HyperNeRF
Since neural networks are universal, we can often solve problems we don't know exactly how to solve with neural networks. NeRF is a great example. But once solved, we should try to reverse engineer the solution and optimize.<p><a href="https://arxiv.org/abs/2112.05131" rel="nofollow">https://arxiv.org/abs/2112.05131</a> did such work and found you can get NeRF quality without any neural network at all and as a result 100x faster.
