We propose Generalized Forward-Inverse (GFI) framework based on two assumptions. First, according to the manifold assumption, we assume that the velocity maps v ∈ V and seismic
107
+
waveforms p ∈ P can be projected to their corresponding latent space representations, v˜ and p˜,
108
+
respectively, which can be mapped back to their reconstructions in the original space, vˆ and pˆ. Note
109
+
that the sizes of the latent spaces can be smaller or larger than the original spaces. Further, the size
110
+
of v˜ may not match with the size of p˜. Second, according to the latent space
111
+
translation assumption, we assume that the problem of learning forward and inverse mappings in
112
+
the original spaces of velocity and waveforms can be reformulated as learning translations in their
