The Mechanistic Emergence of Symbol Grounding in Language Models
A new research paper explores how language models develop symbol grounding, the ability to connect words with real-world experiences. The study found that this grounding emerges in the middle layers of models, particularly through attention mechanisms that aggregate environmental data to predict linguistic forms. This phenomenon was observed in various multimodal and architectural setups, suggesting it's a generalizable emergent property in large-scale models. AI
