Language Conditioned Spatial Relation Reasoning for 3D Object Grounding

1 code implementation17 Nov 2022 ShiZhe Chen, Pierre-Louis Guhur, Makarand Tapaswi, Cordelia Schmid, Ivan Laptev

In this work we propose a language-conditioned transformer model for grounding 3D objects and their spatial relations.

Instruction-driven history-aware policies for robotic manipulations

2 code implementations11 Sep 2022 Pierre-Louis Guhur, ShiZhe Chen, Ricardo Garcia, Makarand Tapaswi, Ivan Laptev, Cordelia Schmid

In human environments, robots are expected to accomplish a variety of manipulation tasks given simple natural language instructions.

Learning from Unlabeled 3D Environments for Vision-and-Language Navigation

1 code implementation24 Aug 2022 ShiZhe Chen, Pierre-Louis Guhur, Makarand Tapaswi, Cordelia Schmid, Ivan Laptev

Our resulting HM3D-AutoVLN dataset is an order of magnitude larger than existing VLN datasets in terms of navigation environments and instructions.

Think Global, Act Local: Dual-scale Graph Transformer for Vision-and-Language Navigation

1 code implementation CVPR 2022 ShiZhe Chen, Pierre-Louis Guhur, Makarand Tapaswi, Cordelia Schmid, Ivan Laptev

To balance the complexity of large action space reasoning and fine-grained language grounding, we dynamically combine a fine-scale encoding over local observations and a coarse-scale encoding on a global map via graph transformers.

Airbert: In-domain Pretraining for Vision-and-Language Navigation

2 code implementations ICCV 2021 Pierre-Louis Guhur, Makarand Tapaswi, ShiZhe Chen, Ivan Laptev, Cordelia Schmid

Given the scarcity of domain-specific training data and the high diversity of image and language inputs, the generalization of VLN agents to unseen environments remains challenging.
