Round 183

Round UUID: 3e834641-ccec-4743-a271-67d876f3c9d7

Prompt:

Classify each reef as either 'Healthy' or 'Stressed' according to these explicit rules:

A. Assign the label 'Stressed' if ANY of the following conditions are met:
  1. AlgalCoverage is 'Extensive' AND BleachingEventsPerYear is 'Constant' or 'Frequent'.
  2. ReefIntegrityScore is 'Very Poor', OR PollutionLevel is 'Critical'.
  3. ObservationDuration is greater than 100 AND (PollutionLevel is 'High' or 'Critical').

B. Otherwise, assign 'Healthy' if ALL these are true:
  1. AlgalCoverage is 'Minimal' or 'Sparse'.
  2. BiodiversityIndex is 'High' or 'Very High'.
  3. BleachingEventsPerYear is not 'Constant'.

C. If neither set of rules above strictly applies, default to 'Stressed' if there are two or more signals of: 'PreviousStressIncidents' not 'None', 'DistantStressIndicators' is 'Confirmed', or 'NearbyHealthyReef' is 'Absent'. Otherwise, default to 'Healthy'.

These rules are designed to maximize accuracy and reduce both false positives and false negatives on this dataset.
