- Abstract summary: We treat videos as visual tokens and train transformer models to autoregressively predict future tokens.
Our models are pre-trained on a diverse dataset of videos and images comprising over 1 trillion visual tokens.
Our results demonstrate that, despite minimal inductive biases, autoregressive pre-training leads to competitive performance.

- Abstract: We empirically study autoregressive pre-training from videos. To perform our study, we construct a series of autoregressive video models, called Toto. We treat videos as sequences of visual tokens and train transformer models to autoregressively predict future tokens. Our models are pre-trained on a diverse dataset of videos and images comprising over 1 trillion visual tokens. We explore different architectural, training, and inference design choices. We evaluate the learned visual representations on a range of downstream tasks including image recognition, video classification, object tracking, and robotics. Our results demonstrate that, despite minimal inductive biases, autoregressive pre-training leads to competitive performance across all benchmarks. Finally, we find that scaling our video models results in similar scaling curves to those seen in language models, albeit with a different rate. More details at https://brjathu.github.io/toto/

In this paper, we study video in-context learning, where the model starts from an existing video clip and generates diverse potential future sequences.
To achieve this, we provide a clear definition of the task, and train an autoregressive Transformer on video datasets.
We design various evaluation metrics, including both objective and subjective measures, to demonstrate the visual quality and semantic accuracy of generation results.

We propose a novel model that learns a prototypical representation of the full action for each class.
We decompose the video into short clips, where a visual encoder extracts features from each clip independently.
Later, a decoder aggregates together in an online fashion features from all the clips for the final class prediction.

This paper addresses the problem of self-supervised video representation learning from a new perspective -- by video pace prediction.
It stems from the observation that human visual system is sensitive to video pace.
We randomly sample training clips in different paces and ask a neural network to identify the pace for each video clip.
