Researchers have developed a new diagnostic framework to understand how large language models hallucinate by analyzing their self-attention mechanisms. The proposed method, which focuses on the "transport" properties of attention, can distinguish between operators and their transposes, a limitation of previous spectral diagnostics. This new approach uses an asymmetry coefficient to quantify directional information flow and has shown interpretable signal in models up to 8 billion parameters, with predictions validated on hallucination benchmarks.
