A Unitary Weights Based One-Iteration Quantum Perceptron Algorithm for Non-Ideal Training Sets
This work addresses a specific bottleneck in quantum machine learning for non-ideal training sets, offering an incremental improvement over existing quantum perceptron algorithms.
The authors tackled the problem of non-ideal training sets in quantum perceptrons by proposing a unitary weights-based algorithm that achieves one-iteration learning, accurately implementing arbitrary quantum gates with demonstrated advantages in applicability, accuracy, and availability.
In order to solve the problem of non-ideal training sets (i.e., the less-complete or over-complete sets) and implement one-iteration learning, a novel efficient quantum perceptron algorithm based on unitary weights is proposed, where the singular value decomposition of the total weight matrix from the training set is calculated to make the weight matrix to be unitary. The example validation of quantum gates {H, S, T, CNOT, Toffoli, Fredkin} shows that our algorithm can accurately implement arbitrary quantum gates within one iteration. The performance comparison between our algorithm and other quantum perceptron algorithms demonstrates the advantages of our algorithm in terms of applicability, accuracy, and availability. For further validating the applicability of our algorithm, a quantum composite gate which consists of several basic quantum gates is also illustrated.
