The helicity modulus Υp is suppressed with phase slippage, and its suppression is found to be well described with the scaling form obtained from the Tomonaga-Luttinger liquid theory in the one-dimensional limit. Applied Soft Computing, 55: 211–225. \oddsidemargin -1.0in Due to the different types of neurons in the reserve pool and the different characteristics of the data, the input signal needs to be scaled by the reserve cell input unit size IS to be transported from the input layer to the reserve pool.

The Kosterlitz-Thouless (KT) transitions for the two-dimensional (2D) XY and q-state clock models are studied by using the PCC algorithm. reported optimization of double layer ESN by genetic algorithms and applied the optimized model in multi-area time series prediction (Zhong et al. \usepackage{amssymb} Time series prediction using dynamic Bayesian network. The prediction model optimizes the echo state network, improves the accuracy of time series prediction, and shortens the prediction time to some extent. Subscription 2017), PSO optimization based ESN model (denoted as PSO_ESN) (Zhang et al. Learn More ». Table 3 shows the comparison of the running time of the six predictive models on different datasets. The experimental effect is worthy of further study and discussion. We have compared our results obtained from one-dimensional random walk for the XY model with those obtained from the standard Metropolis algorithm to check the accuracy of our The internal connection weight spectrum radius of the reserve pool is a key parameter of the reserve pool, affecting its memory capacity. Instead, a single cluster is built. Stars represent ΔE′(1/2)=E1/2−E1 for N=4×4×160. Second, the GWO-ESN model shows excellent fitting effectiveness for all data sets, while the PSO-ESN model is inferior for history data sets but its effectiveness still satisfies the requirement. The coefficient vector is defined as follows: where r1 and r2 are random vectors with values in [0, 1] and a is the iteration factor. See Off-Campus Access to Physical Review for further instructions. 2017) have been proposed and widely applied in nonlinear time series predictions. A Wolff-type cluster Monte Carlo algorithm for random magnetic models is presented. refers to the prediction value, y refers to the measured value, n refers to the data length. This can be attributed to data characteristics and parameter setting. and XIdM5 Plos One, 12(1): e0161501. Step2: Initialize parameters in ESN and Grey Wolf algorithm. Herein, prediction results by the proposed GWO_ESN model were highly fitted with practical results and the amplitudes were relatively small, indicating high prediction accuracy of the proposed model. Among them, the size of the reserve pool N is reflected by the number of neurons. \usepackage{mathrsfs} Sign up to receive regular email alerts from Physical Review B.

Therefore, the prediction performance of the proposed GWO_ESN time series prediction model is considered to be optimized.

COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. 2017. Wout of ESN was optimized using the Grey Wolf algorithm and predictions of time series data were achieved using simplified training.
