Organized by QQ Browser.

************************************************************************************
Information feeds has already become an important information resource. Al algorithms are essential for understanding information in multiple modalities. QQ browser, with support from CCF TCMT and top AI conference ACM CIKM, hold the 2021 QQ Browser AI competition. There are two tracks, ‘Multimodal Video Similarity’ and ‘Automated Hyperparameter Optimization’, in this competition. We are looking forward to the great ideas and solutions from industry and academia all around the world.

Task 1 Multimodal Video Similarity: This task provides the anonymized features of 1 million short videos from QQ Browser feeds to train the video embedding model. Then, the video pair similarity scores are computed based on the embedding vectors. The predicted scores are evaluated against human-annotated ground truth using Spearman’s rank correlation.

Task 2 Automated Hyperparameter Optimization: This track aims at automated hyperparameters optimization based on anonymized realistic industrial tasks and datasets. Given the space of all possible hyperparameters' values, a reward could be achieved with a set of hyperparameters in each iteration. The participants are asked to maximize the reward within a given limit of iterations with a hyperparameters optimization algorithm.

Rules of the competition

The Competition is open to all individuals—one account per participant. Competition Organizer, Sponsors, and their respective affiliates, subsidiaries, contractors, agents, judges, and advertising and promotion agencies are not eligible to participate in the public competition. If there is one Tencent employee in your team, your team should be identified as an unofficial team and cannot take the reward in the public competition.

The score will be counted by the team. One individual can only join one team. A team could have at most 3 members. The leader must undertake joint liability for all actions of the team and members. The deadline for team joining, leaving and team name changing is 2:00 UTC+8, September 20.

The winners will be invited for a presentation in CIKM which is one of the top AI international conferences. For the date and submission details of the sharing material, please wait for further notification.
