Robustness via Cross-Domain Ensembles

no code implementations ICCV 2021 Teresa Yeo, Oğuzhan Fatih Kar, Alexander Sax, Amir Zamir

We present a method for making neural network predictions robust to shifts from the training data distribution.

Side-Tuning: A Baseline for Network Adaptation via Additive Side Networks

2 code implementations ECCV 2020 Jeffrey O. Zhang, Alexander Sax, Amir Zamir, Leonidas Guibas, Jitendra Malik

When training a neural network for a desired task, one may prefer to adapt a pre-trained network rather than starting from randomly initialized weights.

Learning to Navigate Using Mid-Level Visual Priors

1 code implementation23 Dec 2019 Alexander Sax, Jeffrey O. Zhang, Bradley Emi, Amir Zamir, Silvio Savarese, Leonidas Guibas, Jitendra Malik

How much does having visual priors about the world (e. g. the fact that the world is 3D) assist in learning to perform downstream motor tasks (e. g. navigating a complex environment)?

Mid-Level Visual Representations Improve Generalization and Sample Efficiency for Learning Visuomotor Policies

1 code implementation31 Dec 2018 Alexander Sax, Bradley Emi, Amir R. Zamir, Leonidas Guibas, Silvio Savarese, Jitendra Malik

This skill set (hereafter mid-level perception) provides the policy with a more processed state of the world compared to raw images.

Gibson Env: Real-World Perception for Embodied Agents

5 code implementations CVPR 2018 Fei Xia, Amir Zamir, Zhi-Yang He, Alexander Sax, Jitendra Malik, Silvio Savarese

Developing visual perception models for active agents and sensorimotor control are cumbersome to be done in the physical world, as existing algorithms are too slow to efficiently learn in real-time and robots are fragile and costly.
