Question
Which of the following about unsupervised learning is most accurate?
Answer Choices:
A. There is no labeled data
B. Unsupervised learning has lower forecasting accuracy as compared to supervised learning
C. Classification is an example of unsupervised learning algorithm
Explanation
In unsupervised learning, the ML program is not given labeled training data. Instead,
inputs are provided without any conclusions about those inputs. In the absence of any
tagged data, the program seeks out structure or inter-relationships in the data. Clustering
is one example of the output of unsupervised ML program while classification is suited for
supervised learning.
