Weakly supervised learning refers to a variety of studies that attempt to address the challenging pattern recognition tasks by learning from weak or imperfect supervision. Supervised learning methods including Deep Convolutional Neural Networks (DCNNs) have significantly improved the performance in many problems in the field of computer vision, thanks to the rise of large-scale annotated data set and the advance in computing hardware. However, these supervised learning approaches are notorious "data hungry", which makes them are sometimes not practical in many real-world industrial applications. We are often facing the problem that we are not able to acquire enough amount of perfect annotations (e.g., object bounding boxes and pixel-wise masks) for reliable training models. To address this problem, many efforts in so-called weakly supervised learning approaches have been made to improve the DCNNs training to deviate from traditional paths of supervised learning using imperfect data. For instance, various approaches have proposed new loss functions or novel training schemes. Weakly supervised learning is a popular research direction in Computer Vision and Machine Learning communities, many research works have been devoted to related topics, leading to rapid growth of related publications in the top-tier conferences and journals such as CVPR, ICCV, ECCV, T-IP, and T-PAMI. We organize this workshop to investigate current ways of building industry level AI system relying on learning from imperfect data. We hope this workshop will attract attention and discussions from both industry and academic people.
The workshop are expected to deal with data in a weakly supervised manner, which will cover but not limit to the following topics:
Format : Papers are limited to 8 pages, including figures and tables, in the CVPR style. Additional pages containing only cited references are allowed.

*Note: Paper should be prepared in blind-submission review-formatted template.
We will organize the first Learning from Imperfect Data (LID) challenge on object semantic segmentation and scene parsing, which includes two competition tracks（challenge deadline: June 1, 2019）:
In this track, image-level annotations are provided for supervision and the target is performing pixel-level classification. The dataset is built upon the image detection track of ImageNet Large Scale Visual Recognition Competition (ILSVRC). We provide pixel-level annotations of 15K images (validation/testing: 5K/10K) from 200 basic-level categories for evaluation. To the best of our knowledge, this is the most diverse dataset to evaluate the semantic segmentation in the weakly supervised manner.
*Note: The dataset has been updated (raw annotations are added). (2019-05-15)
Beyond object segmentation, background categories such as wall, road, sky need to be further specified for the scene parsing, which is a challenging task compared with object semantic segmentation. Thus, it will be more difficult and expensive to manually annotate pixel-level mask for this task. In this track, we propose to leverage several labeled points that are much easier to obtain to guide the training process.
The dataset is built upon the well-known ADE20K, which includes 20,210 training images from 150 categories. We provide the point-based annotations on the training set. Please download the data from LID Challenge Track2 data .
