Not just partially, xorshift128 is designed such that the output depends only on the last 4 results. So this is "just" learning the output function of xorshift as a neural network.
- SeanLuke 5y agoPerhaps you might consider how big that output function ideally is, then compare to the capacity of the neural network they used and the number of samples provided.
- _hl_ 5y agoMy reading of it is that it's essentially one-to-one (up to minor constant factors), they took the binary circuit for xorshift128 and replace the xor gates by functionally equivalent NN blocks, and then trained the weights.
