Detection theory<\/b>\u00a0or\u00a0signal detection theory<\/b>\u00a0is a means to quantify the ability to discern between information-bearing patterns (called\u00a0stimulus<\/a>\u00a0in living organisms,\u00a0signal<\/a>\u00a0in machines) and random patterns that distract from the information (called\u00a0noise<\/a>, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).<\/p>\n
