Question

Which of the following is true about RMSE?

• A. It helps to find the square root of a number.
• B. It stands for Rough Mean Square Error.
• C. It helps to determine the accuracy of an AI model.
• D. It is the square root of the sum of test values and predicted values.

Hint:

Tip: Lower RMSE = better predictions; it measures how much your model’s output differs from reality.

Answer 1

The Correct Option is C

RMSE signifies Root Mean Square Error, distinct from Rough Mean Square Error.
It serves as a prevalent metric for quantifying the accuracy of model predictions.
RMSE is computed by taking the square root of the mean of the squared discrepancies between observed and predicted values.
A reduced RMSE value signifies superior model performance, implying predictions are in closer proximity to actual outcomes.
It is not the square root of an arbitrary number; it is specifically tied to prediction errors.
Consequently, RMSE aids in assessing the predictive accuracy of AI or statistical models.
Thus, option (C) is the correct choice.
