Comparative heat maps of STH prevalence with white circles indicating geographic locations on latitude-longitude coordinates. (a) Observed STH prevalence based on field data from six sub-districts in Thasala District: (1) Taling Chan, (2) Klai, (3) Thai Buri, (4) Thasala, (5) Moklan, and (6) Don Tako. (b) Predicted STH prevalence generated by the CNN-PCA-ANN model incorporating environmental and spatial features. The color gradient ranges from blue (low prevalence) to red (high prevalence), with the color bar showing prevalence percentages for direct comparison between observed and predicted patterns.
