    摘要： A process includes processing first and third data based on a bias of the first and third data with reference to an attribute, respectively, updating a first machine-learning-model based on second data obtained by the processing of the first data, and generating a second machine-learning-model by the updating of the first machine-learning-model, obtaining prediction-results by inputting, to the second machine-learning-model, fourth data obtained by the processing of the third data, determining ground-truths of the fourth data by clustering features of the fourth data, determining accuracy of the second machine-learning-model based on the prediction-results and the ground-truths, identifying, based on a difference between the first and second data, the attribute processed with a processing-amount larger than a predetermined-threshold, identifying a contribution-magnitude of the attribute to an inference-result of the second machine-learning-model, and determining, based on the contribution-magnitude, an influence-degree when the second machine-learning-model is trained by the second data.

    摘要： A semiconductor device includes a plurality of built-in memories, and each of the built-in memories includes a plurality of memory cells. Each built-in memory includes a selector circuit that connects a selected memory cell among the memory cells to an outside, a memory cell relief circuit that, when a fault has occurred in one of the memory cells, transmits, to the selector circuit, a relief signal configured to connect a normal memory cell to the outside without connecting the one of the memory cells in which the fault has occurred, to the outside, and switches selection in the selector circuit, and an abnormality detection circuit that performs abnormality detection for the memory cell relief circuit, based on a temporal change in the relief signal output from the memory cell relief circuit.

    摘要： A method of implementing a revocable threshold hierarchical identity-based signature scheme may include receiving an identifier associated with a user. A first secret key based on the identifier may be generated. A string and the identifier may be directed to be posted on a block of a blockchain. A second secret key may be generated using the string, the first secret key, and the identifier. The block that includes the string and the identifier may be signed using the second secret key. A message may be signed using the second secret key to generate a signature. The signature may be provided to a device. The signature may be verifiable by the device using the string and the identifier obtained from the block by the device.
