The method includes obtaining parameters defining physical properties of the electric motor, obtaining parameters defining drive currents for driving the electric motor, processing the obtained parameters using a machine learning module trained a priori to predict a spatially varying electromagnetic and/or mechanical and/or thermal profile within the electric motor during operation, and providing as output a predicted profile for the electric motor, and using the predicted profile to compute the one or more performance parameters of the electric drive unit.

Abstract: Embodiments maintain a data pool that includes heterogeneous data sets, and receiving a first data batch of a data set from a data source into the data pool. Embodiments determine a current state of the data set based on a data set state diagram including a plurality of data set states, and identify a condition of the first data batch. Embodiments further set a data batch state for the first data batch, based on a data batch state diagram, and update the data batch state of a prior data batch received before the first data batch, based on the condition of the first data batch. Embodiments additionally transition the data set state diagram, based on the condition of the first data batch, to an updated data set state. Embodiments maintain a data state repository storing the data set state for each of the plurality of heterogeneous data sets.

Abstract: In anomaly detection of a substance, a first set of chemical fingerprints is obtained. Each fingerprint in the first set is indicative of a plurality of physiochemical properties for a normal sample of the substance. The first set is converted into a cluster of data points in a multi-dimensional principal component analysis (PCA) plot. Each dimension of the plot is based on a principal component (PC) corresponding to one of the physiochemical properties. A profile pattern of the cluster of data points is constructed as a prediction model to identify a new sample with a chemical fingerprint outside the profile pattern as an anomaly. The prediction model is optimized using a second set of chemical fingerprints. Each chemical fingerprint in the second set is indicative of the plurality of physiochemical properties for testing samples that include normal testing samples and abnormal ones of the substance.
