Abstract: An information handling system includes a multi-core processor that processes variable-length code (VLC) bitstream data. The bitstream data includes multiple codewords for interpretation. The processor includes a general purpose unit (GPU) and a special purpose unit (SPU). The GPU includes GPU buffers and the SPU includes SPU buffers. After populating one GPU buffer with bitstream data, the processor populates another GPU buffer with subsequent bitstream data. The processor may populate the GPU buffers in alternating fashion. The processor populates one SPU buffer with bitstream data while parsing bitstream data in the other SPU buffer. The GPU of the processor populates the SPU buffers in alternating fashion. The size of the GPU buffers may be a multiple of the size of the SPU buffers. After the SPU buffers consume the bitstream data from one GPU buffer, the other GPU buffer transfers its bitstream data to the SPU buffers for parsing.

Abstract: A story describing an activity performed by an interacting user is distributed to viewing users according to the influencer scores for the viewing users. Each influencer score can be calculated based at least in part on the influence of a viewing user on those users connected to the viewing user, and on the influencer scores for the users connected to the viewing user. Based on the determined influencer scores, at least one of the viewing users can be provided with the story describing the activity performed by the interacting user.

Abstract: Embodiments of the present disclosure target advertising to a group of related users of a social networking system. To target advertising to a group of users, the social networking system receives targeting criteria specifying a group to receive an advertisement at substantially the same time. To identify a group of users of the social networking system satisfying the targeting criteria, the social networking system observes the interactions of connected social networking system users. Connected users interacting with each other in a manner that satisfies the targeting criteria may be added to a group. The social networking system serves the advertisement to a set of users included in the group because the served users are members of the group.

Abstract: An ad publishing system provides ads of an advertiser's advertising campaign to a target group specified by initial targeting criteria. The publishing system evaluates results of advertising metrics for various segments of the target group based on user reactions to the initial presentation of the ads. Based on the advertising metric results for the various segments, the publishing system suggests to the advertiser a modification of the advertising campaign. Possible modifications to the advertising campaign include narrowing the initial targeting criteria to specify at least one of the segments as the target group, specifying a different ad for a low-performing segment, and adjusting the value of a bid for display of the ads in the campaign.

Abstract: An advertising system may enable an advertiser to associate multiple targeting criteria bids with an advertisement. The targeting criteria bids include a bid amount and a targeting criteria defining a group of users who may be delivered the advertisement. The cost for the advertisement is the sum of the bid amounts associated with the targeting criteria that match the user profile of the viewing user.

Abstract: The present invention provides a method of distributing content to a plurality of clients. The method on a server begins with accessing content to be distributed to a plurality of clients and identifying a first type of content to be distributed as crucial content and identifying a second type of content to be distributed as non-crucial content. The crucial content is any content required to properly render, after a decryption process, the content. The non-crucial content is all the other content to be distributed. The crucial content is encrypted with a first encrypting key which is unique to each of the plurality of clients. The crucial content which has been encrypted is transmitted. The non-crucial content is transmitted to the plurality of clients.

Abstract: An online advertising system receives ads from advertisers, which may also provide associated budgets, time period constraints, impressions goals, and performance weightings for the ads. When an ad is requesting from the advertising system from a client, a bid may be determined for each ad based on the budget associated the ad and/or the impressions goal associated with the ad. Ad performance associated with the ad request may be predicted, and a bid may be determined for each ad based on the performance weightings and the predicted performance associated with the ad request. The bid for an ad may be weighted by the pace of budget consumption by the ad, or by the pace of the ad progressing towards the ad's impression goal. An ad is selected for display to the client from among the one or more ads based on the determined bids for the ads.

Abstract: A social networking system may identify a first set of users as part of a training cluster and identify a second set of users that is similar to the first set of users for purposes of targeting advertisements related to the advertiser. Using past engagement history (e.g., click-through rates), demographic information, and keywords associated with the training cluster of users, a social networking system may generate a training model specific to the training cluster. Confidence scores may be used to identify similar users across the total population of users of the social networking system for creating a targeting cluster of users for the advertisement. A revenue sharing scheme may be used induce page administrators to increase their fan base by enabling advertisers to target advertisements to users that have expressed interest in pages associated with the page administrators.

Abstract: Techniques are disclosed for detecting new events in a video stream that yield improved detection efficiency in real time. For example, a method determines whether a given event is a new event in a video stream. The video stream includes a plurality of events. A first step extracts a first set of features (e.g., text features) from the given event. The first set of features is computationally less expensive to process as compared to a second set of features (e.g., image features) associated with the given event. A second step computes one or more first dissimilarity values between the given event and one or more previous events in the video stream using only the first set of features when one or more first dissimilarity criteria exist. A third step determines whether the given event is a new event based on the one or more computed first dissimilarity values.

Abstract: In a social networking system, users may perform different types of actions with respect to objects (e.g., for a song, a user can buy, listen to, recommend, or like the song). Objects on the social networking system may include object properties (e.g., for a song, an artist, genre, and album are the song's object properties). Each type of action performed on a type of object may be aggregated in a different way. Actions may be performed on objects by users through the social networking system, a third-party application installed on the social networking system, and systems external to the social networking system. An advertiser may specify targeting criteria based on multiple different action types and aggregations of an action with respect to a particular object. Users may be categorized based on their interactions with objects having a common element. Ads may then be targeted to the categorized users.

Abstract: Advertisements to be presented to a user are selected based on feedback responses received from other users where the feedback responses represent the level of interest to the advertisements expressed by the other users. In selecting which advertisements to be presented to a user, the online service takes into account feedback responses previously collected from a group of users and revenue expected for presenting certain advertisements to the user. An online service computing device computes a total value of an advertisement based on an estimated revenue value for presenting an advertisement and a modifier representing the user's estimated interest in the advertisements. The modifier is normalized based on a market value of the corresponding advertisement or a user. The online service then selects or prioritizes the advertisements based on the total values.
