RMSE
A commonly used statistical metric for measuring the deviation between predicted values and true values. It is widely used as an accuracy evaluation standard in positioning and regression tasks.

Score questions correspond to regression tasks or ordinal classification, and their evaluation metrics focus on MAE, RMSE, or the Spearman correlation coefficient rather than accuracy.
In the LinuxArena experiments, the conventional control setup BashArena predicted deployment safety with a root mean square error (RMSE) of 10.1 percentage points (at a 5% audit budget and under five monitor conditions).
Simulated control evaluations (SCEs) predicted safety with a root mean square error of 3.6 percentage points (at a 5% audit budget and under five monitor conditions), compared with 10.1 percentage points for BashArena.
On the training samples, the character regression model achieved an RMSE of 0.09 and an R² of 0.85.
In recommendation scenarios, models typically use Root Mean Square Error (RMSE) to measure the error between predicted ratings and actual ratings.
Smoothing metrics such as RMSE and absolute error work well for smooth variables like temperature but are unsuitable for highly skewed variables like precipitation, making it difficult for models to predict sporadic events such as heat waves, cyclones, and extreme precipitation.
When evaluating stock price predictions, directional accuracy and backtested returns are more meaningful than MSE or RMSE; a model with a very low RMSE but only 50% directional accuracy is ineffective or even loss-making in live trading.
