As a class of randomized learner model, stochastic configuration networks (SCNs) have been successfully applied in few data analytics tasks. Given the industrial big modeling tasks, however, original SCNs potentially lead to excessive training time. To this end, article extends hybrid parallel version, termed (HPSCNs). In learning algorithm, two are synchronously constructed. The difference between them is that one employs point-incremental and another adopts block-incremental algorithm....
