  • Publication number: 20240111439
    Abstract: A data service implements a configurable data compressor/decompressor using a recipe generated for a particular data set type and using compression operators of a common registry (e.g., pantry) that are referenced by the recipe, wherein the recipe indicates at which nodes of a compression graph respective ones of the compression operators of the registry are to be implemented. The configurable data compressor/decompressor provides a customizable framework for compressing data sets of different types (e.g., belonging to different data domains) using a common compressor/decompressor implemented using a common set of compression operators.

  • Publication number: 20230230657
    Abstract: Systems and methods of storing and retrieving K-mer data in a data structure are provided. In certain embodiments, the K-mer data is stored as an integer value that defines an address of a slot in the data structure. In many embodiments, each slot in the data structure stores the remaining portion of the K-mer that is not part of the prefix. Additional embodiments are directed to genetic or genomic analysis using a data structure for storing K-mer data.

  • Publication number: 20220417291
    Abstract: Systems and method for video communication using text-based compression in accordance with embodiments of the invention are illustrated. One embodiment includes a method for video communication using text-based compression, where the method includes receiving a file comprising captured audio-video content, encoding captured audio-video content to a text transcript using an encoder, transmitting initialization data, and the text transcript to a decoder, initializing a facial animation model and a text-to-speech (TTS) system using the initialization data, and reconstructing an animated version of the captured audio-video content using the text transcript, the facial animation model and the TTS system at the decoder.

  • Publication number: 20220190842
    Abstract: A lossy compression algorithm is described for performing data compression of high-frequency floating point time-series data, for example. The compression algorithm utilizes a prediction engine that employs at least one of a linear prediction model or a non-linear prediction model to calculate one-step-ahead prediction of a current data value at current sampling time t using N previous quantized data values, where N is the model order. A prediction error is determined between the predicted value and an actual value, and the prediction error is quantized. A quantized current data value is determined from the predicted value and the quantized prediction error. The quantized prediction error is sent from an edge device to a data decompressor on a cloud device. The decompressor reconstructs the quantized current data value using the received quantized prediction error and by generating the same predicted value as the compressor.

  • Publication number: 20200058379
    Abstract: Embodiments of the invention are generally directed to compressing genetic sequencing data. In many embodiments, the genetic sequencing data is reordered and encoded based on sequence homology between individual sequencing reads within the genetic sequencing data. Several embodiments are directed to systems to compress genetic sequencing data, and some embodiments are directed to non-transitory, machine-readable media that direct a processor to compress genetic sequencing data. In further embodiments, the genetic sequencing data represents paired-end sequencing data, and several embodiments transmit the data to a remote device.

  • Patent number: 8219890
    Abstract: Systems and methods are disclosed for denoising for a finite input, general output channel. In one aspect, a system is provided for processing a noisy signal formed by a noise-introducing channel in response to an error correction coded input signal, the noisy signal having symbols of a general alphabet. The system comprises a denoiser and an error correction decoder. The denoiser generates reliability information corresponding to metasymbols in the noisy signal based on an estimate of the distribution of metasymbols in the input signal and upon symbol transition probabilities of symbols in the input signal being altered in a quantized signal. A portion of each metasymbol provides a context for a symbol of the metasymbol. The quantized signal includes symbols of a finite alphabet and is formed by quantizing the noisy signal. The error correction decoder performs error correction decoding on noisy signal using the reliability information generated by the denoiser.

  • Patent number: 7971131
    Abstract: Systems and methods for iterative denoising and error correction decoding are presented. In an embodiment, a system iteratively processes a noisy signal formed by a noise-introducing channel in response to an error correction coded input signal. A denoiser generates reliability information for symbols in the input signal. The reliability information is generated by forming a product of received reliability information and an estimate of the distribution of metasymbols in the input signal, each metasymbol includes context symbols and a corresponding input symbol, and summing over values for the context symbols corresponding to the particular input symbol. An error correction decoder performs error correction decoding using the generated reliability information.
