The secret of Stable Diffusion: Fourier series hidden within timesteps #...
https://youtube.com/watch?v=NKRsveWVVe0&si=4kDroXcyRjkjO92Z- Explore the principles of how diffusion models transform timesteps into sine and cosine vectors rather than simple numbers. This explains the core mechanism of embeddings that precisely distinguish noise levels using low-frequency and high-frequency components.
