摘要： 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.
摘要翻译：在线广告系统接收来自广告客户的广告，这也可能会为广告提供相关的预算，时间段约束，展示目标和效果权重。当广告从客户端从广告系统请求时，可以根据与广告相关联的预算和/或与广告相关联的展示次数目标来确定每个广告的出价。可以预测与广告请求相关联的广告效果，并且可以基于与广告请求相关联的性能权重和预测的表现来为每个广告确定出价。广告的出价可能会按广告的预算消耗速度或广告进展到广告展示目标的速度加权。根据广告的确定出价，从一个或多个广告中选择一个广告来显示给客户。

摘要： 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.

摘要： 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.
摘要翻译：在社交网络系统中，用户可以对对象执行不同类型的动作（例如，对于歌曲，用户可以购买，收听，推荐或喜欢歌曲）。社交网络系统上的对象可以包括对象属性（例如，对于歌曲，艺术家，类型和专辑是歌曲的对象属性）。可以以不同的方式聚合对一种对象执行的每种类型的动作。用户可以通过社交网络系统，社交网络系统上安装的第三方应用程序和社交网络系统外部的系统对对象执行操作。广告商可以基于针对特定对象的动作的多种不同动作类型和聚合来指定定向条件。用户可以根据与具有共同元素的对象的交互进行分类。然后可以将广告定位到分类用户。

摘要： An information handling system (IHS) may include a processor with multiple compute elements that decode pictures from an encoded video bitstream. Each compute element may perform a different part or sequential stage of a picture decoding process to obtain decoded pictures. A memory includes a decoded picture buffer that associates with a first stage of the sequential stages. The memory may also include respective decoded picture buffer snapshots for sequential stages other than the first sequential stage. A last sequential stage provides fully decoded pictures to a decoded picture pool in memory. The decoded picture buffer and decoded picture buffer snapshots may store pointers to decoded pictures in the decoded picture pool that the sequential stages need to perform decoding of pictures. In this manner, the sequential stages may share decoded pictures that the decoded picture pool stores.

摘要： A social networking system presents content items to users, who then provide feedback regarding pairs of content items. The feedback includes a selection of a content item of the pair of content items that was preferred by the user over the other content item. The social networking system uses this information to train a predictive model that scores content items based on quality. The content items may be advertisements. The social networking system uses the pair-wise comparisons of the advertisements to determine feedback coefficients in an advertising quality score prediction model using regression analysis of the pair-wise comparisons for each predictive factor in the model. In this way, the pair-wise comparisons are used to train the prediction model to understand which advertisements are more enjoyable than others. A feedback coefficient for each predictive factor may be computed based on the preferences received from the group of users.

摘要： A scalable layered video coding scheme that encodes video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video, adds error resilience to the enhancement layer. Unique resynchronization marks are inserted into the enhancement layer bitstream in headers associated with each video packet, headers associated with each bit plane, and headers associated with each video-of-plane (VOP) segment. Following transmission of the enhancement layer bitstream, the decoder tries to detect errors in the packets. Upon detection, the decoder seeks forward in the bitstream for the next known resynchronization mark. Once this mark is found, the decoder is able to begin decoding the next video packet. With the addition of many resynchronization marks within each frame, the decoder can recover very quickly and with minimal data loss in the event of a packet loss or channel error in the received enhancement layer bitstream. The video coding scheme also facilitates redundant encoding of header information from the higher-level VOP header down into lower level bit plane headers and video packet headers. Header extension codes are added to the bit plane and video packet headers to identify whether the redundant data is included.

摘要： An information handling system includes a processor that may perform preprocessing on a variable-length code (VLC) bitstream before decoding the bitstream. The bitstream includes multiple codewords. The processor analyzes incoming VLC bitstream information and generates codeword table information for storage in a system memory or a VLC codeword tables location. The processor generates a VLC lookup table from the information in the VLC codeword tables and stores that VLC lookup table in a system memory of the IHS. The VLC lookup table may exhibit two dimensional indexing by leading zero count and bit-length possibility.
