The difference between the two models was the design of the input layer . The first model ( henceforth , the diagnostics model DIAG ) took diagnostics as input nodes , whereas the second model ( henceforth , the semantic parameters model SEMANP ) took semantic parameters as input nodes , as presented in detail below . The Diagnostics Model ( DIAG ) : Binary ac-ceptability values of the phrases or sentences formed by the syntactic diagnostics constituted the input nodes for the network ( see above for the SI diagnostics ) . Each syntactic diagnostic provided a binary value ( either 0 or 1 ) to one of the input nodes .
