We are pleased to announce the Visual Question Answering (VQA) Challenge 2020. Given an image and a natural language question about the image, the task is to provide an accurate natural language answer. <!--Visual questions selectively target different areas of an image, including background details and underlying context.-->

VQA Challenge 2020 is the fifth edition of the VQA Challenge. Previous four versions of the VQA Challenge were organized in past three years, and the results were announced at VQA Challenge Workshop in CVPR 2019, CVPR 2018, CVPR 2017 and CVPR 2016.

Following <a href="http://mscoco.org/dataset/">COCO</a>, we have divided the test set for VQA v2.0 into a
number of splits, including test-dev, test-standard, test-challenge, and test-reserve, to limit overfitting
while giving researchers more flexibility to test their system. Test-dev is used for debugging and
validation experiments and allows for maximum 10 submissions per day (according to UTC timezone).
Test-standard is the default test data for the VQA competition. When comparing to the state of the art
(e.g., in papers), results should be reported on test-standard. Test-standard is also used to maintain a
public leaderboard that is updated upon submission. Test-reserve is used to protect against possible
overfitting. If there are substantial differences between a method's scores on test-standard and
test-reserve, this will raise a red-flag and prompt further investigation. Results on test-reserve will not
be publicly revealed. Finally, test-challenge is used to determine the winners of the challenge.
</p>
<p style="font-size:15px; font-weight: 400; text-align:left">
The <a href="evaluation.html">evaluation</a> page lists detailed information regarding how submissions will
be scored. The evaluation servers are open. Following last few years, we are hosting the evaluation servers on <a href="https://evalai.cloudcv.org">EvalAI</a>, developed by the <a href="https://cloudcv.org">CloudCV</a>
team. EvalAI is an <a href="https://github.com/Cloud-CV/EvalAI">open-source</a> web platform designed for
organizing and participating in challenges to push the state of the art on AI tasks. We encourage people to first submit to "Test-Dev" phase to make sure that
you understand the submission procedure, as it is identical to the full test set submission procedure. <b>Note
that the "Test-Dev" and "Test-Challenge" evaluation servers do not have public leaderboards.</b>
</p>
<p style="font-size:15px; font-weight: 400; text-align:left">
To <b>enter the competition</b>, first you need to create an account on <a href="https://evalai.cloudcv.org/auth/signup">EvalAI</a>.
<!-- From your account you will be able to participate in all VQA challenges. --> We allow people to enter
our challenge either privately or publicly. Any submissions to the "Test-Challenge" phase will be
considered to be participating in the challenge. For submissions to the "Test-Standard" phase, only ones that
were submitted before the challenge deadline and posted to the public leaderboard will be considered to be
participating in the challenge.
<br>
<br> Before uploading your results to EvalAI, you will need to create a JSON file containing your results
in the correct format as described on the <a href="evaluation.html">evaluation</a> page.
</p>
<p style="font-size:15px; font-weight: 400; text-align:left">
To <b>submit</b> your JSON file to the VQA evaluation servers, click on the “Submit” tab on the <a href="https://evalai.cloudcv.org/web/challenges/challenge-page/514/overview">VQA
Challenge 2020</a> page on EvalAI. Select the phase ("Test-Dev" or "Test-Standard" or "Test-Challenge
"). <b>Please select the JSON file to upload and fill in the required fields such as "method name"
and "method description" and click “Submit”</b>. After the file is uploaded, the evaluation server will
begin processing. To view the status of your submission please go to <a href="https://evalai.cloudcv.org/web/challenges/challenge-page/514/my-submission">“My
Submissions”</a> tab and choose the phase to which the results file was uploaded. Please be patient,
the evaluation may take quite some time to complete
<!--(~1min on test-dev and ~3min on the full test set)--> (~4 min). If the status of your submission is
“Failed” please check your "Stderr File" for the corresponding submission.
</p>
<p style="font-size:15px; font-weight: 400; text-align:left">
After evaluation is complete and the server shows a status of “Finished”, you will have the option to
download your evaluation results by selecting “Result File” for the corresponding submission. The "Result
File" will contain the aggregated accuracy on the corresponding test-split (test-dev split for
"Test-Dev" phase, test-standard and test-dev splits for both "Test-Standard" and "Test-Challenge"
phases). If you want your submission to appear on the public leaderboard, please submit to "Test-Standard" phase
and check the box under "Show on Leaderboard" for the corresponding submission.
</p>
<p style="font-size:15px; font-weight: 400; text-align:left">
Please limit the number of entries to the challenge evaluation server to a reasonable number, e.g., one
entry per paper. To avoid overfitting, the number of submissions per user is limited to 1 upload per day
(according to UTC timezone) and a maximum of 5 submissions per user. It is not acceptable to create
multiple accounts for a single project to circumvent this limit. The exception to this is if a group
publishes two papers describing unrelated methods, in this case both sets of results can be submitted for
evaluation. However, Test-Dev allows for 10 submissions per day.
<!--Please refer to the section on "Test-Dev Best Practices" in the <a href="http://mscoco.org/dataset/#detections-upload">MSCOCO detection challenge</a> page for more information about the test-dev set. -->
</p>
<p style="font-size:15px; font-weight: 400; text-align:left">
<!-- Competitors are recommended but not restricted to train their algorithms on VQA train and val sets. -->
The <a href="download.html">download</a> page contains links to all VQA v2.0 train/val/test images,
questions, and associated annotations (for train/val only). Please specify any and all external data used
for training in the "method description" when uploading results to the evaluation server.
</p>
<p style="font-size:15px; font-weight: 400; text-align:left">
Results must be submitted to the evaluation server by the challenge deadline. Competitors' algorithms will
be evaluated according to the rules described on the <a href="evaluation.html">evaluation</a> page.
Challenge participants with the most successful and innovative methods will be invited to present.
