As mentioned in the introduction and in Section 3.2, we anticipate two kinds of region where the potential can be set to the LD potential. One is the region where two subsystems dissociate and another region is where two atoms get very close. To illustrate the use of a parametrically managed activation function, we next give an example suitable for treating the dissociation case. Section 3.1 converted the problem of achieving a physical extrapolation to asymptotic regions into the problem of how to satisfy eq (24). In regression problems, the output layer often employs the identity function as an output activation function as shown in eq (3). To satisfy eq (24), we generalize eq (3) to 𝒛 ,-* = (𝐰 ,-+ ) 0 𝐚 ) ,-+ + 𝐛 ,-+ (25)
