Abstract: A computerized machine learning anomaly detection model trained on a plurality of samples of one or more source domains (optionally, one or more source domains and the target domain) is accessed. Using online deep sets, one or more domain vectors are computed for each target domain sample at an observation point, each target domain sample corresponding to a given target domain, where the one or more domain vectors represent a similarity and difference among the source and target domains. The target domain sample is processed using the anomaly detection model trained on the plurality of samples of the source to generate an anomaly score, the processing being based on the computed one or more domain vectors.

Abstract: Embodiments of the invention describe a computer-implemented method of detecting anomalous data associated with a system-under-analysis. The computer-implemented method includes using a first encoder stage of a neural network to generate content-irrelevant latent code from input data. A second encoder stage of the neural network is used to generate domain-irrelevant latent code from the input data. A decoder stage of the neural network is used to generate reconstructed input data. The reconstructed input data includes a reconstruction of the input data based at least in part on the content-irrelevant latent code and the domain-irrelevant latent code. A reconstruction loss is generated based at least in part on the reconstructed input data. The reconstruction loss is used to determine that the input data includes an anomalous data candidate.

A neural network model is trained to identify a form of data augmentation that has been performed on a waveform using the normal data augmentation samples and the abnormal data augmentation samples.

Abstract: In order to improve the ductility or formability of a magnesium alloy, addition of rare earth elements or refinement of grain size is often used. However, conventional additional elements inhibit the action of grain boundary sliding for complementing plastic deformation. Therefore, it is required to search for additional elements that act to facilitate the grain boundary sliding not only at a conventional deformation speed but also in a higher speed range while maintaining a microstructure for activating non-basal dislocation. The present invention is to provide a wrought processed Mg-based alloy having excellent ductility at room temperature, which consists of 0.25 mass % or more to 9 mass % or less of Bi, and a balance of Mg and inevitable components, and is characterized by having an average grain size of an Mg parent phase after solution treatment and hot plastic working after casting of 20 ?m or less.
