AI总结:

本研究提出名为VOCs的新型视频预测模型家族,在潜在空间运行且单步预测未来状态折扣分布,无需像素预测和多步推演,更适用于下游控制任务并已开源代码。

摘要:

我们提出了一类用于支撑下游控制任务的新型视频预测模型家族,将其命名为Video Occupancy Models(视频占用模型,简称VOCs)。VOCs在紧凑的潜在空间中运行,因此无需对单个像素进行预测。与以往的潜在空间世界模型不同,VOCs可在单步内直接预测未来状态的折扣分布,无需多步推演。我们证实,在构建用于下游控制的视频预测模型时,这两项特性均具备优势。代码可在github.com/manantomar/video-occupancy-models获取。

英文摘要:

We introduce a new family of video prediction models designed to support downstream control tasks. We call these models Video Occupancy models (VOCs). VOCs operate in a compact latent space, thus avoiding the need to make predictions about individual pixels. Unlike prior latent-space world models, VOCs directly predict the discounted distribution of future states in a single step, thus avoiding the need for multistep roll-outs. We show that both properties are beneficial when building predictive models of video for use in downstream control.
