Figure 1
The figure begins with the text “The models available in the articles reviewed” written on the top left. A downward arrow points the text to a vertical list that contains three text boxes, labeled from top to bottom as “S V M,” “X G Boost,” and “Light G B M.” Between “X G Boost” and “Light G B M,” three horizontally arranged dots are present. A rightward arrow from the “Light G B M” is placed at the bottom. The box in the center labeled “Research Gap” contains three vertically arranged rectangles, labeled from top to bottom as “Lack of parameter optimization,” “Lack of feature selection,” and “The need for more comprehensive models.” A cornered rightward arrow points the center box to a box on the right labeled “Model optimization with the Firefly algorithm,” which contains two rectangles arranged vertically, labeled “Parameter optimization” and “Selection of effective features.”Positioning of the study within the existing landscape.
