Adjoint sensitivity analysis on chaotic dynamical systems by Non-Intrusive Least Squares Adjoint Shadowing (NILSAS)

Angxiu Ni, Chaitanya Talnikar

We develop the NILSAS algorithm, which performs adjoint sensitivity analysis of chaotic systems via computing the adjoint shadowing direction. NILSAS constrains its minimization to…

Least Squares Shadowing method for sensitivity analysis of differential equations

Mario Chater, Angxiu Ni, Patrick J. Blonigan +1

For a parameterized hyperbolic system $\frac{d u}{d t} = f (u, s)$ the derivative of the ergodic average $⟨ J ⟩ = lim_{T \to \infty} \frac{1}{T} \int_{0}^{T} J (u (t), s)$ to the par…
