Root Mean Square Error (RMSE) is a performance measure defined as the square root of the expectation of the squared difference between estimated and actual values. It is commonly used in assessing the accuracy of parameter estimates. AI generated definition based on:Developments in Water Science,20...

3. What is Root Mean Squared Error or RMSE RMSE is the standard deviation of the errors which occur when a prediction is made on a dataset. This is the same as MSE (Mean Squared Error) but the root of the value is considered while determining the accuracy of the model...
The square root is a very popular mathematical operation. However, as we explained in Chapter 2, when it comes to calculations with decimal numbers on computers, we have precise procedures only for addition, subtraction, and multiplication. Thus we can evaluate precisely only those expressions that...

To determine the magnitude of the BR signalling effect on each geometric parameter, the variance explained by treatment was quantified (Fig. 2h,i and Methods). Notably, when compared with untreated WT, BL-treated roots had significantly longer cells in all tissues and reduced cell depth in most...

due to the reasons explained in method section. Before calibration, the mean NDVI of healthy cotton from January 1 to March 14 was 0.585 while it was 0.451 for infected cotton. After calibration, this systematical bias was almost removed. As shown in Fig.3b, the NDVI of healthy cotton was...
The objective function (Obj) to be minimized was defined as the root mean square of relative differences between measured and simulated D2O concentration at different locations across the root tissue at different times. $$Obj=\Vert \frac{{({C}_{i,j}^{mes}-{C}_{i,j}^{sim})}^{2}}{...
