WebApr 1, 2024 · The interpretation of these connections is not important once we accept that for some nodes in the first hidden layer the weights are different from zero, w j 1 (l) ≠ 0, and, therefore, carry information relevant for Granger causality and lag selection. For this reason, we shall not further pursue the identification of these parameters.
