Since 2012, Chiba Institute of Technology Planetary Exploration Research Center (hereinafter PERC) has been working on the project called "Project Meteor", where long-term continuous meteor observations using ultra-high-sensitivity CMOS color high-vision cameras from International Space Station (ISS) are made. Actually, it's quite difficult to manually detect the meteor occurrence in the captured video as the duration of meteor illumination is usually less than 1 sec and it's impossible to predict when and where it occurs.

Therefore, STAIR Lab presents you a challenge to develop an algorithm which automatically detects the meteor in the video. The competition is organized by Software Technology and Artificial Intelligence Research Laboratory (hereinafter STAIR Lab) and uses data from PERC.

Task Description

An algorithm should take 3 sec motion video as input and classify it into two groups based on the meteor occurrence. Train set contains 10000 videos whilst test set does 1000 and the number of videos with the meteor occurrence in the train set is 200. The video format is mpg and its resolution is 320 x 180.

High school student department

We've additionally set up a department for high school student.

The task and rules are the same as what are applied to general participants.

Please see the FAQ page for details.

Enforced on April 1, 2018

Submissions are scored on the AUC (Area Under the Curve).


Determination of the final rankings
1. During the competition, scores on the leaderboard are computed based solely on a fraction of the test set. We use the rest of the set to evaluate and determine the final ranking after the competition.
2. If you have the same score with the other participants, the rank will be placed on a first-submit.
Preliminary winners are asked to provide the following items:
- Model source code
　- Pre-trained model
- Model documentation*1 (Execution environment, execution time**1, random seed value*2, feature descriptions and importances*3, modeling approach, insights, and so on)
*1: Give a description of each of the following parts: preprocessing, training, and predicting
*2: Specify it if used
*3: If available
- Questionnaire (motivation for the competition, elapsed time, feedbacks, and so on)
3. When a preliminary winner falls under any of the following, it will lose its eligibility to claim the prize:
- Does not respond to the contact within the prescribed period
- Unable to reproduce the result
- Does not meet the terms or rules
4. When a person is disqualified, its runner-up will be eligible for winning the prize.
