VideoPoet: A Large Language Model for Zero-Shot Video Generation

ICML 2024oral

We present VideoPoet, a language model capable of synthesizing high-quality video from a large variety of conditioning signals. VideoPoet employs a decoder-only transformer architecture that processes multimodal inputs -- including images, videos, text, and audio. The training protocol follows that…

Scaling Vision Transformers to 22 Billion Parameters

ICML 2023oral

The scaling of Transformers has driven breakthrough capabilities for language models. At present, the largest large language models (LLMs) contain upwards of 100B parameters. Vision Transformers (ViT) have introduced the same architecture to image and video modelling, but these have not yet been suc…

Less Is More: Generating Grounded Navigation Instructions From Landmarks

CVPR 2022poster

We study the automatic generation of navigation instructions from 360-degree images captured on indoor routes. Existing generators suffer from poor visual grounding, causing them to rely on language priors and hallucinate objects. Our MARKY-MT5 system addresses this by focusing on visual landmarks;…

Proper Reuse of Image Classification Features Improves Object Detection

CVPR 2022oral

A common practice in transfer learning is to initialize the downstream model weights by pre-training on a data-abundant upstream task. In object detection specifically,the feature backbone is typically initialized with ImageNet classifier weights and fine-tuned on the object detection task. Recent w…

The Surprising Impact of Mask-Head Architecture on Novel Class Segmentation

ICCV 2021poster

Instance segmentation models today are very accurate when trained on large annotated datasets, but collecting mask annotations at scale is prohibitively expensive. We address the partially supervised instance segmentation problem in which one can train on (significantly cheaper) bounding boxes for a…

Unsupervised Learning of Disentangled Representations from Video

NeurIPS 2017spotlight

We present a new model DRNET that learns disentangled image representations from video. Our approach leverages the temporal coherence of video and a novel adversarial loss to learn a representation that factorizes each frame into a stationary part and a temporally varying component. The disentangle…
