xyz. A. Barra et chi vuole: fare BAM/TAM (hetero-associative neural nets) per cinetica di reazione con coefficiente di Hill positivo. Qui i patterns sono, per esempio in un contesto immunitaro, epitopi a cui legarsi e la rete e' un anticorpo che si lega a piu' epitopi in simultanea, con coefficiente di Hill positivo, cioe' il fatto che si lega ad uno dei tre aumenta la probabilita' che anche gli altri due layers riconoscano i loro rispettivi patterns, che nel linguaggio degli enzimi è allosteria. Nota: nel linguaggio della cinetica di reazione serve come input la concentrazione di cio' che i layers vedono (concentrazione del substrato) e nel linguaggio nostro questa e' banalmente M, cioe' il numero di esempi (cioe' il numero di molecole di quel tipo).
