Abstract

fetched live from OpenAlex

Text-to-Thangka generation requires preserving both semantic accuracy and textural details. Current methods struggle with fine-grained feature extraction, multi-level feature integration, and discriminator overfitting due to limited Thangka data. We present HST-GAN, a novel framework combining parallel hybrid attention with differentiable symmetric augmentation. The architecture features a Parallel Spatial-Channel Attention module (PSCA) for precise localization of deity facial features and ritual object textures, along with a Hierarchical Feature Fusion Network (HLFN) for multi-scale alignment. The framework’s Differentiable Symmetric Augmentation (DiffAugment) dynamically adjusts discriminator inputs to prevent overfitting while improving generalization. On the T2IThangka dataset, HST-GAN achieves an Inception Score of 2.08 and reduces Fréchet Inception Distance to 87.91, demonstrating superior performance over baselines on the Oxford-102 benchmark.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
