Data Set Information:

The classification task of this database is to determine where patients in a postoperative recovery area should be sent to next.  Because hypothermia is a significant concern after surgery (Woolery, L. et. al. 1991), the attributes correspond roughly to body temperature measurements.

Results:
     -- LERS (LEM2): 48% accuracy

Attribute Information:

1. L-CORE (patient's internal temperature in C):
             high (> 37), mid (>= 36 and <= 37), low (< 36)
    2. L-SURF (patient's surface temperature in C):
             high (> 36.5), mid (>= 36.5 and <= 35), low (< 35)
    3. L-O2 (oxygen saturation in %):
             excellent (>= 98), good (>= 90 and < 98),
             fair (>= 80 and < 90), poor (< 80)
    4. L-BP (last measurement of blood pressure):
             high (> 130/90), mid (
