Abstract: A system (e.g., an auto-encoder system) includes an encoder, a decoder and a learning module. The encoder generates compressed video data using a lossy compression algorithm, the lossy compression algorithm being implemented using a trained neural network with at least one convolution, generate at least one first parameter based on the compressed video data, and communicate the compressed video data and the model to at least one device configured to decode the compressed video data using an inverse algorithm based on the lossy compression algorithm. The decoder generates decoded video data based on the compressed video data using the inverse algorithm and the model, and generate at least one second parameter based on the decoded video data. The learning module trains the model using the at least one first parameter and the at least one second parameter.

Abstract: A system and method for data stream processing. Two or more instances are connected as a topology, wherein at least one of the instances is a spout and at least one of the instances is a bolt. The topology is submitted to a scheduler, wherein the service scheduler receives resource offers from a cluster manager representing computing resources available on one or more of cluster nodes and determines resources to accept and computations to run on the accepted computing resources. The topology is scheduled as one or more jobs, wherein each job includes two or more containers, including a first container and a second container, the first container including a topology master and the second container including a stream manager and one or more stream processing system (SPS) instances, wherein each SPS instance represents one of the instances in the topology.

Abstract: The present invention relates generally to messaging platforms, and relates more particularly to data storage such that random sampling can be accomplished in real-time in messaging platforms. Aspects of the present invention include storing a bipartite graph with associations of two node types. The graph can be stored as a power law graph. The graph can be used to provide real-time content recommendations in a messaging platform. The content recommendations can be provided using random sampling of the node types stored in the graph.

Abstract: A method of operating a messaging platform, including: obtaining, for a first profile of the messaging platform, a trending entity within a first topic of interest to the first profile; accessing a first plurality of messages classified as the first topic of interest; retrieving a subset of the first plurality of messages corresponding to the trending entity; and sending content associated with the subset for display to a user of the first profile.

Abstract: A real-time messaging platform allows advertiser accounts to pay to insert candidate messages into the message streams requested by account holders. To accommodate multiple advertisers, the messaging platform controls an auction process that determines which candidate messages are selected for inclusion in a requested account holder's message stream. Selection is based on a bid for the candidate message, the message stream that is requested, and a variety of other factors that vary depending upon the implementation. The process for selection of candidate messages generally includes the following steps, though any given step may be omitted or combined into another step in a different implementation: targeting, filtering, prediction, ranking, and selection.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for detecting sources of computer network failures. One of the methods includes identifying a network flow in a computer network between a source and a destination; performing a first probe to determine whether there is end-to-end connectivity between the source and the destination; in response to determining that there is no end-to-end connectivity between the host and the destination, performing one or more additional probes including a second probe to determine whether each hop in the path of the network flow between the source and the destination is operational including requesting that the source transmit a respective first trace diagnostic packet to each hop in the path of the network flow; and determining whether at least one link of the computer network that is part of the path of the network flow has failed based on the results.

Abstract: Systems and methods are described for load balancing between a set of servers. Subsets of servers from the set of servers are assigned, via deterministic subsetting, to respective clients from a set of clients. Unlike conventional load balancing techniques using deterministic subsetting, the disclosed techniques enable configuring a client to distribute different amounts of load among the servers in its server subset. Techniques for constructing the subsets are also described.
