Abstract: The systems and methods described herein optimize the retrieval of missed content by playing back cached content to enable tuners with limited capacity to retrieve the missed content. A content presentation system may receive, with a tuner, a transmission of content comprising media content and advertisements. The content presentation system may cache the advertisements. The content presentation system may determine whether an interruption during the transmission resulted in a missed portion of content and, in response, determine whether an advertisement upcoming at a time period in the transmission of content is cached. If the upcoming advertisement is cached, the content presentation system may play back the cached advertisement at the time period and release the tuner previously receiving the transmission of content to retrieve the missed portion of the content during the time period.

Abstract: In some aspects, the described systems and methods provide for validating performance of a model trained on a plurality of annotated pathology images. A pathology image is accessed. Frames are generated using the pathology image. Each frame in the set includes a distinct portion of the pathology image. Reference annotations are received from one or more users. The reference annotations describe at least one of a plurality of tissue or cellular characteristic categories for one or more frames in the set. Each frame in the set is processed using the trained model to generate model predictions. The model predictions describe at least one of the tissue or cellular characteristic categories for the processed frame. Performance of the trained model is validated based on determining a degree of association between the reference annotations and the model predictions for each frame and/or across all frames in the set of frames.

Abstract: Systems and methods are provided for determining a request to validate data, the request specifying validation criteria; generating a graph for validating the data, the graph including at least one node-based connected component that evaluates the data, the node-based connected component being constructed to represent the validation criteria; validating the data using the generated graph, wherein the data being validated is evaluated by the node-based connected component; and providing information describing the validated data.

Abstract: In a network environment, network health is monitored by a monitoring platform and related monitoring services. A method may include receiving metrics data from a plurality of data sources, overlaying a traffic profile for a client of the network with the metrics data to determine an experience score for the client, and detecting an impairment in the network based on the metrics data and/or the experience score. The method may further include performing a triangulation process to determine a cause of the impairment in the network based on the metrics data, and generating, for display via a user interface, a report indicating the impairment and the cause of the impairment.
