Abstract: A computer-implemented method including: receiving a first data set including a plurality of values for a plurality of features; identifying at least a first feature of the first data set that is non-redundant and at least a second feature of the first data set that is redundant; identifying one or more clusters of features in the plurality of features of the first data set, a first cluster of the one or more clusters including at least the first feature and the second feature; and controlling a display to display the first feature and one or more redundant features from the first cluster, the displayed one or more redundant features from the first cluster including the second feature.

Abstract: A computer-implemented method including: receiving a first data set including a plurality of values for a plurality of features; removing one or more features and associated values from the first data set to generate a second data set; determining feature importance of at least a subset of the features of the second data set using multiple-evaluation criteria; and performing an action using at least one feature of the second data set and the determined feature importance.

Abstract: A method for controlling a power beam process includes carrying out a plurality of test power beam processes using a power beam on one or more test components and determining a plurality of power distributions corresponding to the plurality of test power beam processes. The method includes determining a plurality of beam parameters, generating derived features based on the plurality of beam parameters, and determining a plurality of process characteristics of each test power beam process. The method further includes generating a comprehensive dataset, dividing the comprehensive dataset into a test dataset and a training dataset, and determining a plurality of key discriminative features from the plurality of derived features of a set of training power distributions of the training dataset.
