Abstract: Classifier accuracy is increased in machine learning applications by training a machine learning (ML) model including a classifier across classes by determining weighted input points for a contributing set to store the values for true positive and true negative predications. In a following step, input data is provided to the classifier of the machine learning model at runtime, and a classification output is determined from the classifier. For the classification output, values for input during runtime are compared with a sample of inputs stored for training the machine learning model to determine the distance in spread for the classification output. A class is determined from the classification output having a smallest distance and spread. The method can further determine if the class with the smallest distance and spread is a true positive or true negative by comparing the class with the smallest distance and spread with the classification output.

Abstract: Systems and methods for identifying visual features that influence a predictive model are provided. The technology employs an image translation function to introduce a visual feature into an image to create a modified image that can be fed to a predictive model. When the predictive model generates a different prediction for a given image than it does for a modified version of that image, the image translation function can then be used to make further modified versions that exaggerate the introduced visual feature. The technology thus aids in identifying visual features that influence the predictive model so that the model's conclusions can be understood, and so that those visual features can be further studied and tested.

Abstract: A processing plant for metal strips (1) has a welding machine, a strip store downstream of the welding machine and a processing device downstream of the strip store. The metal strips are welded to form a continuous strip with the welding machine, which is stored in the strip store and output from there to the processing device. The metal strips are connected via diagonally extending weld seams. To join the weld seams, first the strip head (2) and the strip foot (3) of the metal strips are twisted and the two strips are connected by forming the weld seam. The weld seam extends only transversely to the transport direction (x) during the welding process. Finally, the strip head and the strip foot of the metal strips are twisted back again. As a result, the weld seam now extends diagonally to the transport direction (x).
