned to it. The individual classes are mutually exclusive. For example, a movie can be classed as a documentary or as science fiction, but not both at the same time.
