where 𝜆 is a hyperparameter set to a large number (100) so that 𝐾 11 is set close to 1 so as to eliminate degeneracies. The absolute value of the elements in 𝐾 calculated through this process would not be the actual rate constants of the propagating reaction in general. However, one can nonetheless calculate 𝑟 𝑖𝑗 by taking the ratio of 𝑘 𝑖𝑖 and 𝑘 𝑖𝑗 . Detailed information on the theory of setting up the system of ODEs, mathematical formulation, the code used to optimize the loss function, usage of fitted 𝐾 and 𝑓 to assess 𝐹 predictions can be found in the Supporting Information and GitHub repositories.
