diffrax
diffrax is an ordinary differential equation solver library in the JAX ecosystem. It provides a variety of implicit and explicit solvers and supports efficient gradient computation through the adjoint method.
Timeline (last 90 days)
KPPax calls the diffrax library's implicit solvers and forward and reverse mode adjoints to integrate stiff chemical systems.
KPPax leverages diffrax's built-in adjoint integration to obtain exact gradients without manually deriving and writing adjoint equation code, avoiding the memory explosion and numerical instability that occur when automatic differentiation passes directly through stiff solvers.
Frameworks such as torchdiffeq and diffrax have built-in stiff solver options, such as Kvaerno5 in diffrax and dopri5 in torchdiffeq.
