Randomized Approximation

Randomized approximation techniques aim to efficiently estimate computationally expensive quantities by employing probabilistic methods, offering a trade-off between accuracy and speed. Current research focuses on developing and analyzing these methods for diverse applications, including estimating statistical distances (like total variation distance and Tukey's depth), accelerating simulations (such as room impulse response modeling), and approximating matrix operations (e.g., for Renyi's entropy). These advancements are significant because they enable the analysis of large-scale datasets and complex systems that would otherwise be intractable, impacting fields ranging from machine learning and signal processing to statistical inference.
