Abstract: A computing device (e.g., a policy management server) obtains a segmentation policy that includes a set of rules for controlling network traffic between workloads. The computing device also receives infrastructure feedback regarding configuration of third-party network infrastructure. The computing device uses the infrastructure feedback to identify a discrepancy between the segmentation policy and the configuration of the third-party network infrastructure and triggers a corrective action in response. The corrective action may include providing a notification or suggestive remedy for the discrepancy to the user or automatically remedying the discrepancy.

Abstract: Systems and methods for detecting regions of interests (ROIs) in biomedical images are described herein. A computing system may identify a biomedical image having an ROI. The computer system may apply an object detection model to the biomedical image. The object detection model may generate a feature map using the biomedical image. The object detection model may generate an anchor box corresponding to a portion of the pixels in the feature map. The computing system may apply an instance segmentation model to identify a segment of the biomedical image within the anchor box corresponding to the ROI. The computer system may provide an output based on the segment to identify the ROI in the biomedical image.

Abstract: A method, referred to herein as upside down reinforcement learning (UDRL), includes: initializing a set of parameters for a computer-based learning model; providing a command input into the computer-based learning model as part of a trial, wherein the command input calls for producing a specified reward within a specified amount of time in an environment external to the computer-based learning model; producing an output with the computer-based learning model based on the command input; and utilizing the output to cause an action in the environment external to the computer-based learning model. Typically, during training, the command inputs (e.g., “get so much desired reward within so much time,” or more complex command inputs) are retrospectively adjusted to match what was really observed.

Abstract: Techniques for managing dataset resource instance performance via a data-centric approach are disclosed. A system determines an aggregated level of service demands placed on individual dataset resource instances that may be in a distributed computing system. The system may identify portions of a dataset that are associated with high levels of service demands. Once identified, the system may provide an administrator with the service demand information. The administrator may relocate these high demand dataset portions to other dataset resource instances that are better able to respond to the high levels of demand without impaired performance.

Abstract: A method for reporting a beam index by a wireless device including a controller, a beam predictor, and a radio transceiver. The method incudes obtaining an indication that the wireless device is to report a beam index to an access network node and obtaining the beam index from the beam predictor by providing information of current geographic position of the wireless device and current time as input to the beam predictor. The beam predictor is trained with tuples that associate at least different geographical positions and different points in time with different beam indices. The beam predictor predicts the beam index based on the current geographic position and the current time. The method includes wirelessly reporting, using the radio transceiver, the beam index as obtained from the beam predictor to the access network node.

Abstract: A growth predictor includes a monitor, a prediction engine, and a prioritization engine. The monitor receives or generates first information of a network already identified as a candidate money laundering (ML) network by an anti-money-laundering system. The prediction engine predicts second information indicative of a growth size of the ML network at a future time based on the first information. The prediction engine executes one or more predictive models to generate the second information indicative of growth size based on the first information, which indicates one or more changes that have occurred in the candidate ML network over a past period of time. The prioritization engine determines a priority of the candidate ML network based on the second information.
