Membership inference
Membership inference is a privacy attack on machine learning models that determines whether a given record was in the training data, first demonstrated by Reza Shokri and colleagues in 2016.
Membership inference attack
A membership inference attack (MIA) determines whether a data record was part of a machine learning model's training dataset, revealing sensitive information such as health conditions.
Membrane bioreactor
A membrane bioreactor, also called a membrane biological reactor, is a wastewater treatment process that combines activated sludge with membrane filtration, replacing the secondary clarifier.
Membrane contactor
A membrane contactor is a separation device that transfers gas or liquid between two fluids across a microporous membrane, used for carbon dioxide capture and water degassing.
Membrane distillation
Membrane distillation is a thermally driven desalination process in which water vapor passes through a hydrophobic microporous membrane; it runs at ambient pressure on low-temperature heat such as waste heat or solar energy.
Membrane electrode assembly
A membrane electrode assembly (MEA) is the layered core of a PEM fuel cell or water electrolyzer, where the electrochemical reactions occur and which largely determines efficiency, lifetime, and cost.
