Reconstructing Hands in 3D with Transformers

no code implementations8 Dec 2023 Georgios Pavlakos, Dandan Shan, Ilija Radosavovic, Angjoo Kanazawa, David Fouhey, Jitendra Malik

The key to HaMeR's success lies in scaling up both the data used for training and the capacity of the deep network for hand reconstruction.

NIFTY: Neural Object Interaction Fields for Guided Human Motion Synthesis

no code implementations14 Jul 2023 Nilesh Kulkarni, Davis Rempe, Kyle Genova, Abhijit Kundu, Justin Johnson, David Fouhey, Leonidas Guibas

This interaction field guides the sampling of an object-conditioned human motion diffusion model, so as to encourage plausible contacts and affordance semantics.

EPIC Fields: Marrying 3D Geometry and Video Understanding

1 code implementation NeurIPS 2023 Vadim Tschernezki, Ahmad Darkhalil, Zhifan Zhu, David Fouhey, Iro Laina, Diane Larlus, Dima Damen, Andrea Vedaldi

Compared to other neural rendering datasets, EPIC Fields is better tailored to video understanding because it is paired with labelled action segments and the recent VISOR segment annotations.

Combining chest X-rays and electronic health record (EHR) data using machine learning to diagnose acute respiratory failure

1 code implementation27 Aug 2021 Sarah Jabbour, David Fouhey, Ella Kazerooni, Jenna Wiens, Michael W Sjoding

Conclusions: Machine learning models combining chest radiographs and EHR data can accurately differentiate between common causes of acute respiratory failure.

Deep Learning Applied to Chest X-Rays: Exploiting and Preventing Shortcuts

no code implementations21 Sep 2020 Sarah Jabbour, David Fouhey, Ella Kazerooni, Michael W. Sjoding, Jenna Wiens

This paper studies the case of spurious class skew in which patients with a particular attribute are spuriously more likely to have the outcome of interest.

Cross-task weakly supervised learning from instructional videos

2 code implementations CVPR 2019 Dimitri Zhukov, Jean-Baptiste Alayrac, Ramazan Gokberk Cinbis, David Fouhey, Ivan Laptev, Josef Sivic

In this paper we investigate learning visual models for the steps of ordinary tasks using weak supervision via instructional narrations and an ordered list of steps instead of strong supervision via temporal annotations.

Visual Memory for Robust Path Following

no code implementations NeurIPS 2018 Ashish Kumar, Saurabh Gupta, David Fouhey, Sergey Levine, Jitendra Malik

Equipped with this abstraction, a second network observes the world and decides how to act to retrace the path under noisy actuation and a changing environment.

Unifying Map and Landmark Based Representations for Visual Navigation

no code implementations21 Dec 2017 Saurabh Gupta, David Fouhey, Sergey Levine, Jitendra Malik

This works presents a formulation for visual navigation that unifies map based spatial reasoning and path planning, with landmark based robust plan execution in noisy environments.

Factoring Shape, Pose, and Layout from the 2D Image of a 3D Scene

no code implementations CVPR 2018 Shubham Tulsiani, Saurabh Gupta, David Fouhey, Alexei A. Efros, Jitendra Malik

The goal of this paper is to take a single 2D image of a scene and recover the 3D structure in terms of a small set of factors: a layout representing the enclosing surfaces as well as a set of objects represented in terms of shape and pose.
