Researchers have introduced a new framework for random feature learning, extending it to Banach spaces. This approach allows for significant reductions in computational complexity by only training a linear readout after random initialization of feature maps. The study proves a universal approximation result within the corresponding Bochner space and derives approximation rates, offering an explicit algorithm for learning elements in the Banach space. This framework encompasses random trigonometric regression and random neural networks, extending their universal approximation properties to various function spaces, including those over non-compact domains.
