Abstract: A method for analyzing experimental data related to quantum system by using neural network by an electronic device is provided. The method includes: generating a training dataset according to experimental data; performing one or more filtering operations on the training dataset to generate one or more filtered training datasets respectively corresponding to the filtering operations; training a first neural network and a second neural network by inputting the original and filtered training datasets; evaluating the first and the second neural network; obtaining one or more classification accuracies of the first and the second neural network; identifying the differences between pairs of classification accuracies; and determining impact level of each information preserved or removed by each of the filtering operations according to the differences.
