One reason for the lack of direct detection so far is that the gravitational waves that we expect to be produced in nature are very weak, so that the signals for gravitational waves, if they exist, are buried under noise generated from other sources.
A commonly used technique to reduce the effects of noise is to use coincidence detection to filter out events that do not register on both detectors.
Their paper, entitled "Study of the coincidences between the gravitational wave detectors EXPLORER and NAUTILUS in 2001", is based on a statistical analysis of the results from their detectors which shows that the number of coincident detections is greatest when both of their detectors are pointing into the center of our Milky Way galaxy.

The confirmed observation of gravitational waves would be important further evidence for the validity of general relativity.
Ordinary terrestrial sources would be undetectable, despite their closeness, because of the great relative weakness of the gravitational force.
In November 2002, a team of Italian researchers at the Istituto Nazionale di Fisica Nucleare and the University of Rome produced an analysis of their experimental results that may be further indirect evidence of the existence of gravitational waves.

 KDD-98 Program
Fraud detection is ripe for the application of KDD techniques because of the large volume of data involved and the amount of money lost each year to fraud.
We cover typical fraud detection workflow issues such as realtime vs. offline detection, alert investigation, gathering further information, alert explainability, and actions taken when fraud is still suspected after investigation.
Participants will go away with an understanding of fraud detection work to date, how discovery fits into the larger scheme of fraud detection, and challenges, pitfalls, and open research issues related to fraud detection.
