Researchers have developed a novel method using neural networks to learn and optimize orthonormal bases for function spaces. This approach allows bases to adapt to specific datasets or problems, unlike fixed bases like Fourier or wavelets. The technique models orthonormal bases as paths on a Lie manifold, driven by ordinary differential equations parameterized by neural networks. The study demonstrates that even with low-rank generators, these neural network-defined paths can approximate any target orthonormal basis, showing flexibility in applications like principal component analysis and physical simulations.
