Reconstruction of the interaction functions on simulated data. Reconstructions for (S-Haw) with $n=40$ trials, with $T_1=0.05$ and $T_2=2$. On the upper left, the interaction function $h_1^{(1)}$, on the upper right, $h_2^{(1)}$, on the bottom left$h_1^{(2)}$ and on the bottom right$h_2^{(2)}$. In black, the true interaction functions, in green, reconstruction by method ${\hat{f}}^{\mathrm{B}}$, in red, reconstruction by method ${\hat{f}}^{\mathrm{BO}}$. On the top of each graphics, the true spontaneous parameter ${\nu }^{(1)}$ on the top and the true parameter ${\nu }^{(2)}$ on the bottom are referred by <monospace>S</monospace>*. The estimated spontaneous parameters by method ${\hat{f}}^{\mathrm{B}}$ are referred as <monospace>SB</monospace> and the estimated spontaneous parameters by method ${\hat{f}}^{\mathrm{BO}}$ are referred as <monospace>SBO</monospace>. We used $K=8$, $\delta =0.005$, and $\gamma =1$
