Key Technical Insights
This section highlights the core technical advancements and strategic choices made in developing the mangosteen ripeness detection system.
CIELAB a* Component
Identified as the Most Critical Feature for Ripeness Detection
Integrated Gradients analysis revealed that the red-green color axis (CIELAB a*) is the primary visual cue for distinguishing ripe from unripe mangosteens. This offers critical interpretability for model decisions.

Semi-ripe & Unripe Precision & Recall
The model achieved perfect classification for 'ripe' mangosteens, which is critical for export quality. Minor misclassifications between 'semi-ripe' and 'unripe' stages (2 samples each) indicate strong differentiation capabilities, consistent with observed overlap in PCA.
Data Augmentation Impact
The use of SMOTE and Gaussian noise successfully mitigated issues of small dataset size and class imbalance. This boosted model generalizability and prevented overfitting, leading to the observed high performance on the test set (total 1515 samples after augmentation).
