Abstract: In an inference verification method for verifying a trained first machine learning algorithm, a set of data samples are input to each of a plurality of at least three different trained machine learning algorithms and a set of outcomes are obtained from each algorithm. The plurality of trained machine learning algorithms are the same as the algorithm to be verified except that each of the plurality has been trained using training data samples where at least some of the outcomes are different as compared to training data samples used to train the first algorithm. For each sample in the data set input to the plurality, the method further comprises determining whether all of the outcomes from the plurality are the same. When all of the outcomes from the plurality are the same, the first algorithm is reported as being potentially defective for that sample in the input data set.

Abstract: A computer-implemented method of reconciling values of a feature, each value being provided by a different artificial intelligence (AI) system, by collecting logs from the different AI systems, each log including a value of the feature; identifying any discrepancy between the values. When there is any discrepancy, creating global information from the values, the global information taking into account some or all of the values. When the global information differs from the value of one of the AI systems, sending the global information to that AI system.

Abstract: A controller (12) is used for privacy management in an identity network (10) for a principal (20). An identity network (10) is a computer network including at least an identity provider (14), a discovery service provider (16), and a service provider (18) with which the principal (20) can make transactions. A principal (20) is a system entity whose identity can be authenticated. An identity resource (14) is either data related to an identity or group of identities, or a service associated with an identity or group of identities. The controller (12) queries a discovery service provider to obtain information regarding available identity resources (14), it receives back addressing information for addressing attributes of the identity resources (14), and it then interacts, based on the addressing information, with a service provider (18) to create, read, modify or delete a privacy attribute governing the use of an identity resource (14).

Abstract: A method is carried out by a controller (100), a social network (200), a provider (300) and a terminal (400) of a primary user (450). After a trust relationship is set up (s10) between the controller (300) and social network (200), the terminal (400) accesses (s20) the provider (300). The provider (300) transmits (s30) to the terminal (400) a proposal to provide information relating to the provider (300) to secondary users of the primary user in the social network (200). If the terminal (400) accepts (s40) the proposal, the provider (300) transmits (s30) to the controller (100) a message including the information relating to the provider (300). The controller (300) obtains identification of the primary user (450) to whom the message relates and triggers (s70) transmission, to the secondary users, of the information relating to the provider (300). A controller (100), a system (500) and computer programs are also disclosed.
