摘要： An apparatus and method for establishing a trusted path between a user interface and a trusted executable, wherein the trusted path includes a hypervisor and a driver shim. The method includes measuring an identity of the hypervisor; comparing the measurement of the identity of the hypervisor with a policy for the hypervisor; measuring an identity of the driver shim; comparing the measurement of the identity of the driver shim with a policy for the driver shim; measuring an identity of the user interface; comparing the measurement of the identity of the user interface with a policy for the user interface; and providing a human-perceptible indication of whether the identity of the hypervisor, the identity of the driver shim, and the identity of the user interface correspond with the policy for the hypervisor, the policy for the driver shim, and the policy for the user interface, respectively.

摘要： A computer including a processor and a verification device. The processor in the computer performs the steps of authenticating a secure connection between a hypervisor and the verification device, measuring the identity of at least a portion of a select guest before the select guest executes any instruction, and sending a measurement of the identity of the select guest to the verification device. The verification device compares the policy stored in the verification device with the measurement of the select guest received by the verification device. The steps of authenticating, measuring, sending, and comparing are performed after receiving a signal indicative of a request to execute the select guest and without rebooting the computer.

摘要： A computer accesses an artificial intelligence (AI) model, a labeled in-sample (IS) dataset, and an unlabeled out-of-sample (OOS) dataset, the labeled IS dataset storing IS input values and corresponding IS output values, the unlabeled OOS dataset storing OOS input values but not corresponding OOS output values. The computer modifies, via importance sampling and based on a likelihood that a given datapoint from the IS dataset is associated with the OOS dataset, weights of multiple datapoints in the labeled IS dataset to generate a weighted IS dataset. The computer calculates an estimated performance metric of the AI model on the OOS dataset using at least a subset of datapoints in the weighted IS dataset. The computer provides an output representing the estimated performance metric of the AI model on the OOS dataset.

摘要： A new and useful updating tool is provided for indexing electronic text in a highly integrated electronic text indexing and search system. The integrated system encompasses a concept model, a query model, an enhanced markup tool, a user interface, and a search engine. A domain expert utilizes the integrated system to efficiently and effectively indexing electronic text for precise and fast retrieval by a search engine. The updating tool aids the indexing process as a consequence of changes in the query model, to an indexed document, or both. The updating tool comprises a document change tool and a query model change tool as well as an enhanced markup tool and an enhanced query model tool. The updating tool guides the domain expert by suggesting which indices need to be updated and flags index entries that need to be removed.

摘要： In some implementations, a computing machine accesses an artificial intelligence model and a dataset for the artificial intelligence model, the dataset comprising at least one datapoint. The computing machine identifies a feature group used by the artificial intelligence model, the feature group comprising at least two features having a similarity with one another exceeding a similarity threshold, wherein the feature group comprises a subset of the features used by the artificial intelligence model. The computing machine determines an overall influence value for the feature group on an output of the artificial intelligence model applied to the dataset. The computing machine provides an output representing the overall influence value.
