It is well known that the success of machine learning methods on visual recognition tasks is highly dependent on access to large labeled datasets. Unfortunately, performance often drops significantly when the model is presented with data from a new deployment domain which it did not see in training, a problem known as dataset shift. The VisDA challenge aims to test domain adaptation methods’ ability to transfer source knowledge and adapt it to novel target domains.
This year’s challenge focuses on Domain Adaptive Pedestrian Re-identification, where the source and target domains have completely different classes (pedestrian IDs). The particular task is to retrieve the pedestrian instances of the same ID as the query image. This problem is significantly different from previous VisDA challenges, where the source and target domains share some overlapping classes. Moreover, ID matching depends on fine-grained details, making the problem harder than before.

For details and instructions on how to participate, please visit the VisDA challenge website, where you can download the datasets and development kits.


Evaluation Criteria

  • The final rank will be determined by the overall accuracy on the target test set. The evaluation metrics used to rank the performance of each team will be mean Average Precision (mAP) and Cumulated Matching Characteristics (CMC) curve. For more details, please see VisDA 2020 challenge.
  • The leaderboard will show your CodaLab username, not your team name. Do not use multiple accounts to submit for one team, and limit the number of submissions to the quota specified in the "Participate" section.
  • The main leaderboard shows the results of adapted models and will be used to determine the final team ranks.
