Improved terrain estimation from spaceborne lidar in tropical peatlands using spatial filtering

open access: yesScience of Remote Sensing, 2023
Tropical peatlands are estimated to hold carbon stocks of 70 Pg C or more as partly decomposed organic matter, or peat. Peat may accumulate over thousands of years into gently mounded deposits called peat domes with a relief of several meters over ...

A Comparison of Root Mean Square Errors on Skeletonization Methods [PDF]

open access: yesInternational Journal of Applied Physics and Mathematics, 2012
Vectorization is the most fundamental operation in interpretation of line drawings and document analysis. There are several reasons for converting image vectorization. Vector data is normally created from existing natural source image like photographs, scanned images.

Decomposition of the mean absolute error (MAE) into systematic and unsystematic components.

open access: yesPLoS ONE, 2023
When evaluating the performance of quantitative models, dimensioned errors often are characterized by sums-of-squares measures such as the mean squared error (MSE) or its square root, the root mean squared error (RMSE).

Moments and root-mean-square error of the Bayesian MMSE estimator of classification error in the Gaussian model [PDF]

open access: yesPattern Recognition, 2014
The most important aspect of any classifier is its error rate, because this quantifies its predictive capacity. Thus, the accuracy of error estimation is critical. Error estimation is problematic in small-sample classifier design because the error must be estimated using the same data from which the classifier has been designed. Use of prior knowledge,

Root mean square error (RMSE) or mean absolute error (MAE): when to use them or not

open access: yesGeoscientific Model Development, 2022
Abstract. The mean absolute error (MAE) and root mean squared error (RMSE) are widely used metrics for evaluating models. Yet, there remains enduring confusion over their use, such that a standard practice is to present both, leaving it to the reader to decide.
