Model Based Prior

Model-based priors leverage pre-existing knowledge or learned representations to improve the efficiency and performance of machine learning models, particularly in data-scarce scenarios. Current research focuses on incorporating diverse priors, including those derived from large language models, 3D diffusion models, and other pre-trained networks, into various architectures such as GANs, diffusion models, and Bayesian optimization frameworks. This approach enhances model robustness, reduces the need for extensive training data, and improves the quality of generated outputs across diverse applications, including image synthesis, 3D reconstruction, and robot motion planning. The resulting improvements in sample efficiency and model accuracy have significant implications for various fields, from computer vision and robotics to reinforcement learning.
