Submission Requirements

Each proposal should include the following information:

  • Title of the proposed challenge;
  • Names and affiliations of the organizers (including contact information and a brief biography for each organizer);
  • A summary describing the importance of the challenge topic;
  • A tentative list of researchers or teams who would participate in the Challenge;
  • Challenge website (if already known);
  • Estimated number of participants;
  • Planned data and dates (e.g., data available, submission deadline, results announcement).

The submitted proposal will be reviewed for relevance and significance, by a committee assembled by the challenge and Demo chairs.

For each approved challenge, an overview paper from the organizers and papers from participants can be submitted. The challenge paper submission will follow the same guidelines of the regular paper submission ( Please select the subject areas marked “SS01-SS09” corresponding to your challenge name when submitting your paper. Also note that the deadlines of challenge paper submission/update/rebuttal will be one week later in comparison to the regular papers.

For challenge paper review, it mostly follows the same process of regular papers. The main difference is that from each challenge topic two meta-reviewers will be invited from challenge organizers. The meta-reviewers (challenge organizers) can make the decision recommendation from both the system ranking and technical novelty. The TPC and challenge chairs will also cooperate with challenge organizers to make the final decision of paper acceptance/rejection. The accepted challenge paper will be indexed by IEEE just like the accepted regular paper.

Challenge organizers are invited to submit proposals to SLT Challenge and Demonstration chairs via emails. the chairs are as follows:

  • Jun Du (University of Science and Technology of China) at;
  • Kyu Jeong Han (Amazon) at;
  • Wei Xue (Hong Kong University of Science and Techonology) at

Please don’t hesitate to contact the chairs for any additional questions.
