The subject technology applies the selected differential privacy algorithm to the results to generate differentially private results. The subject technology provides the differentially private results.

Abstract: A local node for updating detection models while maintaining data privacy has an aggregation module, a retraining module, an instructions module, and a sharing module. The aggregation module aggregates the data into features that describe the contents of the data. The retraining module retrains the detection model using the features by implementing an algorithm that includes at least one selected feature and a threshold for triggering an activity alert. The instructions module determines instructions for calculating the at least one selected feature from a different collection of data. The sharing module generates a package having the instructions for calculating the at least one selected feature from the different collection of data and the threshold, and transmits the package to a local node for implementation of the retrained detection model with data stored at the local node.

Abstract: Systems and methods are described for modifying input and output (I/O) to an object storage service by implementing one or more owner-specified functions to I/O requests. A function can implement data access control, such as controlling which users are provided access to which portions of an object collection maintained by the object storage service. For example, data access control functions can be applied prior to implementing a request method (e.g., GET or PUT) specified within the I/O request, and may grant or deny access based on a variety of factors such as user identity, time window, prior access, keywords, geographical region, etc. In this manner, owners of the object collection are provided with greater control over how the object collection is accessed.

Abstract: Briefly stated, the invention is directed to retrieving a semantically matched knowledge structure. A question and answer pair is received, wherein the answer is received from a query of a search engine. A question is constraint-matched with the answer based on maximizing a plurality of constraints, wherein at least one of the plurality of the constraints is a similarity score between question and answer, wherein the constraint matching generates a matched sequence. For one or more answer sequences, a subsequence is found that are not parsed as answer slots. Query results are obtained from another search engine based on a combination of the answer or question, and the non-answer subsequence. And a KB based is refined on the query results and the constraint matching and based on a neural network training, for a further subsequent semantic matching, wherein the KB includes a dense semantic vector indication of concepts.

Abstract: The disclosure relates to decentralized management of nodes in a blockchain network. Participants may agree to a consensus rules and implement them as smart contracts. For example, one rule may specify that a node will accept a change proposal only when its local policies and/or data allow it to implement the change. A smart contract may implement this rule and deploy it across the blockchain network for each node to follow. Other participants, through their nodes, may propose changes to the blockchain network, and each node may consult its copy of the smart contract to determine whether to vote to approve the change request and apply the change request locally.
