The key to the solution mentioned in the paper is the utilization of neural network function approximations to extend Q-learning to large state and action spaces. This is achieved through the use of two neural networks: a policy network that is continuously updated and a target network that provides a stable target value. The target value is estimated using a loss function, with the loss function considered as the smooth L1-norm in this work .
How were the experiments in the paper designed?
The experiments in the paper "KANQAS: Kolmogorov Arnold Network for Quantum Architecture Search" were designed to evaluate the practicality of Kolmogorov Arnold Networks (KANs) in quantum architecture search problems . The experiments analyzed the efficiency of KANs in terms of the probability of success, frequency of optimal solutions, and their dependencies on various degrees of freedom of the network . In a noiseless scenario, the experiments showed that KANs had a significantly higher probability of success and generated a higher number of optimal quantum circuit configurations to produce multi-qubit maximally entangled states compared to multi-layer perceptron-based deep Q-networks . Additionally, in noisy scenarios, KANs demonstrated better fidelity in approximating maximally entangled states than multi-layer perceptrons, with the performance of the latter depending significantly on the choice of activation function . The experiments also revealed that KANs required a smaller number of learnable parameters compared to multi-layer perceptrons, but the average time of executing each episode for KANs was higher .
