# Dataset Card for TST-ProcTHOR

## Dataset Description

- **Homepage:** [https://tst-vision.epfl.ch](https://tst-vision.epfl.ch)
- **Repository:** [TST official repository](https://github.com)
- **Paper:** [Arxiv](https://arxiv.org)

### Dataset Summary

This custom TST-ProcTHOR dataset is used in research work "Multimodality as Supervision: Self-Supervised Specialization to the Test Environment via Multimodality". 

- `pretrain/` is a multimodal pretraining dataset collected using ProcTHOR environment. It contains RGB images, and 9 additional tokenized modalities. 

- `segmentation/train` is the associated downstream dataset used to finetune TST pretrained models on semantic segmentation tasks. 

- `segmentation/test` contains the test dataset used for evaluation/testing on semantic segmentation task. This data corresponds to samples obtained from the test-space itself.

- `captioning/train` is the associated downstream dataset used to finetune TST pretrained models on captioning task. 

- `captioning/test` contains the test dataset used for evaluation/testing on captioning task. This data corresponds to samples obtained from the test-space itself.

## Dataset Creation

It includes procedurally generated
house-like environments. We use 5 procedurally generated
houses as our test space. Dataset is collected by randomly sample various agent
x, y, z positions and orientations along its axis in the test
space, and collect RGB-D images at these points.

### Source Data

Dataset is collected from ProcTHOR simulator.
