摘要： Existing recommendation systems leverage user social and demographic information, e.g., age, gender and political affiliation, to personalize content and make recommendations. However, users do not volunteer this information due to privacy concerns or to the lack of initiative in filling out their profile information. The current methods and apparatus provide principles in which the system may learn the private attribute for those users who do not voluntarily disclose them. In an exemplary embodiment, the system receives ratings for items, such as movies, for example, that may be used by a recommendation system. The inventive arrangements are based on novel usage of Bayesian matrix factorization in an active learning setting. Such a system can be carried out using significantly fewer rated items than previously proposed static inference methods. The system functions effectively without sacrificing the quality of the regular recommendations made to the user.
摘要翻译：现有的推荐系统利用用户社交和人口统计信息（例如年龄，性别和政治隶属关系）来个性化内容并提出建议。但是，由于隐私问题或缺乏主动填写个人资料信息，用户不会自愿提供这些信息。当前的方法和装置提供了原理，其中系统可以为那些不愿意公开他们的用户学习私人属性。在示例性实施例中，系统接收例如可由推荐系统使用的项目（例如电影）的评级。本发明的配置基于在主动学习环境中的贝叶斯矩阵分解的新用法。这样的系统可以使用比先前提出的静态推断方法少得多的额定项目来执行。该系统可以有效运行，而不会影响向用户提供的常规建议的质量。

摘要： A method to obfuscate the accurate detection of demographic information of a new user who provides ratings to a digital content service having a recommender system includes training an inference engine to detect the 5 demographic information. The training set includes movie ratings and demographic information from a plurality of other users. The new user inputs ratings, such as movie ratings, and the inference engine determines the demographic information of the new user. An obfuscation engine then adds movie ratings to the recommender system which cause an inference engine in the recommender system to fail to accurately detect the demographic information of the new user.

摘要： A method is intended for computing an optimal family of K n-dimensional vectors of injection rates (I) of K contents for n users comprising communication equipments (CE1-CE3) coupled to a communication network (CN), with K = 1. This method comprises the steps of: i) determining the gradients of K objective functions (f(I)) each representative of n expectations of a non-increasing utility function (hi(Yi)) depending on a value representative of the age (Yi) of availability of one of the K contents into a user communication equipment (CEi), and ii) applying a gradient descent algorithm to these objective function gradients to determine the optimal family of K n-dimensional vectors of injection rates (I) of K contents.

摘要： A method, apparatus and system for microphone array calibration include recording audio using at least two microphones, which comprise an array of microphones, using a target microphone of the array of microphones, determining an attenuation factor for audio originating from respective locations of other microphones of the array of microphones, using a target microphone of the array of microphones, determining a delay factor for audio originating from respective locations of other microphones of the array of microphones and implementing the determined attenuation factor and delay factor for removing audio originating from respective locations of the other microphones of the array of microphones from an audio signal captured by the target microphone. The method, apparatus and system then further include removing audio originating from respective locations of the other microphones of the array of microphones from an audio signal captured by the target microphone using beam-forming techniques.

摘要： An apparatus and a method for designing a data market experiment given a fixed budget and a set of potential subjects for the experiment are described. An experimenter conducts an online survey, for example, or a test on human subject, or any other kind of experiment through which it collects data, and can incentivize the participation of subjects in the experiment through monetary compensation. The experimenter observes some publicly known information about the subjects, as well as the money each potential subject requests to participate in the experiment. Based on this information, the method determines which users to pay, and how much, to participate in the experiment. The method views experimental design in a strategic setting, by studying mechanism design issues, such as incentivizing users to report a truthful value for their data. The method has the following properties of being budget feasible, computationally tractable, nearly-optimal, and truthful in that the subjects have no incentive to declare desired compensations that are untruthful.
