jaxrts.experimental.SiiNN.NNModelExpandedZ.din

property NNModelExpandedZ.din: int

Effective input dimensionality of the original model.

Because the expanded representation replaces each ionization variable with two derived features, the internal dimensionality of the first layer is larger than the logical input dimension. This property returns the original input size expected by the user-facing interface.

Returns:

int – Number of logical input features before ionization expansion.
