![(A) A view of the [ t − 1 , t + 1 ] layers of a deep feed forward neural network h V , E , σ , w . The input layer (left) is parsed against a “hidden” layer (middle) trained on annotated datasets, which corresponds to the correct output node depending on the weights obtained for each node.

In contrast to the traditional feed‐forward neural network, the weightings are checked against the preset test matrix of possible contributing signals. The weights given to each entry of this solution space are then used to generate the corresponding output node. This architecture is theoretically generalizable to any single‐ or multitensor representation of the diffusion MR signal.](https://pub-med-central-images-cdn.bioz.com/pub_med_central_ids_ending_with_2189/pmc12862189/pmc12862189__HBM-47-e70460-g004.jpg)
