The Text Uncanny Valley: Non-Monotonic Performance Degradation in LLM Information Retrieval
Researchers discovered that Large Language Models exhibit a U-shaped performance degradation curve when processing text with word-boundary corruption, termed the 'Text Uncanny Valley.' This reveals a critical vulnerability in LLM robustness: performance worsens at moderate corruption levels before improving again at extreme corruption, suggesting models struggle during transitions between word-level and character-level processing modes.
