The Guardian Architecture
The Guardian Architecture
Guardian is an example architecture built using the AIS generic
architecture. It's task is the monitoring of patients in a surgical
intensive-care unit (SICU). Patients in a SICU require the use of
life-support devices wich must be constantly monitored since, changes
in the readings offered by these devices could imply that certain
treatments are required immediatly, or the patient might die. Guardian
was designed to monitor the patient's life signs and readings and
determine if the situation is normal or if the patient is in some kind
of danger. In the later case, Guardian also tries to diagnose the
problem and suggest the best possible course of action. In situations
where a quick answer is required (i.e. there is little time to
deliberate) Guardian provides it by reducing the time it spends doing
less critical monitoring tasks and by returning the most likely
diagnosis, along with an explanation and recommendation for treament.
After the treatment is applied Guardian continues normal monitoring of
the patient to make sure that he returns to a stable condition (i.e.
the treatment was successfull).
Guardian implements several skills as part of its knowledge base. It
has skills for: " classification of perceptual observations
into temporal episodes of known semantic categories (e.g. normal,
high, very high); diagnosis of observed signs based on belief
networks; diagnosis and explanation of observed signs based on
generic system models.
