Empirical MEM method achieves improved convergence rate

By PulseAugur Editorial · [1 sources] ·

Researchers have established a new parametric convergence rate of $O(n^{-1/2})$ in expectation for the empirical Maximum Entropy on the Mean (MEM) method, an improvement over the previous $O(n^{-1/4})$ guarantee. This advancement, detailed in a paper by Matthew King-Roskamp, is based on a novel stability analysis of optimization problems. The study also reformulates the MEM dual problem as an expected risk minimization problem, integrating it into stochastic optimization frameworks and enabling scalable algorithms for large-scale inverse problems.

    On the Computational and Statistical Efficiency of the Empirical Maximum Entropy on the Mean Method

    arXiv:2608.27705v1 Announce Type: cross Abstract: The Maximum Entropy on the Mean (MEM) method provides a flexible computational framework for solving inverse problems by combining data fidelity with entropy-based regularization. In practice, however, the prior distribution is ty…
