摘要： Aspects of the present disclosure relate generally to indoor localization, for example, where GPS or other localization signals are unavailable. More specifically, aspects relate to using inertial navigation systems (132) such as accelerometers (136) and gyroscopes (134) to aid in the determination of the location of a user. Certain devices such as MEMS gyroscopes found in handheld client devices (104) should be calibrated to ensure accurate location information is obtained. In one aspect, a Vibration Energy Model process (FIG. 4B) is performed on shaking energy generated as a user walks with a mobile device to detect the direction the user is walking in. This information may be used as part of a signal fusion system to perform accurate indoor localization of the user, such as to provide enhanced maps and location services to the user.

摘要： A content-based image retrieval (CBIR) system has a front-end that includes a pipeline of one or more dynamically-constructed filters for measuring perceptual similarities between a query image and one or more candidate images retrieved from a back-end comprised of a knowledge base accessed by an inference engine. The images include at least one color set having a set of properties including a number of pixels each having at least one color, a culture color associated with the color set, a mean and variance of the color set, a moment invariant, and a centroid. The filters analyze and compare the set of properties of the query image to the set of properties of the candidate images. Various filters are used, including: a Color Mask filter that identifies identical culture colors in the images, a Color Histogram filter that identifies a distribution of colors in the images, a Color Average filter that performs a similarity comparison on the average of the color sets of the images, a Color Variance filter that performs a similarity comparison on the variances of the color sets of the images, a Spread filter that identifies a spatial concentration of a color in the images, an Elongation filter that identifies a shape of a color in the images, and a Spatial Relationship filter that identifies a spatial relationship between the color sets in the images.

摘要： During the processing of a transaction or other distributed computation, a computation management system creates a number of agents to handle various aspects or portions of the computations to be performed. Each agent progresses through a predefined set of state transitions which define the status of the agent at any point in time. The computation management system defines for each agent a set of dependencies, each dependency corresponding to a state transition which will be blocked until a particular state transition occurs in another specified agent. By defining selected combinations of dependencies for each agent, a variety of different interdependencies and cooperating protocols can be implemented. The distributed processing management system can be used both for managing transaction processing and for synchronizing events in other types of distributed computations.
摘要翻译：在处理交易或其他分布式计算期间，计算管理系统创建多个代理来处理要执行的计算的各个方面或部分。每个代理通过预定义的一组状态转换来进行，这些状态转换定义了任何时间点上代理的状态。计算管理系统为每个代理定义一组依赖关系，每个依赖关系对应于将被阻止的状态转换，直到在另一指定代理中发生特定状态转换。通过定义每个代理的依赖性的所选组合，可以实现各种不同的相互依赖性和协作协议。分布式处理管理系统可以用于管理事务处理和用于同步其他类型的分布式计算中的事件。

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for enhanced parallel latent Dirichlet allocation (PLDA+). A PLDA+ system is a system of multiple processors that are configured to generate topics from multiple documents. The multiple processors are designated as two types: document processors and matrix processors. The documents are distributed among the document processors. Generated topics are distributed among the matrix processors. Tasks performed on the document processors and matrix processors are segregated into two types of tasks: computation-bound tasks and communication-bound tasks. Computation-bound tasks are CPU intensive tasks; communication-bound tasks are network intensive tasks. Data placement and pipeline strategies are employed such that the computation-bound tasks and the communication-bound tasks are distributed to the processors in a balanced manner, and performed in parallel.

摘要： In one implementation, a computer-implemented method includes receiving at a server a request from an advertiser to target an ad to users of a computer-implemented social network, the request comprising data representing characteristics of the users that the advertiser desires to target. The method further includes ranking the users based on how similar the users' characteristics are to the received characteristics and an influence score for each user that indicates how influential the user is within the social network. The method also includes scoring the advertiser's request based on a bid from the advertiser for an opportunity to display the ad to one or more of the users and assigning the opportunity to display the ad to the one or more users based on a correlation between a score of the advertiser's request and one or more rankings of the one or more users.

摘要： In one implementation, a computer-implemented method includes receiving at a server information indicating activity levels of users of a computer-implemented social network or acquaintance relationships of the users on the computer-implemented social network. The method further includes generating by the server influence scores for the users based on the received information. The method also includes recursively propagating by the server an ad through the computer-implemented social network between users having an acquaintance relationship by transmitting the ad from a propagating user to a recipient user when a difference between a first influence score of the propagating user and a second influence score of the recipient user is greater than a threshold.
