QUESTIONS AND ACCURATE ANSWERS
▶ Which of the following statements about data preprocessing are true?
(Multiple choice)
A. Data cleansing is a process of filling in missing values, as well as
detecting and eliminating noise and exceptions.
B. Data dimension reduction aims to simplify data attributes and avoid the
curse of dimensionality.
C. Data standardization aims to reduce noise data and improve model
accuracy by standardizing data.
D. Machine learning tasks generate results in the form of model outputs.
Therefore, model training is more important than data preprocessing. -
