摘要： The present disclosure relates to a Network Element (NE) and a management entity for supporting Anomaly Detection (AD) in a communication network. The NE is configured to determine, based on a local AD model, a point to be an anomalous point in Key Performance Indicator (KPI) time-series data, provide the anomalous point to the management entity, receive a label for the points of the KPI time series data from the management entity, and update the local AD model based on the received label. The management entity is configured to receive, from the NE, a point determined to be an anomalous point, and provide to the NEs, a label for the point. The management entity is further configured to receive, from the NE, a parameter of an updated local AD model of that NE, and update a global AD model based on the received parameter.

摘要： For a communication network using a satellite-involved backhaul, the backhaul outage and restoration states are predicted based on satellite motion data. Based on such predictions, devices providing the core portion of the communication network, and nearby Internet or backhaul radio devices can schedule or take actions. Actions can include but are not necessarily limited to: powering equipment up or down, suspending communications, migrating software from servers being powered down, transmitting replies to packets to indicate an anticipated outage and optionally anticipated outage end time, marking packets with congestion indications, closing or reopening certain ports, withdrawing or reinstating routing table addresses, and transmitting outage notifications to users or devices.

摘要： The present disclosure relates to methods and devices for performing neural network pruning in the field of machine learning. In particular, each layer of a trained neural network that comprises a first set of discrete weights is represented by a continuous parameter representation. The continuous parameter representation is based on a linear combination of Riemann integrable functions. Then, said continuous parameter representation may be discretized to obtain a second set of discrete weights of a desired size for that layer. In this way, neural network pruning is performed and the size of the neural network may be changed at the inference phase. Moreover, there is no need to fine-tune the second set of discrete weights because of the continuous parameter representation.

It is provided a method of encoding at least a portion of an image, comprising encoding a primary component of the image independently from at least one secondary component and encoding the at least one secondary component of the image using information from the primary component. Further, it is provided a method of encoding at least a portion of an image, comprising providing a residual comprising a primary residual component for a primary component of the image and at least one secondary residual component for at least one secondary component of the image that is different from the primary component, encoding the primary residual component independently from the at least one secondary residual component and encoding the at least one secondary residual component using information from the primary residual component.

摘要： The present disclosure provides an image processing apparatus for mitigating the effects of image degradation, the image processing apparatus comprising one or more processors configured to: receive two or more images depicting at least a portion of a common subject; calculate at least one optical offset between the two or more images;extract, from each of the two or more images, one or more feature representations, each of which represents tensor data based on the two or more images; extract, from the one or more feature representations, a plurality of patches, which represent one or more characteristics of the two or more images; generate, for each of the plurality of patches, a warp corrected patch by applying a warping operation, the warping operation being based on the calculated at least one optical offset between the two or more images; generate, for each of the plurality of patches, a plurality of kernels based on each warp corrected patch; correct, for each of the warp corrected patches, distortions of the characteristics of the two or more images based on the plurality of kernels; generate, for each of the warp corrected patches, a convolved patch by applying a convolution; and combine each of the convolved patches into an output feature representation. This provides the ability to account for motion in the scene when combining images, adaptively process and aggregate corresponding regions in different image frames and maximize restoration quality at the end of the image processing pipeline.

摘要： A method to select a number of fibers for ROADM-equipped nodes of an optical network by which a controller is operative to determine which links are utilized as well as their usage frequencies and then partition a scale of usage frequencies into a number of intervals. By assigning a number of fibers to each one of the intervals, a number of fibers is assigned to each link, according to their usage frequencies, setting the degree for ROADMs at the nodes. Simulations can evaluate the network's performance in terms of a blocking rate representing an overall signal blocking rate by the ROADMs at network nodes. The number of intervals, their ranges, and the number of fibers associated with each interval can be iterated until an improved or satisfactory network performance is achieved.
