Emu Video: Factorizing Text-to-Video Generation by Explicit Image Conditioning

no code implementations17 Nov 2023 Rohit Girdhar, Mannat Singh, Andrew Brown, Quentin Duval, Samaneh Azadi, Sai Saketh Rambhatla, Akbar Shah, Xi Yin, Devi Parikh, Ishan Misra

We present Emu Video, a text-to-video generation model that factorizes the generation into two steps: first generating an image conditioned on the text, and then generating a video conditioned on the text and the generated image.

ImageBind: One Embedding Space To Bind Them All

1 code implementation CVPR 2023 Rohit Girdhar, Alaaeldin El-Nouby, Zhuang Liu, Mannat Singh, Kalyan Vasudev Alwala, Armand Joulin, Ishan Misra

We show that all combinations of paired data are not necessary to train such a joint embedding, and only image-paired data is sufficient to bind the modalities together.

OmniMAE: Single Model Masked Pretraining on Images and Videos

1 code implementation CVPR 2023 Rohit Girdhar, Alaaeldin El-Nouby, Mannat Singh, Kalyan Vasudev Alwala, Armand Joulin, Ishan Misra

Furthermore, this model can be learned by dropping 90% of the image and 95% of the video patches, enabling extremely fast training of huge model architectures.

Omnivore: A Single Model for Many Visual Modalities

2 code implementations CVPR 2022 Rohit Girdhar, Mannat Singh, Nikhila Ravi, Laurens van der Maaten, Armand Joulin, Ishan Misra

Prior work has studied different visual modalities in isolation and developed separate architectures for recognition of images, videos, and 3D data.

Early Convolutions Help Transformers See Better

1 code implementation NeurIPS 2021 Tete Xiao, Mannat Singh, Eric Mintun, Trevor Darrell, Piotr Dollár, Ross Girshick

To test whether this atypical design choice causes an issue, we analyze the optimization behavior of ViT models with their original patchify stem versus a simple counterpart where we replace the ViT stem by a small number of stacked stride-two 3*3 convolutions.

Fast and Accurate Model Scaling

4 code implementations CVPR 2021 Piotr Dollár, Mannat Singh, Ross Girshick

This leads us to propose a simple fast compound scaling strategy that encourages primarily scaling model width, while scaling depth and resolution to a lesser extent.
