由于本文的主题是 Vector Quantization,而 VQ-Diffusion 的主要贡献是在离散扩散模型方面,VQ 只是获取离散隐空间的手段,所以接下来的部分只稍微阐述一下离散扩散模型的设计思路,至于训练细节和模型改进(Improved VQ-Diffusion)就暂且略过,以免喧宾夺主。 扩散模型的加噪、去噪过程都是针对连续情形而言的,所以我们必须为...
同时,随着硬件设备的升级和算法的优化,VQDM的训练效率和性能也将得到进一步提升。 总之,Vector Quantized Diffusion Model作为一种创新的文本到图像合成方法,具有广泛的应用前景和巨大的发展潜力。通过深入了解其原理、特点以及在实际应用中的优势和挑战,我们可以更好地利用这一技术,推动人工智能在图像生成领域的进一步发展...

A method for color error diffusion using semi-vector quantization is proposed that simplifies error diffusion calculations. When three color separations are used, the two separations with the most visually perceptive color output are co... Z Fan,Steven J. Harrington - US 被引量: 23发表: 1999年...
The method also allows for the use of a small vector halftone threshold array while providing quantized images with fine texture and wide color gamuts. In some embodiments error diffusion is distributed according to vector error diffusion.doi:US20120106835 A1Edgar A. Bernal...

在进行推理时,由于没有输入图像(目标就是要生成图像),因此直接在 latent space 开玩,待 MAE + Diffusion models 自回归地生成所有 tokens 后,再由 VAE 的 Decoder 解码成图像。 那么究竟是如何自回归的呢?上文没有讲到,毕竟训练流程是体现不出来的(就像隔壁 NLP 训练 autoregressive models 一样,在训练过程中是...
