  • Publication number: 20220101273
    Abstract: Machine learning may be used to forecast an estimated time of restoration (ETR) during a service interruption. To forecast an ETR, the collection of information from the multiple sources may be provided as inputs to a machine learning model, such as a deep long-short term memory recurrent neural network, a predictive model, and/or the like. The machine learning model may be trained to optimize the temporal cost function of sustained service interruptions and forecast ETRs for service interruptions (in minutes). The machine learning model may process data/information in real-time and provide an ETR when inputs are not yet available in the repair/resolution process, and update (reforecast) the ETR in real-time as the inputs late become available.

  • Publication number: 20220101826
    Abstract: A method for estimating an embedding capacity includes receiving, at a deterministic reference encoder, a reference audio signal, and determining a reference embedding corresponding to the reference audio signal, the reference embedding having a corresponding embedding dimensionality. The method also includes measuring a first reconstruction loss as a function of the corresponding embedding dimensionality of the reference embedding and obtaining a variational embedding from a variational posterior. The variational embedding has a corresponding embedding dimensionality and a specified capacity. The method also includes measuring a second reconstruction loss as a function of the corresponding embedding dimensionality of the variational embedding and estimating a capacity of the reference embedding by comparing the first measured reconstruction loss for the reference embedding relative to the second measured reconstruction loss for the variational embedding having the specified capacity.

  • Publication number: 20220103851
    Abstract: Video compression and decompression techniques are disclosed that provide improved bandwidth control for video compression and decompression systems. In particular, video coding and decoding techniques quantize input video in multiple dimensions. According to these techniques, pixel residuals may be generated from a comparison of an array of input data to an array of prediction data. The pixel residuals may be quantized in a first dimension. After the quantization, the quantized pixel residuals may be transformed to an array of transform coefficients. The transform coefficients may be quantized in a second dimension and entropy coded. Decoding techniques invert these processes. In still other embodiments, multiple quantizers may be provided upstream of the transform stage, either in parallel or in cascade, which provide greater flexibility to video coders to quantize data in different dimensions in an effort to balance the competing interest in compression efficiency and quality of reconstructed video.
