              CASE STUDY: Classification Model: Coral Bleaching


              The purpose of developing a classification model for early identification of coral bleaching to safeguard marine
              ecosystems.
              What Are Coral Reefs?
              Coral reefs are large underwater structures made up of the skeletons of tiny marine animals called coral polyps.
              These polyps belong to the group of animals known as cnidarians and form symbiotic relationships with algae
              called  zooxanthellae.  The  algae  live  within  the  coral  tissue  and  provide  the  corals  with  food  through
              photosynthesis, giving them their vibrant colours.
