Accurate Estimation of Mutual Information in High Dimensional Data
Researchers have developed a new protocol to improve the accuracy of mutual information estimation in high-dimensional data, a common challenge in modern scientific experiments. This method is particularly effective when the data's statistical dependencies can be represented in a lower-dimensional latent space. The protocol includes statistical consistency checks, bias correction, and confidence intervals, along with a new family of probabilistic critics to enhance performance in challenging scenarios. It has been validated on various synthetic and real-world datasets, including image data, demonstrating reliable estimation even when the ambient dimension is high. AI
