SDM 2015 Workshop on Heterogeneous Learning (Half Day) Overview by Organizers The main objective of this workshop is to bring the attention of researchers to real problems with multiple types of heterogeneities, ranging from online social media analysis, traffic prediction, to the manufacturing process, brain image analysis, etc. Some commonly found heterogeneities include task and domain heterogeneity (as in multi-task learning, domain adaptation), view heterogeneity (as in multi-view learning), instance heterogeneity (as in multi-instance learning), label heterogeneity (as in multi-label learning), oracle heterogeneity (as in crowdsourcing), etc. In the past years, researchers have proposed various techniques for modeling a single type of heterogeneity as well as multiple types of heterogeneities. This workshop focuses on novel methodologies, applications and theories for effectively leveraging these heterogeneities. Here we are facing multiple challenges. To name a few: (1) how can we effectively exploit the label/example structure to improve the classification performance; (2) how can we handle the class imbalance problem when facing one or more types of heterogeneities; (3) how can we improve the effectiveness and efficiency of existing learning techniques for large-scale problems, especially when both the data dimensionality and the number of labels/examples are large; (4) how can we jointly model multiple types of heterogeneities to maximally improve the classification performance; (5) how do the underlying assumptions associated with multiple types of heterogeneities affect the learning methods. We encourage submissions on a variety of topics, including but not limited to: (1) Novel approaches for modeling a single type of heterogeneity, e.g., task/view/instance/label/oracle heterogeneities. (2) Novel approaches for simultaneously modeling multiple types of heterogeneities, e.g., multi-task multi-view learning to leverage both the task and view heterogeneities. (3) Novel applications with a single or multiple types of heterogeneities. (4) Systematic analysis regarding the relationship between the assumptions underlying each type of heterogeneity and the performance of the predictor; For this workshop, the potential participants and target audience would be faculty, students and researchers in related areas, e.g., multi-task learning, multi-view learning, multi-instance learning, multi-label learning, etc. We also encourage people with application background to actively participate in this workshop. We believe that advancements on these topics will benefit a variety of application domains. Format: The proposed workshop will have keynote talks, invited talks, oral/poster presentations from paper authors, and panel/open discussions. Target Audience: Researchers and practitioners working on problems exhibiting multiple types of heterogeneity.

Invited Speakers (Confirmed) Return to Top Vipin Kumar (University of Minnesota) Heng Huang (University of Texas, Arlington) Dinggang Shen (UNC) Shai Ben-David (University of Waterloo) Fei Sha (University of Southern California) Workshop References Return to Top The proposed workshop builds upon the previous edition at SDM 2014 [1], as well as other workshops on transfer learning/domain adaptation [2,3,4,5], crowdsourcing [6,7,8]. The major difference is that, while previous workshops focused on a single type of heterogeneity, the proposed workshop has a broader scope, and encourages submissions on modeling both a single and multiple types of heterogeneities.
