Workshop on Outlier Detection & Description under Data Diversity
will be held in conjunction with KDD 2014
August 24th, 2014 in NYC, USA

--------------------------------------------------------------------------


ODD^2 is a workshop organized in conjunction with the ACM SIGKDD Conference on Knowledge, Discovery, and Data Mining (KDD 2014).

The goal of the workshop is to address outlier mining as a three-fold challenge: outlier detection, outlier description, and outlier modeling under data diversity. The focus of the workshop lies in the quantitative and qualitative analysis of anomalies in heterogeneous data, including temporal, spatial, sequence, graph, and multi-dimensional space anomalies. The topics of detection and description for diverse data are rarely considered in unison, and literature for these tasks is spread over different research communities. The main goal of ODD^2 is to bridge this gap and provide a venue for knowledge exchange between these different research areas for a corroborative union of quantitative and qualitative analyses for the study of outlier mining.

Traditionally, outlier mining and anomaly detection focused on the automatic detection of highly deviating objects. It has been studied for several decades in statistics, machine learning, data mining, and database systems, and led to a lot of insight as well as automated systems for the detection of outliers.

For today's outlier mining applications to be successful, three directions should be addressed: (i) how to create outlier detection models, (ii) how to serve the needs of certain applications with respect to interpretability, and (iii) how to create outlier models that can handle datasets consisting of diverse sources. We remark that those directions are not disjoint, in contrast they are quite intertwined: as the diversity and thus complexity of the data increases, outlier description not only becomes more challenging but also even more necessary.

With diverse set of applications using outlier analysis for data exploration and knowledge discovery, the demand for manual verification and interpretability of outliers is steadily increasing. Examples include applications such as health surveillance, customer segmentation, fraud analysis, or sensor monitoring, where one is particularly interested in why an object seems outlying. We elaborate below with a specific example.

For example consider social media platforms such as Twitter or Facebook. The diversity of data in such platforms is immense; ranging from relations among users (graphs), user demographics (high-dimensional features), user-generated content (text), temporal dynamics (data streams), heterogeneous relational data in the form of likes, shares, tags, and so on. Outliers in those applications often correspond to various types of anomalies ranging from fake celebrities, fake user accounts, (social) malware, page-like-as-a-service, and so on. As a result, it becomes critical to develop outlier models that can work with diverse datasets, provide high quality outlier detection, but also describe the reasons for outlier properties to the human user.
