The key purpose of splitting the dataset into training and test sets is:

a. To speed up the training process

b. To reduce the amount of labeled data needed for evaluating classifier accuracy

c. To estimate how well the learned model will generalize to new data

d. To reduce the number of features we need to consider as input to the learning

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
