Researchers have investigated the relationship between the visual naturalness of images derived from real-world data streams and their transferability to image recognition models. They found that while the Fréchet distance to natural images (FID) predicts accuracy, this correlation is not causal. The study utilized WorldStream, a corpus of diverse time-series data, and demonstrated that local structure, rather than spectral naturalness, is the key factor for transferability. Even with full fine-tuning, the performance gap between these encoded images and structured baselines remained significant. AI
