A ML engineer is trying to determine the correctness of the new open-source implementation *X", of a supervised regression algorithm implementation. R-Square is one of the functional performance metrics used to determine the quality of the model.

Which ONE of the following would be an APPROPRIATE strategy to achieve this goal?

SELECT ONE OPTION

A.

Add 10% of the rows randomly and create another model and compare the R-Square scores of both the model.

B.

Train various models by changing the order of input features and verify that the R-Square score of these models vary significantly.

C.

Compare the R-Square score of the model obtained using two different implementations that utilize two different programming languages while using the same algorithm and the same training and testing data.

D.

Drop 10% of the rows randomly and create another model and compare the R-Square scores of both the models.

SELECT ONE OPTION

A.

Technological singularity

B.

Narrow Al

C.

Super Al

D.

This statement is correct. In general, what is considered Al today may change over time.

C.

This statement is incorrect. What is considered Al today will continue to be Al even as technology evolves and changes.

D.

This statement is correct. In general, today the term Al is utilized incorrectly.
