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

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

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

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