Shotspotter Patent Enables Advancement in Machine Learning Accuracy

ShotSpotter (Nasdaq: SSTI), a gunshot detection, location and forensic analysis provider, announces the U.S. Patent and Trademark Office (USPTO) has granted the company U.S. Patent No. 10,424,048 entitled "Systems and Methods Involving Creation and/or Utilization of Image Mosaics in Classification of Acoustic Events." ShotSpotter's real-time gunshot detection solution uses a two-step process that employs both machine classification and human review. The system can distinguish with high accuracy whether a loud, impulsive sound detected by its acoustic sensors is a gunshot or a non-gunshot incident, such as fireworks, in less than 60 seconds, according to the company. The innovation behind the patent granted to ShotSpotter covers the conversion of multiple features of the audio event into a set of visual displays that are combined into a single image mosaic. This enables the system to leverage deep learning neural networks that typically identify and classify images, not sounds.
