As the signal-to-noise ratio and the noise structure are unknown, a Gaussian setup is incorrectly assumed. We derive the exact analytic expression for the error of the mismatched Bayes estimator and also provide the analysis of an approximate message passing (AMP) algorithm. The first result exploits the asymptotic behavior of spherical integrals for rectangular matrices and of low-rank matrix perturbations; the second one relies on the design and analysis of an auxiliary AMP. The numerical experiments show that there is a performance gap between the AMP and Bayes estimators, which is due to the incorrect estimation of the signal norm."}],"publication_status":"inpress","month":"06","date_created":"2024-02-02T11:20:39Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2302.03306"}],"author":[{"full_name":"Fu, Teng","last_name":"Fu","first_name":"Teng"},{"full_name":"Liu, YuHao","last_name":"Liu","first_name":"YuHao"},{"full_name":"Barbier, Jean","last_name":"Barbier","first_name":"Jean"},{"id":"27EB676C-8706-11E9-9510-7717E6697425","full_name":"Mondelli, Marco","last_name":"Mondelli","orcid":"0000-0002-3242-7020","first_name":"Marco"},{"first_name":"ShanSuo","last_name":"Liang","full_name":"Liang, ShanSuo"},{"last_name":"Hou","first_name":"TianQi","full_name":"Hou, TianQi"}],"language":[{"iso":"eng"}],"publication":"Proceedings of 2023 IEEE International Symposium on Information Theory","day":"30"}
