Topic
The presentation will include a technical discussion of recent algorithmic advances made to address key challenges in text mining and data mining of heterogeneous data sources. Several new areas of algorithmic developments will be discussed, including the use of Mariana, a hybrid Support Vector Machine and Markov Chain Monte Carlo optimization system for automatic text classification, the Inductive Monitoring System and Orca for automatic detection of anomalies in continuous data streams, and "sequenceMiner," a new algorithm based on ideas from bioinformatics that discovers anomalies in discrete sequences. The value of these advances will be shown through the use of Aviation data as well as data from Space Shuttle systems.
