  • Publication number: 20240070238
    Abstract: The present disclosure relates to systems and methods for embedding concealed meta-data into DNNs. Specifically, the system and method presented consists of receiving a trained neural network that includes one or more layers each having weights. The disclosed process includes transforming at least one layer to a transformed domain, adding information to the layer(s) in the transformed domain, and performing an inverse domain transform on at least one layer such that the layer(s) has new weights with an embedded watermark.

  • Patent number: 11777598
    Abstract: Systems and methods are provided for utilizing polarization parameters obtained from an optical network to determine vibrations in optical fibers using coherent optics equipment and machine learning techniques. A method, according to one implementation, includes the step of obtaining a time-series dataset that includes measurements of polarization characteristics of light traversing an optical fiber of an optical network. The method also includes the step of detecting vibration characteristics of the optical fiber based on the time-series dataset. In some implementations, the time-series dataset may be a multi-variate dataset and the polarization characteristics may be related to transients in a State of Polarization (SOP). The SOP, for example, may be represented by an amplitude and a phase of an electric field vector and may be defined as having one of a linear polarization, elliptical polarization, and circular polarization.

  • Patent number: 11451332
    Abstract: A method, device and system for correcting errors in a group of received packets having a redundant packet. The method includes determining an inconsistent bit indicator for a bit position of the packets, determining a bit reliability indicator indicative of a potential bit error location in at least one packet, calculating a number of potential bit error locations for the bit position and identifying a correctable bit location accordingly. A method, device and system for correcting an error in a received packet. The method is adapted to calculate a checksum value of the received packet, verify if the checksum value is indicative of at least one bit error in the received packet, identify a predefined Checksum Pattern Type (CPT) according to the checksum value and determine at least one bit error event (BEE) accordingly. A method, device and system for decoding a plurality of received fountain encoded symbols.

  • Patent number: 11356174
    Abstract: Systems, methods, and computer-executable programs are provided for estimating margin in a network path. A method, according to one implementation, includes the step of executing a section-based analysis by estimating a margin parameter for each section of a plurality of sections forming a path through a network. The margin parameter is related to at least an available Optical Signal-to-Noise Ratio (OSNR) parameter and a Required OSNR (ROSNR) parameter. The method further includes the step of combining the estimated margin parameters for the plurality of sections to obtain a section-based estimate. In response to determining that the section-based estimate falls outside an acceptable confidence range, the method includes executing an additional path-based analysis to modify the estimate of the margin parameter.
