    Abstract: A computer-implemented method for analyzing a time-varying graph is provided. The time-varying graph includes nodes representing elements in a network, edges representing transactions between elements, and data associated with the nodes and the edges. The computer-implemented method includes constructing, using a processor, adjacency and feature matrices describing each node and edge of each time-varying graph for stacking into an adjacency tensor and describing the data of each time-varying graph for stacking into a feature tensor, respectively. The adjacency and feature tensors are partitioned into adjacency and feature training tensors and into adjacency and feature validation tensors, respectively. An embedding model and a prediction model are created using the adjacency and feature training tensors. The embedding and prediction models are validated using the adjacency and feature validation tensors to identify an optimized embedding-prediction model pair.

    Abstract: A method of mapping transverse relaxation in a magnetic resonance (MR) scan data, comprises receiving a multi-echo spin-echo MR scan protocol comprising a plurality of MR imaging parameters, and for each echo of the multi-echo spin-echo MR scan protocol: generating, based on the parameters, a simulated echo modulation curve using a set of refocusing coherence pathways, for each of a plurality of predetermined transverse relaxation times; calculating, for each transverse relaxation time, diffusion attenuation based on a respective subset of the refocusing coherence pathways; and correcting the echo modulation curve using the diffusion attenuation. The method can also comprise comparing the scan data to the corrected echo modulation curve for each of at least a portion of the transverse relaxation values, and generating a displayed output comprising a map of transverse relaxation based on the comparison.
