In this challenge, the task is to navigate towards a set of objects in indoor scenes based only on visual input. AI2-THOR enables navigation in a set of near-photo-realistic indoor scenes, and we will use this framework for the challenge. The agents that the challenge participants provide receive visual input from THOR and should perform an action based on the visual input.
The challenge has two settings: (1) Discrete (2) Continuous, with separate leader boards and winners for each.
Discrete Navigation: By default, the framework operates in discrete mode. This means that the agent navigates on a predefined grid. The agent is only able to look up and down in 30 degree increments and rotate in 90 degree increments. If an action is issued that pushes the agent into a wall, the agent will remain on the grid, but the lastActionSuccess value will be set to False.
Continuous Navigation: In continuous mode, the agent is free to rotate, look up/down and move in any amount. This allows the agent to collide with walls, move towards an object in fewer steps and rotate with greater precision.
The evaluation score is calculated as the average of the optimum number of actions (ot) over the predicted set of actions (pt) over all the tasks:
If the predicted set of actions do not place the agent in the correct location for a task, the score for that task will be zero. The tasks include finding objects in different configurations of a scene from different starting locations.
The participants should submit a file that includes the taken actions. The code below shows how to use the API. While running against the validation scenes, the target_found() method will never return True. The agent must decide when it has reached the goal and cease performing actions. Once the agent has iterated through all the targets defined in the targets file, you can save the actions to a JSON file and submit to the CodaLab challenge. If submitting to the discrete track, you should name this file submission.json. If submitting to the continious track, the file should be named submission_continuous.json. The file should then be zipped and uploaded:
zip -r submission.zip submission.json
You can submit to both tracks at the same time by zipping both submission files:
zip -r submission.zip submission.json submission_continuous.json
Submissions to the continuous track won't be scored on codalab but instead will evaluated and recorded on the leaderboard on the THOR competition page. If your score doesn't appear there within 1-2 days of submission, please contact us.

Evaluation Criteria before the expiration of the Contest Period. By submitting an entry or entries as instructed above ("Submission"), you agree that your Submission conforms to the Guidelines detailed below. Sponsor may choose to remove any Submission or disqualify you from the Contest if it believes that your Submission fails to conform with the Guidelines. Upon completion of all required entry steps and compliance with the Guidelines, you will automatically receive one entry into the Contest. Eligible participants may enter as one of the following categories of participants:
Individual Entries: If you enter as an individual, you must agree to these Official Rules and complete the entry process as instructed above.
Team Entries: If you enter to represent a team ("Team Leader"), you must agree on behalf of yourself and your team members that everyone on your team has read and agreed to the Official Rules, and that they agree to comply with the terms of this Contest. A Team Leader is solely responsible for obtaining all necessary consents and confirmations from each team member. A team's Submission must be made solely by the Team Leader. If a team is selected as a potential winner, each individual team member may be required to sign the Declaration of Eligibility and Liability/Publicity Release required by Sponsor (or Sponsor's designee) in order to be eligible to potentially win a prize. For any winning team, the prize will be given to the Team Leader who submitted the Submission for the team. Sponsor will have no responsibility thereafter for distribution of the prize to the individual team members.
Limit: LIMIT OF 20 ENTRIES PER INDIVIDUAL OR TEAM PER DAY DURING THE VALIDATION PHASE. LIMIT OF THREE ENTRIES PER INDIVIDUAL OR TEAM DURING THE FINAL TEST PHASE. However, no individual person may obtain more than 100 total entries into the Contest. For example, an individual is not permitted to enter 100 times on behalf of him or herself and then submit additional entries on behalf of his or her team. Likewise, no team may obtain more than 100 total Contest entries.
4. Identity of Entrant: As described above in Section 3, all Submissions must be submitted by the individual entrant for an individual entry or the Team Leader for a team entry. Bulk or automated entries will be disqualified (including entries made using any script, macro, bot, or promotional service). Multiple participants are not permitted to share the same email account. Any attempt to obtain additional entries through fraud, bots, or other illegitimate means will result in disqualification, at Sponsor's sole discretion. If there is a dispute about the identity of the entrant, the associated entries will be declared made by the authorized account holder of the email address associated with the account on which the Submission is made. An "authorized account holder" means the natural person who is assigned to an e-mail address by an Internet access provider, online service provider or other organization (e.g., business, educational institution, etc.) that is responsible for assigning e-mail addresses for the domain associated with the submitted e-mail address. Each potential winner may be required to provide Sponsor with proof that the potential winner is the authorized account holder of the email account associated with the winning entry.
5. Selection and Notification of Winner: On or about July 7th, 2017, Sponsor will evaluate all eligible Submissions for the Multi-Label Video Classification Task, the Multi-Label Action Localization Task, and the Multi-Modal Machine Comprehension Task for the Validation Phase. Submissions for each task will be evaluated separately, with a separate leaderboard and winner for each task. On or about July 7, 2017, Sponsor will evaluate all eligible Submissions for the Final Test Phase Task. Sponsor will score each Submission based on the following criteria ("Scoring Criteria"):
The top scoring Submission for each task will be deemed the potential winner, for a total of 3 potential winners. In the unlikely event of a tie, the winner will be determined by the Submission's score in the following criteria: performance on the validation set. Odds of winning a prize depend on number and quality of eligible entries received. Each potential winner will be notified via email on or about July 7, 2017. To the fullest extent permitted by applicable law, Sponsor may require each potential winner (including all team members if a team is selected as a potential winner) to sign and return, within seven days of being notified, an Affidavit of Eligibility and Liability/Publicity Release in order to claim the prize. If (i) the attempted notification is returned as undeliverable without a forwarding address; (ii) any required documents are not returned within seven days, such as the Affidavit of Eligibility and Liability/Publicity Release; or (iii) if potential winner is otherwise unable to accept the prize as stated, the prize will be forfeited and may be awarded to an alternate winner accordance with the Judging Criteria. Only one alternate winner will be selected for each prize. If, by reason of a print or other error, more prizes are claimed than the number set forth in these Official Rules, an alternate winner will be selected in accordance with the above selection process from among all eligible claimants making purportedly valid claims to award the prizes available. Verification of Potential Winner: EACH POTENTIAL WINNER IS SUBJECT TO VERIFICATION BY SPONSOR, WHOSE DECISIONS ARE FINAL AND BINDING IN ALL MATTERS RELATED TO THE CONTEST. AN ENTRANT IS NOT A PRIZE WINNER UNTIL ENTRANT'S ELIGIBILITY HAS BEEN VERIFIED AND ENTRANT HAS BEEN NOTIFIED THAT VERIFICATION IS COMPLETE AND NO FURTHER ACTION IS NEEDED.
