Web28 de fev. de 2024 · The code self.hidden = nn.Linear (784, 256) defines the layer, and in the forward method it actually used: x (the whole network input) passed as an input and the output goes to sigmoid. Also, not sure if it's not clear, but hidden is just a name and has no special meaning. It could be called inner_layer or layer1. http://www.seas.ucla.edu/~vandenbe/ee236a/lectures/pwl.pdf

The hidden linear function problem, is a search problem that generalizes the Bernstein–Vazirani problem. In the Bernstein–Vazirani problem, the hidden function is implicitly specified in an oracle; while in the 2D hidden linear function problem (2D HLF), the hidden function is explicitly specified by a matrix and a binary vector. 2D HLF can be solved exactly by a constant-depth quantum circuit restricted to a 2-dimensional grid of qubits using bounded fan-in gates but can't be solved by an… Web1 de jan. de 2001 · Quantum Cryptanalysis of Hidden Linear Functions ... We show that any cryptosystem based on what we refer to as a ‘hidden linear form’ can be broken in quantum polynomial time. Our results imply that the discrete log problem is doable in quantum polynomial time over any group including Galois fields and elliptic curves. sheq international

This problem can be viewed as an non-oracular version of the well-known Bernstein-Vazirani problem [17], where the goal is to learn a hidden linear function speciﬁed by an oracle. In our case there is no oracle and the linear function is hidden inside the quadratic
