OnlineCM: Real-time Consensus Maximization with Missing Values

Bowen Dong, Sihong Xie, Jing Gao, Wei Fan, Philip S. Yu
Conference PapersIn Proceedings of the 15th SIAM International Conference on Data Mining (SDM '15), Vancouver, British Columbia, Canada, Apr. 30-May 2, 2015. [paper] [slides] [poster]

Abstract

Combining predictions from multiple sources or models has been shown to be a useful technique in data mining. For example, in network anomaly detection, multiple detectors’ output have to be combined to obtain the diagnostic decisions. Unfortunately, as data are generated at an increasingly high speed, existing prediction aggregation methods are facing new challenges. First, the high velocity and volume of the data render existing batch mode prediction aggregation algorithms infeasible. Second, due to the heterogeneity, predictions from multiple models or data sources might not be perfectly synchronized, leading to abundant miss- ing values in the prediction stream. We propose OnlineCM, short for Online Consensus Maximization, to address the above challenges. OnlineCM keeps only a minimal yet sufficient footprint for both consensus prediction and missing value imputation over the prediction stream. In particular, we show that the correlations among base models or data sources are sufficient for effective consensus prediction, require small storage and can be updated in an online fashion. Further, we identify a reinforcing relationship between missing value imputation and the consensus predictions, leading to a novel consensus-based missing values imputation method, which in turn makes model correlation estimation more accurate. Experiments demonstrates that OnlineCM achieves aggregated predictions that has close performance to the batch mode consensus maximization algorithm, and outperforms baseline methods significantly in large real world datasets.
