Resumo
The content explores the DIFFUSION LENS method for analyzing text encoders in Text-to-Image (T2I) models. It delves into the computational mechanisms of text encoders, conceptual combination, memory retrieval, and model failures. The study provides valuable insights into how factors like complexity and syntactic structure impact the encoding process.
The study analyzes two popular T2I models, Stable Diffusion and Deep Floyd, using the DIFFUSION LENS method to gain insights into their text encoder components. Through experiments on conceptual combination and memory retrieval, the authors reveal how common concepts emerge earlier than uncommon ones and how knowledge retrieval is gradual across layers.
The findings suggest that different models exhibit distinct patterns in representing complex prompts and knowledge retrieval processes. The study highlights the importance of understanding text encoders in T2I pipelines for improving model interpretability and performance.
