(d) Running time (y axis; seconds) of different deconvolution methods (color coded) for different granularity levels of the reference data (x axis).
X axis, top: the granularity of the reference data, defined as the numbers of single-cell groups within each cell type (each of these groups is represented with a single reference profile).
This paper presents an automated framework that uses overlapping subsets of reference data to systematically derive an informed estimate of the standard enthalpy of formation of chemical species and assess the consistency of the reference data.
The reliability of the models was assessed using the coefficient of determination in validation (R2V) and the ratio of standard deviation of the reference data in the validation set to the standard error of prediction (RPDV).
Performance of the different deconvolution methods (y axis) across varying granularity of the reference data that is given as input to the alternative methods (x axis), for the cell-type simulation (top), cell-subtype simulation (middle) and gradual-change simulation (bottom).
Furthermore, the results showed that increasing the size of the reference data set to a certain amount (N = 1200) reduced the estimation error significantly in terms of root-mean-squared residuals (RMSE).
It is obvious that the evaluation result strongly depends on the quality of the reference data, and that the two methods investigated cannot provide representative reference data for dense forests.
These first evaluations would indicate a good performance of GlobSnow SE products in forests; however, this does not necessarily show up in validations due to the non-representativeness of the reference data.
The ratio of indeno(1,2,3-cd pyrene/[indeno(1,2,3-cd pyrene/[indeno(g,h,i)perylene] for the two biomass boilers was lower than those of the reference data for other burning devices, which can probably be used as an indicator to distinguish the emission of biomass boilers from that of industrial coal-fired boilers and residential stoves.
Positive values indicate that the phase of the reference data (HVD H) was delayed with respect to the test data.
In this equation, the difference from the input data is taken for all three dimensional points after posture conversion of the reference data.
