NeRF2Real: Sim2real Transfer of Vision-guided Bipedal Motion Skills using Neural Radiance Fields

no code implementations10 Oct 2022 Arunkumar Byravan, Jan Humplik, Leonard Hasenclever, Arthur Brussee, Francesco Nori, Tuomas Haarnoja, Ben Moran, Steven Bohez, Fereshteh Sadeghi, Bojan Vujatovic, Nicolas Heess

A simulation is then created using the rendering engine in a physics simulator which computes contact dynamics from the static scene geometry (estimated from the NeRF volume density) and the dynamic objects' geometry and physical properties (assumed known).

Learning Transferable Motor Skills with Hierarchical Latent Mixture Policies

no code implementations ICLR 2022 Dushyant Rao, Fereshteh Sadeghi, Leonard Hasenclever, Markus Wulfmeier, Martina Zambelli, Giulia Vezzani, Dhruva Tirumala, Yusuf Aytar, Josh Merel, Nicolas Heess, Raia Hadsell

We demonstrate in manipulation domains that the method can effectively cluster offline data into distinct, executable behaviours, while retaining the flexibility of a continuous latent variable model.

DIViS: Domain Invariant Visual Servoing for Collision-Free Goal Reaching

no code implementations18 Feb 2019 Fereshteh Sadeghi

However, DIViS can directly be deployed on a real robot and is capable of servoing to the user-specified object categories while avoiding collisions in the real world.

Sim2Real Viewpoint Invariant Visual Servoing by Recurrent Control

no code implementations CVPR 2018 Fereshteh Sadeghi, Alexander Toshev, Eric Jang, Sergey Levine

In robotics, this ability is referred to as visual servoing: moving a tool or end-point to a desired location using primarily visual feedback.

Sim2Real View Invariant Visual Servoing by Recurrent Control

no code implementations20 Dec 2017 Fereshteh Sadeghi, Alexander Toshev, Eric Jang, Sergey Levine

To this end, we train a deep recurrent controller that can automatically determine which actions move the end-point of a robotic arm to a desired object.

CAD2RL: Real Single-Image Flight without a Single Real Image

1 code implementation13 Nov 2016 Fereshteh Sadeghi, Sergey Levine

We propose a learning method that we call CAD$^2$RL, which can be used to perform collision-free indoor flight in the real world while being trained entirely on 3D CAD models.

Segment-Phrase Table for Semantic Segmentation, Visual Entailment and Paraphrasing

no code implementations ICCV 2015 Hamid Izadinia, Fereshteh Sadeghi, Santosh Kumar Divvala, Yejin Choi, Ali Farhadi

Next, we show that the association of high-quality segmentations to textual phrases aids in richer semantic understanding and reasoning of these textual phrases.

Incorporating Scene Context and Object Layout into Appearance Modeling

no code implementations CVPR 2014 Hamid Izadinia, Fereshteh Sadeghi, Ali Farhadi

In this paper, we propose a method to learn scene structures that can encode three main interlacing components of a scene: the scene category, the context-specific appearance of objects, and their layout.

Probabilistic Label Trees for Efficient Large Scale Image Classification

no code implementations CVPR 2013 Baoyuan Liu, Fereshteh Sadeghi, Marshall Tappen, Ohad Shamir, Ce Liu

Large-scale recognition problems with thousands of classes pose a particular challenge because applying the classifier requires more computation as the number of classes grows.
