Algorithm for data-agnostic event detection from data streams

Summary

Event detection from data streams (for example, detection of computer breaches or new distant stars) typically involves a labor-intensive preprocessing step by experts, which is slow, error-prone, and expensive. Additionally, many of these events have low intensity signals that are obscured by random noise. This technology uses “Information Annihilation” (IA), a computational method to detect events by comparing two data streams without prior data interpretation. This technology provides a fast, low-cost method of event detection from any form of data stream, including low intensity data. Such high-sensitivity signal processing has wide applications in many fields, including bioinformatics, astrophysics, communications, and computer security.

Technology Benefits

Applicable to any form of data stream and is useful across many fieldsHigh sensitivityFastRuns in linear time, so applicable to real-time processingDoes not require expert pre-processingReduces human error in data interpretationIdentifies low intensity eventsCan be embedded on a chipPatent Information:Patent Pending (US 20150242469)Tech Ventures Reference: IR CU16056
