Machine Learning MCQs
This section focuses on "Machine Learning" in Data Science. These Machine Learning Multiple Choice Questions (MCQ) should be practiced to improve the Data Science skills required for various interviews (campus interview, walk-in interview, company interview), placements, entrance exams and other competitive examinations.

5. A__________ begins by hypothesizing a sentence (the symbol S) and successively predicting lower level constituents until individual preterminal symbols are written.
A. bottow-up parser
B. top parser
C. top-down parser
D. bottom parser

A. System Unit
B. structural units.
C. data units
D. empirical units
View Answer

Explanation: A model of language consists of the categories which does not include structural units.
7. Different learning methods does not include?
A. Introduction
B. Analogy
C. Deduction
D. Memorization
View Answer
Ans : A
Explanation: Different learning methods does not include the introduction.
8. The model will be trained with data in one single batch is known as ?
A. Batch learning
B. Offline learning
C. Both A and B
D. None of the above
View Answer
Ans : C
Explanation: we have end-to-end Machine Learning systems in which we need to train the model in one go by using whole available training data. Such kind of learning method or algorithm is called Batch or Offline learning.
