Learning from Limited and Imperfect Data (L2ID) Challenges
In conjunction with the L2ID Workshop at CVPR 2021
June 20, 2021 (Full Day, Virtual Online)

******************************
CALL FOR PARTICIPATION
As part of the CVPR 2021 L2ID workshop, we have two sets of challenges on weakly supervised learning and multi-domain few-shot classification.
We invite you to participate! Winners will be able to present their works during the workshop.

Localization

Check the rules at https://l2id.github.io/challenge_localization.html

Track 1 - Weakly Supervised Semantic Segmentation
This track targets on learning to perform object semantic segmentation using image-level annotations as supervision.

Track 2 - Weakly supervised product detection and retrieval
Given a photo containing multiple product instances and a user-provided description, the track aims to detect the boxes of each product and retrieve the correct single product image in the gallery.

Track 3 - Weakly-supervised Object Localization
This track targets on making the classification networks be equipped with the ability of object localization.

Track 4 - High-resolution Human Parsing
This track aims to recognize human parts within high-resolution images by learning with low-resolution ones.

Multi-Domain Few Shot Classification
Check the rules at https://l2id.github.io/challenge_classification.html

Track 1 - Cross Domain, small scale
This track calls for the development of cross-domain few-shot learning models starting from multiple sources and with no explicit label overlap between sources and target.

Track 2 - Cross Domain, large scale
In this track additional datasets to both source and target datasets have been added for participants with sufficient compute resources. In addition to the multiple sources, *multiple tasks* from which to draw source data or models are provided.

Track 3 - Cross Domain, larger number of classes
In this track, the “wayness” of few-shot learning is increased, bringing it closer to semi-supervised learning.
