If you are new to the competition, you can start by following the Competition Quick Start and try the Titanic practice competition.
If you follow the tutorial and submit your predictition, you will be awarded the Beginner tier.

Once you are familiar with creating models through practice competitions, the next step is to challenge tier-only competitions and SOTA.
Please refer to the guidelines for earning tiers here and aim for the higher tiers.

For the purpose of ensuring fairness of the competition, sharing of trained models and analysis results (source code, modeling approaches, strategies, etc.) created using the distributed data with others (except for the same team) is prohibited during the competition holding period.
If the participants of the study group are in the same team or you are joining "practice" competitions, there is no problem, but if not, please note that exchanging information on analysis methods, etc. is prohibited (Redistribution of the data is prohibited, so you need to register as a member).

You can download the data from the "Data" tab that appears at the top of the competition page you wish to join.
Alternatively, you can use the official API command line interface SIGNATE CLI (Beta), which allows you to perform everything from data download to submission on the command line. (This is not available for some competitions)

Some competitions allow the use of external data and some do not.
Please check the rules of the competition you are joining.

In many competitions, data download is only available while the competition is opened, and the data tab will no longer be visible after the competition is over.
In cases where the data can still be downloaded after the competition is over, the competition is restarted in the form of SOTA Challenge.
※ SIGNATE Private Competition users cannot participate in the SOTA Challenge.

Some competitions allow team participation and some do not.For competitions that allow team participation, you can create a team by clicking the "Create Team" button that appears near the submit button.
However, the button will disappear in the competitions whose team creation deadline has passed.

Whether or not team-up function is enabled depends on the competition type. When it comes to the competition where the function is enabled, you can see the Team Up button appearing next to the Submit button. Note those one of the following conditions applies are not allowed to join a team when:

• he or she has already teamed up.
• he or she already belongs to another team.

Please also not that in order for one to join a team, it must

• be a solo participant.

Note that a team should be created for each competition even though it has the same team members.

Within the team creation period, members can be added from the "Edit Team" button on the competition page within the maximum number of team members.
Please note that team creation period and the maximum number of team members vary depending on the competition.

You cannot leave your team once you join it.

You can also submit using the SIGNATE CLI. For details, please see here.

The following situations can be considered as reasons for the submission error:

• Your team have reached maximum allowed submissions per day.
• Your team leader deactivated its account.

When one is participating in a competition as a team leader, deactivating its account will instantly disband the team.
Once your team is disbanded, you will no longer be able to submit predictions to the ongoing competition that you have been participating in.
It would be good to discuss the team activity policy among members to avoid unexpected situations.

Please note deactivating a team member's account does not disband the team as long as it is not leader's.
When all team member's accounts except the leader's are deactivated, the team will be regarded as a solo team.

Please refer to this page for details.

Please refer to the submission format of sample_submit.csv available in the Download Data page. Common causes of errors are as follows:

• Incorrect datetime format
• Containing non-numeric values
• Extra comma at the end of the row
• File size is too large (Limit: 256MB)

Only successful submissions do.

The submit button will not be displayed for competitions that have not started or have finished.
If the submit button is not displayed even though the competition is still in progress, there is a possibility that a separate submission page has been prepared.
In particular, in competitions with multiple divisions, the submit button may be placed on the page of each division so please use the link to each division page placed on the competition page to move to and check the page.

Runtime is a feature used in competitions where you submit not a prediction result file but the model you created and the source code for the inference part.
When you submit a trained model, the algorithm (inference program) will be executed and the inference time and results will be output. The output inference results will be automatically submitted to the evaluation function (an existing submission feature).
In this way, it can be used in a variety of situations, such as when measuring and evaluating inference time as well as accuracy, and when performing LIVE evaluation.
More details can be found here.

The final evaluation will be determined based on the evaluation over a certain period of time after the submission deadline using information which will be public after the competition is over.
While the LIVE evaluation is being performed, "LIVE evaluation in progress" will be displayed at the top of the competition page.
