Abstract: Neural network based systems, methods, and instrumentalities may be used to remove motion artifacts from magnetic resonance (MR) images. Such a neural network based system may be trained to perform the motion artifact removal tasks without reference (e.g., without using paired motion-contaminated and motion-free MR images). Various training techniques are described herein including one that feeds the neural network with pairs of MR images with different levels of motion contamination and forces the neural network learn to correct the motion contamination by transforming a first image of a contaminated pair into a second image of the contaminated pair. Other neural network training techniques are also described with an aim to reduce the reliance on training data that is difficult to obtain.

Abstract: A system derives training set factors for a customer sentiment score associated with a training set customer corresponding to training set support tickets, and a training set factor for a rate of a critical status corresponding to the training set support tickets. The system uses the training set factors to train a machine-learning model to determine a customer health score associated with the training set customer. The system derives factors for a customer sentiment score associated with a customer corresponding to support tickets, and a factor for a rate of a critical status corresponding to the support tickets. The trained machine-learning model uses the factors to determine a customer health score associated with the customer. The system enables a selection of escalating any customer account, de-escalating any customer account, escalating any support ticket, and/or de-escalating any support ticket, associated with the customer, in response to outputting the customer health score.
