Evaluate model (no experts) on LAI downstream task

• Select ROIs with common dates between S1 and S2
• Train MLPs (same architecture as in #3 (closed))
  • Using S2 latent (mean and logvar)
  • Using S1 latent (mean and logvar)
  • Using the sum of both latents: Z \sim N(\mu_X + \mu_Y, \sigma_X^2 + \sigma_Y^2)
