Researchers have introduced a novel approach to density estimation in high-dimensional spaces by leveraging pre-training, a technique common in advanced AI. This method utilizes a pre-trained neural network to suggest suitable location-adaptive kernels for each data point, thereby improving efficiency and accuracy. The effectiveness of this strategy is demonstrated in numerical experiments, particularly when the target distribution aligns with the pre-training distribution, with options for fine-tuning to adapt to different distributions.
