Meta AI Video Similarity Challenge

Descriptor Track: generate useful vector representations of videos
Matching Track: detects which specific clips of a query video correspond to which specific clips in one or more videos in a large corpus of reference videos.

主办方

背景

Manual content moderation has challenges scaling to meet the large volume of content on platforms like Instagram and Facebook, where tens of thousands of hours of video are uploaded each day. Accurate and performant algorithms are critical in flagging and removing inappropriate content. This competition allows you to test your skills in building a key part of that content tracing system, and in so doing contribute to making social media more trustworthy and safe for the people who use it.

Part2时间安排

Phase 1: Model Development (December 2, 2022 00:00 UTC - March 24, 2023 23:59 UTC): Participants have access to the research dataset to develop and refine their models. Submissions may be made to the public leaderboard and evaluated for the Phase 1 leaderboard. These scores will not determine final leaderboard and rankings for prizes.

Phase 2: Final Scoring (April 2, 2023 00:00 UTC to April 9, 2023 23:59 UTC): Participants will have the opportunity to make up to three submissions against a new, unseen test set. Performance against this new test set will be used to determine rankings for prizes.

Part4赛题描述

For the Descriptor Track, your goal is to generate useful vector representations of videos for this video similarity task. You will submit descriptors for both query and reference set videos. A standardized similarity search using pair-wise inner-product similarity will be used to generate ranked video match predictions.
For the Matching Track, your goal is to create a model that directly detects which specific clips of a query video correspond to which specific clips in one or more videos in a large corpus of reference videos. You will submit predictions indicating which portions of a query video are derived from a reference video.
