摘要： According to an aspect, a method for ranking messages of conversation graphs in a messaging platform includes receiving a conversation view request to retrieve messages of a conversation graph stored on a messaging platform and determining a plurality of predictive outcomes for each of a plurality of messages of the conversation graph using predictive models. The determining step includes obtaining a plurality of signals relevant to the predictive models, the plurality of signals including data structure-related signals relating to the conversation graph and inputting the plurality of signals to the predictive models to determine the plurality of predictive outcomes. The method includes ranking, by the messaging platform, the plurality of messages based on the predictive outcomes, and transmitting, by the messaging platform over the network, at least a subset of the plurality of messages to be rendered on a client application according to the rank.

摘要： A computer system receives an account creation request for a social media platform created and sent using a frontend component. An application programming interface (API) call sequence associated with the account creation request is received from the frontend component. The API call sequence can reflect API calls registered by the frontend component in connection with creation of the account creation request, and timings of the registered API calls. An API call sequence model is applied to the API call sequence. The API call sequence model can be generated by providing training API call sequences to a machine learning component. At least one action is taken in response to the application of the API call sequence model indicating that the API call sequence is anomalous. The action can be taken with regard to the account creation request, or with regard to an account created in response to the account creation request.

摘要： Implementations provide a structure for low-latency live-video streams using existing content delivery networks. An example method includes creating, at the start of a broadcast stream, a playlist for the broadcast stream that identifies at least two segment files. The content of each of the segment files is a table header. The method also includes transmitting the playlist and each of the segment files to a cache server, obtaining the video broadcast stream as a series of frames, and transmitting each frame in the series of frames to the cache server using an HTTP chunk transfer protocol, each frame being associated with, and written to, a first segment file identified in the playlist. When a frame in the broadcast stream is a break frame, the method includes transmitting an end of file marker for the first segment file and adding a video header for the break frame before it is transmitted.

摘要： A method for distributed processing involves receiving a graph (G) of targets and of influencers, with each influencer related to at least one target, receiving an action graph of actions performed by one or more of the influencers, and key partitioning G across shards. The method further involves transposing the first graph (G) to obtain a first transposed graph (G T ), valuing partitioning G T across the shards, storing the action graph on multiple shards, issuing, to a shard, a request specifying an influencer, to perform an intersection, receiving a response to the request of a set of influencers each of which is related to a target, and determining whether to send a recommendation to the target based on the response.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for limiting load on host servers that implement a social messaging platform. An example user device sends, to a platform comprising a plurality of host servers, a first request. The request is directed to a first endpoint. The user device receives, in response to the first request, a first error that indicates that the first request was not processed. The user device determines a back off time and places subsequent requests to the platform that are initiated before the back off time elapses and that are directed to the first endpoint in a back off queue in an order in which the subsequent requests are initiated. The user device sends, to the platform, the requests in the back off queue after the back off time has elapsed, until the back off queue is empty.
