Abstract: A streaming neural network video codec that leverages temporal redundancy, processing video frames in a rolling window fashion. By encoding video frames using information from multiple frames and only transmitting essential codewords, the system ensures efficient compression with reduced computational overhead. Resiliency to lost codewords is achieved by training with random masks on one or more codewords so that the decoder is robust to packet losses. These techniques achieved improved compression efficiency and significantly reduces the average operations required per frame, allowing for real-time, high-quality video streaming.

Abstract: A neural network audio codec system and related methods are provided. In one example, a method is provided comprising: obtaining speech audio to be encoded; applying the speech audio to an audio encoder that is part of a neural network audio codec system that includes the audio encoder and an audio decoder. The audio encoder and the audio decoder have been trained in an end-to-end manner. The speech audio is encoded with the audio encoder to generate embedding vectors that represent a snapshot of speech audio attributes over successive timeframes of the raw speech audio, and from the embedding vectors, codeword indices are generated to entries in a codebook. The codeword indices are then transmitted or stored for later retrieval and processing by the audio decoder.

Abstract: Described herein are a system and techniques for detecting whether biometric data provided in an access request is genuine or a replay. In some embodiments, the system uses an machine learning model trained using genuine and replay sample data which is optimized in order to produce a result set in which results for the genuine samples are pulled closer to a genuine center and results for the replay samples are pushed away from the genuine center. Subjecting input biometric data (e.g., an audio sample) to the trained model results in a classification of the input biometric data as genuine or replay, which can then be used to determine whether or not to verify the input biometric data.
