1. A method of automatically providing real-time dosing corrections for an industrial process wherein one or more enzymatic compositions are applied to natural fibers for producing a pulp or paper product, the method comprising:
for each of a plurality of pulp or paper products, developing predictive machine learning models by observing correlations over time between outcomes, associated with fiber surface substrate characterization and fiber quality characterization for the respective pulp or paper product, and various combinations of process inputs, comprising characteristics of a respective enzyme blend;
for a particular pulp or paper product to be produced, using an associated model to select an initial enzyme blend to be applied, and respective dose rates for one or more components thereof, based at least in part on input data comprising an expected fiber surface substrate characterization for the pulp or paper product, and an expected fiber quality characterization for the pulp or paper product;
upon application of the initial enzyme blend and respective dose rates for the one or more components thereof, providing real-time feedback data comprising measured values corresponding to an actual fiber surface substrate characterization and an actual fiber quality characterization; and
dynamically selecting a replacement enzyme blend, and respective dose rates for one or more components thereof, based at least in part on the feedback data; and
applying the selected replacement enzyme blend in place of at least a portion of the initial enzyme blend during the industrial process.
