NEW QUESTION # 14
Which two statements are true about supervised machine learning?
- A. It is used to extract meaningful insights from raw data to improve data operational efficiency.
- B. The learning process is directed by a previously known dependent attribute or target.
- C. It generally results in predictive models.
- D. There is no previously known result to guide the algorithm in building the model.
- E. It does not specify a target, it can be applied to a population of interest.
Answer: B,C
Explanation:
Explanation
Supervised learning is also known as directed learning. The learning process is directed by a previously known dependent attribute or target. Directed data mining attempts to explain the behavior of the target as a function of a set of independent attributes or predictors. Supervised learning generally results in predictive models. This is in contrast to unsupervised learning where the goal is pattern detection. The building of a supervised model involves training, a process whereby the software analyzes many cases where the target value is already known. In the training process, the model "learns" the logic for making the prediction. For example, a model that seeks to identify the customers who are likely to respond to a promotion must be trained by analyzing the characteristics of many customers who are known to have responded or not responded to a promotion in the past.

NEW QUESTION # 26
Which three are unsupervised machine learning algorithms?
- A. K-means clustering
- B. Association rule
- C. Random Forest
- D. Principal Component Analysis
- E. Naive Bayes
- F. Logistical Regression
Answer: A,B,D
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.
