A structure built from small decision making units is a neural:

  1. Network
  2. Notebook
  3. Nutshell
  4. Napkin
Show answer and solution

Correct answer: A. Network

1. The units each take inputs and give an output. 2. They are linked together in layers. 3. That structure is a neural network. _Source: OpenStax Principles of Data Science, Chapter 7, Neural Networks._

The main purpose of a neural network is to do what with complex data?

  1. Classify it
  2. Compress it
  3. Conceal it
  4. Convert it
Show answer and solution

Correct answer: A. Classify it

1. It sorts inputs into categories. 2. Handwritten digits are the classic example. 3. So it classifies data. _Source: OpenStax Principles of Data Science, Chapter 7, Neural Networks._

A famous training dataset of handwritten digits is used for image processing and:

  1. Machine locking
  2. Machine learning
  3. Machine loading
  4. Machine lettering
Show answer and solution

Correct answer: B. Machine learning

1. It supplies labelled examples. 2. Models train on those examples. 3. So it serves machine learning. _Source: OpenStax Principles of Data Science, Chapter 7, Neural Networks._
