Generally, it has been found that agreement is good (error has been found to be < 10 % in all stated cases) on the desired operating range with NN models regularly outperforming more traditional regression methods . Usage is also easily accessible and reasonably robust, since no numeric solvers are involved. Speedups of up to a factor of 70 have been reported using this methodology . Although popular, NN shortcut models have not been applied to the efficient calculation of chemical equilibria for reactor design to the degree we propose.
