Efficient Latent Variable Model

Efficient latent variable models aim to learn underlying, unobserved factors (latent variables) that explain complex data patterns, improving model efficiency and interpretability. Current research emphasizes developing scalable inference methods, particularly using variational autoencoders and Gaussian processes, to handle high-dimensional data with structured missingness and heterogeneous sources. Applications span diverse fields, including healthcare monitoring, image reconstruction, and algorithmic fairness assessment, where these models offer improved accuracy and the ability to address challenges like limited labeled data or unknown forward models. The resulting advancements contribute to more robust and efficient machine learning across numerous domains.
