ActioNet Dataset

[Dataset]

Task-Based Dataset

It is created using AI2-THOR (https://ai2thor.allenai.org/). We have made changes to allow for the customisation of initial scene settings (eg. object state) for some tasks. The edited AI2-THOR can be cloned from https://github.com/SamsonYuBaiJian/ai2thor. The custom scene configurations can be found in ./util/scene_config.py.

Our human annotated dataset can be found in the ./dataset/{collection_instance} folders.

Each data file has the naming convention of ./dataset/{collection_instance}/{task}_{floor_plan}. In each file, there are two lists:

First list: [task, floor_plan]
Second list: [first_action, second_action, ..., last_action]

The ./dataset_info/task_descriptions folder contains the descriptions of the tasks for each collection instance.

The ./dataset_info/user_tasks folder contains the collection instances and tasks that each user is in charge of, for a total of 10 users.

The AI2-THOR agent has a default configuration of grid_size=0.25, meaning that each grid block has the size of 0.25 meters.

Dataset Statistics

Dataset statistics are obtained from running python3 ./util/get_stats.py.

The statistics can be found in ./stats.txt.

System Requirements

Linux (tested on Ubuntu 18.04) for using the custom AI2-THOR Unity build
Python 3.6
External Python libraries: ai2thor, keyboard, opencv-python, pillow
Unity 2018.3.6f1

Script Configurations

You can set configurations for custom directories and AI2-THOR settings in ./settings.txt in the {setting}={setting_choice} format.

actionet_path: Path to ActioNet root directory
ai2thor_build_path: Path to custom AI2-THOR Linux build, from https://github.com/SamsonYuBaiJian/ai2thor, eg. ./ai2thor/unity/Builds/linux.x86_64
target_data_dir_for_frames: Path to folder of data files for creating frames with ./util/replay_and_save_frames.py, eg. ./dataset/1
save_frames_dir: Path to save frames created with ./util/replay_and_save_frames.py
save_augmented_data_dir: Path to save augmented data created with ./util/augment_data.py, eg. ./augmented_dataset
target_augmentation_file: Path to specific data file for data augmentation with ./util/augment_data.py, eg. ./dataset/1/Make coffee_FloorPlan1
random_start: Whether to initialise agent at a random position for data augmentation, eg. True or False
seed: Seed for randomising agent location for data augmentation
width: Width of AI2-THOR frame for data augmentation and saving frames
height: Height of AI2-THOR frame for data augmentation and saving frames

Creating Images from Data

The ./util/replay_and_save_frames.py file is used to replay the actions in the dataset as a series of frames, and save the frames in a chosen directory.

Settings can be found in ./settings.txt.

Some samples can be found in the ./saved_frames and ./augmented_saved_frames folders.

Data Augmentation

Sample data files can be found in the ./augmented_dataset folder. If a data file has 'TeleportFull...' as its first action, it means the agent's starting position was randomised.

The data files that can be augmented are listed in ./augmentable_data_files.txt.

Data files that have hand movements, 'ThrowObject', 'PullObject' or 'PushObject' are not augmentable.
