Correct Answer: B

Shared Context

- Which of the following statements Nowak makes about hierarchical clustering is most accurate? A) Bottom-up hierarchical clustering begins with each observation being its own cluster. B) In divisive hierarchical clustering, the algorithm seeks out the two closest clusters. C) Hierarchical clustering is a supervised iterative algorithm that is used to build a hierarchy of clusters.

Question

Nowak tries to explain the reinforcement learning (RL) algorithm to Kowalski and makes a number of statements about it. The reinforcement learning (RL) algorithm involves an agent that is most likely to:

Answer Choices:

A. perform actions that will minimize costs over time

B. take into consideration the constraints of its environment

C. make use of direct labeled data and instantaneous feedback

Explanation

The reinforcement learning (RL) algorithm involves an agent that will perform actions that will maximize its rewards over time, taking into consideration the constraints of the environment. Unlike supervised learning, reinforcement learning has neither instantaneous feedback nor direct labeled data for each observation.
