Information Density

Uniform Information Density (UID) research explores how humans distribute information evenly in language and other modalities, aiming to understand the principles governing efficient communication. Current investigations utilize large language models and various information-theoretic metrics (like entropy and surprisal) to analyze information distribution in text, conversation, and even images, examining its role in authorship attribution, text generation, and cross-linguistic word order. Findings are impacting fields like authorship obfuscation and machine-generated text detection, with UID-based methods showing promise in improving the accuracy and efficiency of these applications.
