Over the past few years, engineered neural network training algorithms based on nature-inspired algorithms have demonstrated their efficacy in proving their dominance over many traditional algorithms. Using the population-based approach has significantly increased the accuracy of the neural artificial network and converged towards higher accuracy.

In machine learning algorithms, parameters and hy-perparameters are important properties in the training process. Parameters are modified through machine learning algorithms while hyperparameters are the parameters that are adjusted manually to achieve the desired accuracy and increase efficiency. In neural networks, weights are parameters while hyper-parameters include layer size, momentum, learn...Show More
In recent years many training algorithms for dynamic neural networks have been proposed. As a matter of fact, it is well known that the exact training algorithm for dynamic networks, is non causal and can be implemented only in batch mode.

Economic growth is an essential indicator in measuring a country’s economic development. The stability of the Rupiah exchange rate against the prices of goods and services is included in inflation. Another problem is an increase in the poverty rate. This happens because inflation tends to rise while people’s real income continues to decline, so people’s living standards also follow. This inflation...Show More
