using logarithms and exponents in the differential equation

[Liza23]

Is a there a way to ensure that my differentials don't blow up? My differential equation has an exponent and log term which is making the values undefined/ too large and I'm getting the solutions as nan (which is because the differentials are blowing up to inf).

Hi Liza, can you be more specific as to what your equation is? If the log/exp are on your independent variables (e.g. t), I would recommend constraining your training domain, so that it doesn't sample points where things blow up.
