    Abstract: One embodiment of the present invention sets forth a technique for compressing a forwarding table. The technique includes storing a first network prefix and a first set of routing information associated with the first network prefix in a routing table, and writing the first network prefix from the routing table to a first entry included in a forwarding table. The technique further includes storing a second network prefix and a second set of routing information associated with the second network prefix in the routing table. The second network prefix is covered by the first network prefix. The technique further includes, based on comparing the first set of routing information to the second set of routing information, determining that the second network prefix should not be written from the routing table to the forwarding table, or removing the second network prefix from the forwarding table.

    Abstract: One embodiment of the present invention sets forth a technique for correcting color values. The technique includes downsampling first color space values to generate downsampled color space values and upsampling the downsampled color space values to generate second color space values. The technique further includes modifying at least one component value included in the downsampled color space values based on a first component value included in the first color space values, a second component value included in the second color space values, and an approximation of a nonlinear transfer function.

    Abstract: Provided herein are systems and methods of managing permissions for applications deployed in a distributed computing infrastructure. An exemplary system includes an access management server having a processing device, a distributed computing infrastructure in communication with the management server having a plurality of resource instances and a request log, an administration system having a security application executing thereon. The security application has access policies associated with each of a plurality of applications. The processing device of the management server: receives application request information from the request log describing requests made by a first application being monitored by the access management server. The management server receives an access policy describing a set of accessible APIs associated with the first application from the security application and determines that access to a first API of the set should be removed, and modifies the access policy to remove access to the first API.

    Abstract: Provided herein are systems and methods of monitoring account activity in a streaming media environment. An exemplary system includes a monitoring system, an account creation and management system, and an account payment system. The monitoring system is coupled to the account creation and management system and the account payment system via a network. The processing device of the monitoring system retrieves account information for a first user account. Account information includes user consumption information and user payment information associated with the first user account. The processing device determines a fraudulent account score for the first user account based on at least one of the user consumption information, the user payment information, and account identification information. When the fraudulent account score exceeds an upper threshold, the processing device automatically deletes the first user account from at least one of the account creation and management system and the accounts payment system.

    Abstract: One embodiment of the present invention sets forth a technique for mitigating drift in audiovisual assets. The technique includes determining that an edit associated with a presentation timeline is within boundaries of a video frame. The technique further includes calculating a temporal drift associated with the edit, where the temporal drift comprises a duration of time between the edit and a boundary of the video frame. The technique further includes determining whether to include the video frame in the presentation timeline based on the temporal drift and an accumulated temporal drift associated with the presentation timeline.

    Abstract: Techniques are described for identifying a root cause of a pattern of performance data in a system including a plurality of services. Embodiments provide dependency information for each of the plurality of services, where at least one of the plurality of services is dependent upon a first one of the plurality of services. Each of the plurality of services is monitored to collect performance data for the respective service. Embodiments further analyze the performance data to identify a cluster of services that each follow a pattern of performance data. The first one of the services in the cluster of services is determined to be a root cause of the pattern of performance data, based on the determined dependency information for each of the plurality of services.

    Abstract: In one embodiment of the present invention, a training engine teaches a matrix factorization model to rank items for users based on implicit feedback data and a rank loss function. In operation, the training engine approximates a distribution of scores to corresponding ranks as an approximately Gaussian distribution. Based on this distribution, the training engine selects an activation function that smoothly maps between scores and ranks. To train the matrix factorization model, the training engine directly optimizes the rank loss function based on the activation function and implicit feedback data. By contrast, conventional training engines that optimize approximations of the rank loss function are typically less efficient and produce less accurate ranking models.
