时序建模探索:在之前的方法中,都是利用像素级的扩散,而MagicVideo则是最早采用潜在扩散模型(Latent Diffusion Model,LDM)来进行潜在空间的 T2V 生成的工作之一。通过在低维潜在空间中利用扩散模型,它显著降低了计算复杂性,从而加快了处理速度。引入的逐帧轻量级 adaptor 对齐了图像和视频的分布,使所提出的定向注意力(...

video prediction models 主要技术方案包括:diffusion model、autoregressive model、masked transformer Diffusion model:可以建模连续空间、采集多个样本,但是采样/生成的速度慢 Autoregressive model:训练更容易、对于 context length 更能扩展,但是计算昂贵、predictions suffer from drifting effect (non-stationarity along time...
diffusion models.We begin by discussing existing surveys of vision transformers and comparing them to this work.Then,we review the main components of a vanilla transformer network,including the self-attention mechanism,feed-forward network,position encoding,etc.In the main part of this survey,we ...

Paper Code OD-VAE: An Omni-dimensional Video Compressor for Improving Latent Video Diffusion Model pku-yuangroup/open-sora-plan • • 2 Sep 2024 With the same reconstruction quality, the more sufficient the VAE's compression for videos is, the more efficient the LVDMs are....
The participants' insights along with observations made on their interaction with video games were analyzed through Rogers' Diffusion of Innovation and the General Aggression Model. In summary, the participants, more or less experts in gaming, enjoyed video games and described them as one of their ...
Sparrow failed to grow for another two years. Until a new CEO, Carl Pearson, decided to build up its market share. He did a survey, which showed that consumers who already used Sparrow restaurants were extremely positive about the chain, while customers of other fast-food chains were unwillin...
