LoGAN: Multilingual Font Localization with Generative Agents

LoGAN is a VLM-based agentic framework designed for few-shot multilingual font localization. It takes a handful of glyphs or logo letters and generates complete character sets across many languages, including CJK, by combining a glyph-level diffusion model, style finetuning, spacing/kerning transfer, and texture expansion. The method outperforms specialized font generators and state‑of‑the‑art image editors in glyph fidelity, style, texture, and kerning consistency on datasets covering more than 27 languages.

When Explanations Cannot Be Read: Measuring and Correcting SHAP and LIME Rendering for Right-to-Left Languages

The paper "When Explanations Cannot Be Read: Measuring and Correcting SHAP and LIME Rendering for Right-to-Left Languages" identifies that standard SHAP and LIME visualizations, designed for left‑to‑right scripts, fail to display attribution values correctly for right‑to‑left languages such as Urdu, Arabic, Persian, and Hebrew. It introduces SHAP‑RTL, a rendering layer that preserves the original attribution values while correcting reading direction, script shaping, and font selection for each language. The authors evaluate SHAP‑RTL on hate‑and‑offensive‑language datasets using TF‑IDF and logistic regression, showing that default rendering yields high character error rates, while SHAP‑RTL maintains correct visualizations across all tested languages.
