Averaging Method for Minimax Estimation of Functionals of Solutions to Parabolic Problems

abstract:
We study the problem of minimax estimation of functionals depending on the solutions of parabolic boundary value problems, where the observation model is based on time-averaging. Using the averaging method, we construct approximate minimax estimates and analyze the corresponding estimation errors. The obtained results show that the averaging approach provides effective tools for reducing the complexity of minimax estimation in parabolic systems with rapidly oscillating coefficients.
