Efficient Approximation

Efficient approximation methods aim to reduce the computational cost of complex calculations while maintaining acceptable accuracy. Current research focuses on developing faster algorithms for tasks like Earth Mover's Distance computation, Shapley value estimation, and approximating solutions to partial differential equations such as the Navier-Stokes equations, often leveraging techniques like nearest neighbor search, kernel density estimation, and functional decomposition. These advancements are crucial for scaling up machine learning models, improving the efficiency of computer vision and other applications, and enabling real-time analysis of large datasets in various scientific domains.
