GeoSEAN: Explainable Country-Level Image Geolocation for ASEAN Regions

Jul 13, 2026

This study addresses the challenge of visual geolocation in ASEAN countries, where highly similar urban landscapes hinder accurate and interpretable localization. To tackle this issue, the authors propose the first explainable, nation-level image geolocation framework covering all eleven ASEAN nations. The approach integrates CLIP zero-shot classification with LightGBM and MLP classifiers, and introduces a novel multi-dimensional interpretability pipeline combining CLIP attention rollout, YOLOv8 object detection, and Energy-Based Perturbation Games (EBPG) to uncover the key visual cues driving predictions. Experimental results demonstrate that the MLP model achieves 85.91% accuracy and F1 score on the test set while providing object-level fine-grained interpretability, revealing a notable discrepancy between frequently detected objects and regions receiving high attention weights.

AI for Cultural Heritage Textiles: Fine-Tuned Latent Diffusion for Novel Ulos Motif Synthesis

Jul 06, 2026

This study addresses the limitations of traditional Ulos textile patterns—restricted variety and time-intensive design—which hinder the balance between cultural preservation and contemporary innovation. For the first time, the authors apply fine-tuned latent diffusion models to generate authentic Batak Ulos motifs from Indonesia, optimizing Protogen v3.4 and Stable Diffusion v1.4 on a high-quality dataset. Experimental results demonstrate that Protogen v3.4 substantially outperforms Stable Diffusion v1.4, achieving approximately a 10.5-fold reduction in FID and a two-fold increase in Inception Score. A guidance scale between 5 and 9 emerges as optimal, effectively balancing cultural fidelity with pattern diversity. This work not only enables creative regeneration while preserving cultural symbolism but also systematically elucidates how generation parameters influence the trade-off between fidelity and diversity.
