On some composite Kies families: distributional properties and saturation in Hausdorff sense
Modern Stochastics: Theory and Applications, 2023 The stochastic literature contains several extensions of the exponential distribution which increase its applicability and flexibility. In the present article, some properties of a new power modified exponential family with an original Kies correction ...

Widely-Linear MMSE Estimation of Complex-Valued Graph Signals [PDF]
, 2022 In this paper, we consider the problem of recovering random graph signals with complex values. For general Bayesian estimation of complex-valued vectors, it is known that the widely-linear minimum mean-squared-error (WLMMSE) estimator can achieve a lower mean-squared-error (MSE) than that of the linear minimum MSE (LMMSE) estimator.

Multiobjective tree-structured parzen estimator for computationally expensive optimization problems
Annual Conference on Genetic and Evolutionary Computation, 2020 Practitioners often encounter computationally expensive multiobjective optimization problems to be solved in a variety of real-world applications. On the purpose of challenging these problems, we propose a new surrogate-based multiobjective optimization ...
