Building a Classification Model
The stages to build a classification model for Coral Bleaching are as follows:
Stage 1 Problem Scoping
Coral bleaching occurs when corals lose their vibrant colours and turn white. However, there is much more to this
phenomenon. The primary cause of coral bleaching is climate change.
Coral bleaching is significant because once corals die, reef ecosystems rarely recover. With fewer surviving corals,
reproduction becomes difficult, leading to the deterioration of entire reef ecosystems, which are vital for both people
and wildlife. Early detection of coral bleaching can help mitigate global disasters and protect marine ecosystems.
Do you believe that such projects help raise awareness about global issues and inspire you to think of innovative
solutions to address them?

Stage 2 Data Acquisition
Relevant datasets are identified, collected, and prepared for analysis. For the coral bleaching project, the dataset
used is from the manuscript titled "Bag of Features (BoF) Based Deep Learning Framework for Bleached
Corals Detection." This dataset is intended for research and experimentation to develop AI models for detecting
bleached corals.
You can download the Coral Bleaching dataset from the following link:

Note, Image Analytics can be added by selecting Image option from Add-ins from Options tab.
The steps for acquiring training dataset are as follows:
Step 1 Open Orange Data Mining Tool and locate the Import Image widget.
Step 2 Drag and drop this widget onto your workflow canvas.
Step 3 Right-click on the Import Image widget on the canvas.
Step 4 Select the Rename option.
Step 5 Enter the new name: Training Data to make it easier to identify the widget's purpose.
Step 6 Double-click the renamed Training Data icon to open its configuration window.
Step 7 Click on the Browse button.
The Select Top Level Directory dialog box appears.
Step 8 Navigate the location containing your training dataset.
Step 9 Click on the Select Folder button.
Step 10 Click the Close button to close the Training Data dialog box.
Stage 3 Data Exploration
Data exploration involves analysing and visualizing the dataset to understand its structure, content, and features.
The goal is to ensure the data is ready for modelling. The steps for data exploration are as follows:
Step 11 Drag and drop the Image Viewer widget onto the canvas.
Step 12 Connect the Training Data to the Image Viewer.
