To improve the quality of national education, the government through the Ministry of Education issued a certification policy. This is of course attractive for the community to be part of this program, many of whom choose to become teachers, even though they are not from higher education based education. One of the factors that attracts it is the allowances that will be obtained for teachers who have passed the certification exam. The government, through the Teacher Law, issues regulatory policies which later can be used as the basis for determining the eligibility of teachers as professionals, so that their profession is entitled to an allowance. However, conditions in the field were found that some teachers were not yet eligible to hold certification, because not a few scored below the standard Teacher Compotency Test (UKG). Therefore, in this study a system is proposed to be built using the Neural Network method and optimized with the Particle Swarm Otimation algorithm, to determine the feasibility of giving certification so that similar cases do not happen again. This study provides an overview that not all certified teachers deserve this predicate. The application of the Neural Network method which is optimized with the Particle Swarm Optimization algorithm, provides a higher accuracy with an accuracy rate of 99.70% compared to the neural network algorithm model of 99.60%.

In order to diagnose the fault in analog circuit correctly, a Wavelet Neural Network (WNN) method is proposed that uses the Particle Swarm Optimization (PSO) algorithm to optimize the network parameters. For the improvement of convergence rate in WNN based on PSO algorithm, a compressing method in research space is introduced into the traditional PSO algorithm to improve the convergence in WNN training. The simulation shows that the proposed method has a good diagnosis with fast convergence rate for the fault in analog circuit.

Prediction of bus arrival time is an important part of intelligent transportation systems. Accurate prediction can help passengers make travel plans and improve travel efficiency. Given the nonlinearity, randomness, and complexity of bus arrival time, this paper proposes the use of a wavelet neural network (WNN) model with an improved particle swarm optimization algorithm (IPSO) that replaces the gradient descent method. The proposed IPSO-WNN model overcomes the limitations of the gradient-based WNN which can easily produce local optimum solutions and stop the training process and thus improves prediction accuracy. Application of the model is illustrated using operational data of an actual bus line. The results show that the proposed model is capable of accurately predicting bus arrival time, where the root-mean square error and the maximum relative error were reduced by 42% and 49%, respectively.
