   “Some of the worthy aſſociators of the county of Suffolk have reſolved, that they would point out every publican within their reſpective pariſhes, as unfit to retain a licence, who did not exert him or herſelf to preſerve good order, and to prevent meetings or clubs, in which ſeditious or treaſonable ſubjects are agitated, being held at his or her houſe."”

   “For example, the pattern associator and the auto associator are two common architectures. The purpose of the pattern associator is to perform paired associate learning; that is, to produce the right output stimulus for a given input stimulus.”
