質問 37
Which three are unsupervised machine learning algorithms?
- A. Naive Bayes
- B. Principal Component Analysis
- C. Association rule
- D. Logistical Regression
- E. Random Forest
- F. K-means clustering
正解: B,C,F
解説:
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.
