The database of Li et al. (7) is a framework that can be extended and refined by adding the underlying raw experimental data in the database and/or refining the underlying model assumptions.
The study examined data from a series of experiments run independently in countries including the US, Italy, Germany, New Zealand and China, where open air croplands, grasslands and forests are subjected to increased levels of CO2 (usually by adding the gas to the experimental areas through pipes).
The amounts of DNA in each of these experimental conditions were equalised by adding the corresponding empty vector.
Experimental solutions were prepared by adding the appropriate amount of furfural into 20 mL of deionized (DI) water.
The OPERA MP model is robust, with stable performance across training, fivefold CV, and test steps (RMSE of about 50 °C), but the model can be further improved by adding more experimental data from the literature.
It is also possible to continuously extend the data warehouse by adding more experimental data, even in data domains which are not already available in OPTIMAS-DW.
However, the reviewers felt that the manuscript needs to be further strengthened by adding additional experimental evidence in a revised version.
Instead of using the inefficient full factorial DOE, a response surface is constructed initially based on the data on the axial experimental points and updated successively by adding one more experimental point selected using an influence index, until the probability is converged.
What's interesting and innovative here is that Barber's taking something classic and familiar a leather shoe and turning it into something completely new by adding an experimental and customizable touch.
