Online latent variable detection in sensor networks Jimeng Sun, Spiros Papadimitriou, and Christos Faloutsos   View Paper (PDF)   Return to Demo Session 3: XML and Data Streams Abstract Sensor networks attract increasing interest, for a broad range of applications. Given a sensor network, one key issue becomes how to utilize it efficiently and effectively. In particular, how can we detect the underlying correlations (latent variables) among many co-evolving sensor measurements? Can we do it incrementally? We present a system that can (1) collect the measurements from the real wireless sensors; (2) process them in real-time; and (3) determine the correlations (latent variables) among the sensor streams on the fly. ©2006 Association for Computing Machinery
