Figure 19.

This figure visualizes the three different $\lambda$ update strategies. Orange boxes stand for the gradient with respect to the network parameters of the ODE loss ${\nabla }_{\overrightarrow{\theta }}{ℒ}_{ODE}$. Blue boxes stand for the gradient with respect to the network parameters of the data loss ${\nabla }_{\overrightarrow{\theta }}{ℒ}_{Data}$. Almost transparent blue boxes indicate that the respective data was not observed and is therefore not considered in the loss functions.
