Steer Arabic Dialects via Sparse Neuron Manipulation at Inference
July 3, 2026
This study identifies sparse neuron populations in Arabic LLMs that encode dialect-specific features. By amplifying or suppressing these neurons during inference, researchers can steer models toward specific dialects without requiring additional fine-tuning.
