AIDE: Agentically Improve Visual Language Model with Domain Experts

no code implementations13 Feb 2025 Ming-Chang Chiu, Fuxiao Liu, Karan Sapra, Andrew Tao, Yaser Jacoob, Xuezhe Ma, Zhiding Yu, Guilin Liu

The enhancement of Visual Language Models (VLMs) has traditionally relied on knowledge distillation from larger, more capable models.

Éclair -- Extracting Content and Layout with Integrated Reading Order for Documents

no code implementations6 Feb 2025 Ilia Karmanov, Amala Sanjay Deshmukh, Lukas Voegtle, Philipp Fischer, Kateryna Chumachenko, Timo Roman, Jarno Seppänen, Jupinder Parmar, Joseph Jennings, Andrew Tao, Karan Sapra

Fully comprehending such documents requires an understanding of their structure -- including formatting, formulas, tables, and the reading order of multiple blocks and columns across multiple pages -- as well as semantic information for detecting elements like footnotes and image captions.

Personalized Federated Learning with First Order Model Optimization

3 code implementations ICLR 2021 Michael Zhang, Karan Sapra, Sanja Fidler, Serena Yeung, Jose M. Alvarez

While federated learning traditionally aims to train a single global model across decentralized local datasets, one model may not always be ideal for all participating clients.

World-Consistent Video-to-Video Synthesis

no code implementations ECCV 2020 Arun Mallya, Ting-Chun Wang, Karan Sapra, Ming-Yu Liu

This is because they lack knowledge of the 3D world being rendered and generate each frame only based on the past few frames.

Transposer: Universal Texture Synthesis Using Feature Maps as Transposed Convolution Filter

no code implementations14 Jul 2020 Guilin Liu, Rohan Taori, Ting-Chun Wang, Zhiding Yu, Shiqiu Liu, Fitsum A. Reda, Karan Sapra, Andrew Tao, Bryan Catanzaro

Specifically, we directly treat the whole encoded feature map of the input texture as transposed convolution filters and the features' self-similarity map, which captures the auto-correlation information, as input to the transposed convolution.
