Weiran Wang is a notable inventor based in Arlington, MA (US), recognized for his contributions to audio event detection technologies. With a total of 2 patents, Wang has made significant strides in the field of audio processing, particularly through his work at Amazon Technologies, Inc.

Latest Patents

Wang's latest patents focus on advanced audio event detection systems. The first patent describes a system that processes audio data into audio feature data, utilizing pre-configured candidate interval lengths to identify regions that may contain audio events. A classifier scores these regions, determining the likelihood that they correspond to a desired audio event. If the score meets a certain threshold, the region is confirmed to include an audio event.

The second patent outlines a system that employs recurrent neural networks to subsample input audio data, creating coarser time-scale data. This data is then upsampled to match the finer time scale of the original audio frames. The resulting frames are scored by a classifier to assess the likelihood of corresponding to an audio event. A composite weighted frame is created by summing the weighted frames and dividing by the cumulative score, providing an overall score that indicates the presence of an audio event in the input data.
