Conditional Density

Conditional density estimation focuses on learning the probability distribution of a variable given the values of other variables, aiming to accurately model complex relationships within data. Current research emphasizes developing flexible and efficient methods, employing diverse model architectures such as neural networks (including normalizing flows and energy-based models), tree-based methods, and kernel methods, often combined with techniques like knowledge distillation or contrastive learning to improve accuracy and efficiency. This field is crucial for various applications, including robust uncertainty quantification in machine learning, improved generative modeling, and accurate inference in complex systems across diverse scientific domains.
