質問 20
Which two statements are true about supervised machine learning?
- A. It generally results in predictive models.
- B. It is used to extract meaningful insights from raw data to improve data operational efficiency.
- C. The learning process is directed by a previously known dependent attribute or target.
- D. It does not specify a target, it can be applied to a population of interest.
- E. There is no previously known result to guide the algorithm in building the model.
正解: A,C
解説:
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.
