OUTLINE • Introduction • ACO classification • Delayed diagnosis data • Data analysis • Conclusion • References
INTRODUCTION • Medical error • Delayed diagnosis • AI on medical diagnosis • Ant colony optimization (ACO)
ACO CLASSIFICATION • Classification rulesIF conditions THEN class
ACO CLASSIFICATION • Six steps:1. An ant selects a path (a rule).2. Prune the rule for higher quality. 3. Update the pheromone intensity.4. Optimal rule is chosen after all ants. 5. Remove cases with this rule.6. Update the dataset.
ACO CLASSIFICATION • Step 1: • Step 2: • Step 3: • Step 6:
DELAYED DIAGNOSIS DATA • Data source: Emergency Department • 7 attributes 1 Class Age Injury TriageConsciousnessBreathBlood pressure PulseBody temperature Doctor’s diagnosis
DELAYED DIAGNOSIS DATA • Coding:X1: Age (1)~30 (2)30~60 (3)60~X2: Injury Triage (1)1st class (2)2nd class (3)3rd classX3: Consciousness (1)Clear (2)To Call (3)To Pain (4)ComaX4: Breath (1)10-24/min.(normal) (2)OtherX5: Blood pressure (1)90-140mmHG (2)OtherX6: Pulse (1)60-100/min (2)OtherX7: Body temperature (1)35.5-37.5℃ (2)OtherY: Doctor’s Diagnosis (1)Delayed (2)Did not delay
DATA ANALYSIS • Accuracy – ACO V.S. BPN:
Rule8: 1 DATA ANALYSIS • Classification Rules: Rule1: consciousness = 2 & breathe = 1 & pulse = 2 2 Rule2: temp = 1 1 Rule3: consciousness = 1 1 Rule4: triage = 1 & breathe = 2 1 Rule5: triage = 1 & age = 2 1 Rule6: age = 3 1 Rule7: consciousness = 3 1 triage = 1 & pulse = 2
CONCLUSION • An online detection support system * construct with php
CONCLUSION • Future study:-> More attributes?-> Routine clinic diagnosis?-> More convenient equipement?-> Different rule sets?-> Meaning behind rules?
