• Question 43:

  Which three are unsupervised machine learning algorithms?

  A. K-means clustering

  B. Principal Component Analysis

  C. Association rule

  D. Naive Bayes

  E. Logistical Regression

  F. Random Forest

  Correct Answer: ABC

  Explanation: Unsupervised machine learning uses a more independent approach, in which a computer learns to identify complex processes and patterns without a human providing close, constant guidance. Unsupervised machine learning involves training based on data that does not have labels or a specific, defined output.To continue the childhood teaching analogy, unsupervised machine learning is akin to a child learning to identify fruit by observing colors and patterns, rather than memorizing the names with a teacher's help. The child would look for similarities between images and separate them into groups, assigning each group its own new label. Examples of unsupervised machine learning algorithms include k-means clustering, principal and independent component analysis, and association rules.

  D. OML provides scalable statistical functions though OML4Py and OML4R.
