Hidden linear function problem
WebAbstract Recently, Bravyi, Gosset, and Konig (Science, 2024) exhibited a search problem called the 2D Hidden Linear Function (2D HLF) problem that can be solved exactly by a constant-depth quantum circuit using bounded fan-in gates (or QNC0circuits), but cannot be solved by any constant-depth classicalcircuit usingbounded fan-in AND, OR, and NOT … Web12 de jun. de 2016 · While the choice of activation functions for the hidden layer is quite clear ... This is because of the vanishing gradient problem, i.e., if your input is on a higher side ... so we use LINEAR FUNCTIONS for regression type of output layers and SOFTMAX for multi-class classification.

WebScience 362 (6412) pp. 308-311, 2024. The quantum circuit solves the 2D Hidden Linear Function problem using a *constant* depth circuit. Classically, we need a circuit whose depth scales *logarithmically* with the number of bits that the function acts on. Note that the quantum circuit implements a non-oracular version of the Bernstein-Vazirani ... http://www.seas.ucla.edu/~vandenbe/ee236a/lectures/pwl.pdf

A linear search function would have to make 10,600 comparisons to locate the value that is stored in the last element of an array. 2. Given an array of 1,500 elements, a linear search function would make an average of 1,499 comparisons to locate a specific value that is stored in the array. diaporthe celerisWebThe problem is to find such a vector z (which may be non-unique). 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 cities and municipalitiesWeb25 de ago. de 2024 · Consider running the example a few times and compare the average outcome. In this case, we can see that this small change has allowed the model to learn the problem, achieving about 84% accuracy on both datasets, outperforming the single layer model using the tanh activation function. 1.
