Episodic Transformer for Vision-and-Language Navigation

1 code implementation ICCV 2021 Alexander Pashevich, Cordelia Schmid, Chen Sun

We demonstrate that encoding the history with a transformer is critical to solve compositional tasks, and that pretraining and joint training with synthetic instructions further improve the performance.

Learning visual policies for building 3D shape categories

no code implementations15 Apr 2020 Alexander Pashevich, Igor Kalevatykh, Ivan Laptev, Cordelia Schmid

We then show the success of our visual policies for building arches from different primitives.


Learning to Augment Synthetic Images for Sim2Real Policy Transfer

1 code implementation18 Mar 2019 Alexander Pashevich, Robin Strudel, Igor Kalevatykh, Ivan Laptev, Cordelia Schmid

Policies learned in simulators, however, do not transfer well to real scenes given the domain gap between real and synthetic data.

Modulated Policy Hierarchies

no code implementations30 Nov 2018 Alexander Pashevich, Danijar Hafner, James Davidson, Rahul Sukthankar, Cordelia Schmid

To achieve this, we study different modulation signals and exploration for hierarchical controllers.
