Downsampling Method

Downsampling, the process of reducing the size of datasets while preserving essential information, is a crucial technique in various fields, primarily aiming to improve computational efficiency and reduce training costs for machine learning models. Current research focuses on developing more robust and efficient downsampling methods, including those that incorporate class-aware weighting, adaptive strategies based on content importance, and alias-free techniques to mitigate artifacts. These advancements are significantly impacting areas like image processing, natural language processing, and medical image analysis by enabling the use of larger datasets and improving the accuracy and speed of various applications.
