Researchers have developed a new method called Bayesian Membership Inference Attack (BMIA) to more efficiently detect if specific data points were used in a model's training. This approach uses Bayesian sampling and Laplace approximation on a single reference model to estimate conditional score distributions, reducing the computational overhead compared to existing methods that require multiple reference models. Experiments show BMIA achieves state-of-the-art effectiveness and efficiency across various data types. AI
