Excited to present two papers at #ICLR2025 in Singapore 🇸🇬! If you are attending, please drop by our posters to talk about diffusion models 🔥 Details in the thread 🧵👇
Excited to share minHiWave, my reimplementation of the HiWave paper! Clean code, minimal setup, and ready to run. Check it out: github.com/laihongphuc/mi…
HiWave Training-Free High-Resolution Image Generation via Wavelet-Based Diffusion Sampling
[LG] Guidance in the Frequency Domain Enables High-Fidelity Sampling at Low CFG Scales S Sadat, T Vontobel, F Salehi, R M. Weber [ETH Zürich & DisneyResearch|Studios] (2025) arxiv.org/abs/2506.19713
Preprint of today: Sadat et al., "Guidance in the Frequency Domain Enables High-Fidelity Sampling at Low CFG Scales" -- arxiv.org/abs/2506.19713 Classifier Free Guidance affects generation differently at different frequencies -- set it to low for low frequency, and high for high!
Preprint of today: Vontobel et al., "HiWave: Training-Free High-Resolution Image Generation via Wavelet-Based Diffusion Sampling" -- arxiv.org/abs/2506.20452 This one also uses wavelets and frequency-dependent guidance. Generate->Invert->Add high-freq details for each part.

Thanks, AK, for sharing our work! Also, feel free to check out our related paper, where we explore how frequency analysis can generally enhance image generation in diffusion models: x.com/Msadat97/statu…
