摘要： An adaptive pattern classifier makes use of training patterns and a known non-linear invariance transformation to generate a classifier representation based on an infinite set of virtual training samples on a training trajectory. Given the non-linear invariance transformation, optimization can be formulated as a semidefinite program (SDP), which is given by a linear objective function that is minimized subject to a linear matrix inequality (LMI). In this manner, a small training set may be virtually supplemented using the non-linear invariance transformation to learn an effective classifier that satisfactorily recognizes patterns, even in the presence of known transformations that do not change the class of the pattern.

摘要： Matchmaking processes at online game services often result in players having to wait unacceptably long times to receive a match or immediately receiving a poorly matched session. By using a matchmaking process which dynamically adapts a good balance is achieved between the quality of proposed matches (for example, in terms of how balanced, interesting and fun those matches are likely to be) and the waiting time for potential matches. A matchmaking threshold is specified. When a player seeks a match a waiting time is observed, for example, as to how long that player waits until starting a game or dropping out. Information about such waiting times is used to dynamically update the matchmaking threshold. The update is made on the basis of a relationship between information about the observed waiting time and a target waiting time. Further control may be achieved by using separate matchmaking thresholds and target waiting times for different game categories.
摘要翻译：在线游戏服务中的对接过程通常会导致玩家不得不等待不可接受的长时间接收匹配或立即接收到不良匹配的会话。通过使用匹配过程，动态地适应所提出的匹配的质量之间的良好平衡（例如，在这些匹配的平衡，有趣和有趣的可能性方面）以及潜在匹配的等待时间。指定匹配阈值。当玩家寻找比赛时，观察到等待时间，例如，玩家在开始游戏或退出之前等待多久。关于这种等待时间的信息用于动态地更新配对阈值。更新是根据观察到的等待时间的信息与目标等待时间之间的关系进行的。可以通过对不同的游戏类别使用单独的配对阈值和目标等待时间来实现进一步的控制。

摘要： A publishing engine captures commercial information associated with a first user and automatically notifies other users in the first user's social network of this commercial information. The first user authorizes an e-commerce system to access his or her social network and to publish commercial information about the first user's commercial activity (e.g., a purchase or other commercial transaction) to users in the social network. By this automated notification, the notified users in the first user's social network can learn that the first user has completed a commercial transaction pertaining to a particular product or service. If a notified user is interested in a similar product or service, he or she can contact the first user to inquire about the first user's experience and information with the product or service.

摘要： A process for determining relative player skills and draw margins is described. Information about an outcome of a game between at least a first player opposing a second player is received. Also, for each player, skill statistics are received associated with a distribution representing belief about skill of that player. Draw margin statistics are received associated with a distribution representing belief about ability of that player to force a draw. An update process is performed to update the statistics on the basis of the received information about the game outcome. In an embodiment a Bayesian inference process is used during the update process which may take past and future player achievement into account.

摘要： There are many situations in which it is desired to predict outcomes of events. In an example, an event prediction system is described which receives variables for a proposed event. The system accesses learnt statistics describing belief about weights associated with the variables and uses the weights to determine probability information that the proposed event will have a specified outcome. The process involves combining the accessed statistics and mapping them into a number representing the probability. In another example, a machine learning process using assumed density filtering is used to learn the statistics from data about observed events. The event prediction system may be used as part of any suitable type of system such as an internet advertising system, an email filtering system, or a fraud detection system.

摘要： Based on the time series data from multiple components, the systems administrator or other managing entity may desire to find the temporal dependencies between the different time series data over time. For example, based on actions indicated in time series data from two or more servers in a server network, a dependency structure may be determined which indicates a parent/child or dependent relationship between the two or more servers. In some cases, it may also be beneficial to predict the state of a child component, and/or predict the average time to a state change or event of a child component based on the parent time series data. These determinations and predications may reflect the logical connections between actions of components. The relationships and/or predictions may be expressed graphically and/or in terms of a probability distribution.
摘要翻译：基于来自多个组件的时间序列数据，系统管理员或其他管理实体可能希望随着时间的推移找到不同时间序列数据之间的时间依赖性。例如，基于来自服务器网络中的两个或多个服务器的时间序列数据中指示的动作，可以确定依赖结构，其指示两个或多个服务器之间的父/子或依赖关系。在某些情况下，基于父时间序列数据预测子组件的状态和/或预测子组件的状态改变或事件的平均时间也可能是有益的。这些确定和预测可能反映组件的动作之间的逻辑连接。关系和/或预测可以以图形和/或以概率分布来表示。

摘要： Event prediction in dynamic environments is described. In an embodiment a prediction engine may use the learnt information to predict events in order to control a system such as for internet advertising, email filtering, fraud detection or other applications. In an example one or more variables exists for pre-specified features describing or associated with events and each variable is considered to have an associated weight and time stamp. For example, belief about each weight is represented using a probability distribution and a dynamics process is used to modify the probability distribution in a manner dependent on the time stamp for that weight. For example, the uncertainty about the associated variable's influence on prediction of future events is increased. Examples of different schedules for applying the dynamics process are given.

摘要： Reputation systems have been used to promote trust between participants in activities including online activities such as online market places. Existing online market places provide a reputation system which is a simple cumulative registry of user ratings on a given market place member. However, this simple system is open to abuse in situations where, for example, many positive ratings are given in a fraudulent manner. By modeling both reputation of participants and required reputation of participants an improved reputation system is provided. The required reputation may be thought of as a threshold, referred to herein as a required threshold, which may be used in determining how to update an indication of the reputation of a participant in the activity. The reputation system is able to learn information about required reputation and reputation of participants using an update process which is robust to participants who consistently give feedback of a particular type.

摘要： Online recommendations are tracked through a forwarding service. For example, a user may send an email to a friend recommending a product specified at a web site identified by a URI embedded in the email. Before sending the email, the user submits the URI to a forwarding service, which returns a new URI mapped to the original URI and to the recommending user. The recommending user can then recommend the web site by forwarding the new URI to the friend. If the friend selects the recommended URI to review the web site, the forwarding service records the decision to review the web site and directs the friend to the recommended web site. The forwarding service maintains a database of recommendations made by the recommending user, recommendation consumed by the friend, etc. Incentives can be provided to the recommending user and the friend to encourage recommendations.
摘要翻译：通过转发服务跟踪在线建议。例如，用户可以向建议在由电子邮件嵌入的URI标识的网站上指定的产品的朋友发送电子邮件。在发送电子邮件之前，用户将URI提交给转发服务，转发服务返回映射到原始URI的新URI和推荐用户。然后推荐的用户可以通过将新的URI转发给朋友来推荐该网站。如果朋友选择推荐的URI来查看网站，则转发服务记录审查网站的决定，并将朋友指向推荐的网站。转发服务维护由推荐用户提出的建议的数据库，朋友消费的推荐等。可以向推荐用户和朋友提供奖励以鼓励推荐。

摘要： Online recommendations are tracked through a forwarding service. The forwarding service can provide such statistics to an ad service, which can provide incentives to the recommending user and a consuming user. Example incentives may include an accumulation of points by the recommending user, a discount to the consuming user if a purchase is made in response to the recommendation, etc. To determine how much of an incentive each participant in the recommendation flow receives, a graph is created to model the recommendation flow and incentives are allocated using a cooperative game description based on this graph that associates each participant with a power index that represents that participants share of the incentive.
