πŸ‘· RL Task: Building Structures

This task is about following natural language instructions to build a target structure without seeing what it should look like at the end. The RL agent observes the environment from a first-person point-of-view and is able to move around and place different colored blocks within a predefined building zone. Its task is provided as a dialog between an Architect and a Builder. Specifically, the dialog is split into two parts: the context utterances defining blocks placed previously, and target utterances defining the rest of the blocks to be placed. At the end of an episode, the RL agent receives a score reflecting how complete is the built structure compared to the ground truth target structure.

Example of builder agent interacting in the 3D blocks environment.

If you are using the training environment consider citing:

πŸ–Š Evaluation

To evaluate agent, we run several environment episodes for each subtask from the hidden part of the IGLU dataset. Each subtask initializes the world with some starting grid and sets and some target grid as target. The metric used is the F1 score where the ground truth is the blocks added or removed and the prediction is the difference between initial world and the snapshot of the building zone at the end of the episode (also a 3d tensor). The episode terminates either when the structure is completed, or when the time limit has been reached. We also let the agent decide when to end an episode (as a separate action). For each task in evaluation set, we run a number of episodes and calculate weighted average of task F1 scores, where weights are equal to the total number of blocks to add or remove.

An example of a task represented by an instruction and a set of blocks to add is shown in the visualization below:

πŸ“… Timeline

  • July: Releasing materials: IGLU framework and baselines code.
  • July 20th - August 1st: Warm-up round! Particiants are invited to get familiar with the competition setup, rules, and evaluation system.
  • 1st August: Competition begins! Participants are invited to start submitting their solutions.
  • 7th October: Submission deadline. Submissions are closed and organizers begin the evaluation process.
  • November: Winners are announced and are invited to contribute to the competition writeup.
  • 2nd-3rd of December: Presentation at NeurIPS 2022 (online/virtual).

During warm-up we will collect feedback from participants and may updates some parts of the competition (e.g., rules, evaluation protocol) based of feedback from participants.

πŸ† Prizes

This prize pool for RL Task is divided as follows:

  • 1st place: $4,000 USD
  • 2nd place: $1,500 USD
  • 3st place: $1,000 USD

Task Winners. For each task, we will evaluate submissions as described in the Evaluation section. The three teams that score highest on this evaluation will receive prizes of \$4,000 USD, \$1,500 USD and \$1,000 USD.

Research prizes. We have reserved $3,500 USD of the prize pool to be given out at the organizers’ discretion to submissions that we think made a particularly interesting or valuable research contribution. If you wish to be considered for a research prize, please include some details on interesting research-relevant results in the README for your submission. We expect to award around 2-5 research prizes in total.
