here, for data screening method: “no” refers to the model developed by
the initial dataset obtained from NIST; “post” means that the dataset
used to build the model is consistent with “no”, but only the data
points selected under the pre-screening rules are used for calculatingQ 2. “pre” refers the model with the dataset
after data pre-screening
3.4.3. Comparison with references
The results of comparison between this work and other literatures are
detailed in Table 7. The significant difference from other works is that
our work has a wider range of datasets and varying pressure conditions.
Different from our previous studies and other groups, this work expanded
the types of ILs and the number of relevant data points on the basis of
increasing the pre-screening process for data points. Thus, the
lnη (T ,P ,I )-QSPR model is slightly less
accurate than our previous studies, however, it is more robust than the
previous models, because this model has gone through a rigorous LOIO-CV
model validation method. In addition, the modelling process kind of uses
only the topology of the ILs, which has the advantage of simple, fast
and efficient preliminary calculations of η .
