Thread-Efficient Decoding for Neural Texture Compression

Thread‑Efficient Decoding for Neural Texture Compression proposes a shared decoder MLP architecture trained with a gradual decoder freezing schedule and texture clustering to reduce GPU thread divergence by 25‑52%. The method preserves rendering quality while achieving up to 8.48× speedup on a Radeon RX 9070 XT compared to non‑shared baselines. Experiments on over 500 textures and multiple real rendering scenes validate the performance gains and provide comprehensive ablation studies.

Know, then Draw: A New Learning Paradigm for Visual Generation

The paper introduces a new learning paradigm for visual generation that separates knowledge acquisition and high-fidelity rendering. Autoregressive pretraining is used to acquire semantic knowledge, while diffusion models are employed afterward for detailed image synthesis. The authors demonstrate that this approach improves learning efficiency and final generation quality, and they provide compute‑optimal scaling laws that enable training a 3B‑parameter text‑to‑image model with only 6,600 H100 GPU‑hours, achieving state‑of‑the‑art scores on GenEval and DPG‑Bench.
