Inter-relatedness of different financial instrument, i.e. financial networks, are often of strong interest, especially in market analysis. Currently, the financial networks are mainly constructed using the minimum spanning tree method or the maximally filtered graph method. Here we study a set of general coupled stochastic differential equations with correlation coefficients ρij. The thresholded values of ρij can be written as the entries in the adjacent matrix that represents the edges of a financial network. We use a simple generative adversarial network (GAN) method to recover the correlation coefficients. The discriminator of the GAN consists of a single layer artificial neural network. The dropout rate of the discriminator is set to 0.5 and using the sigmoid activation function. The generator of the GAN consists of two layers that have a fully connected perceptrons. The output layer uses an exponential linear unit activation function and the GAN encoder is a two-layer perceptron with ReLU activation function. The loss function used is the cross-entropy loss. The method is able to recover the given hand-crafted networks correctly. We also demonstrated the use of the GAN method to build a correlation network between currencies. The networks built are able to show progressive changes in the relationship between currencies over the years.Prices and volumes of financial instruments are often represented as stochastic processes.

This paper demonstrates a review in solving assembly line balancing problem by using metaheuristics hybridization. Generally, hybrid metaheuristic is a combination of two or more algorithms.

Hence this study has examined Job Demand, Workload, Time Pressure, Work Pressure, and Conflict at Workplace and Family-Work Conflict as the core dimensions to measure OS and also presenting an instrument of OS. This study adopted a cross-sectional research design, while quantitative data was collected from 129 Sewerage Operation workers across twelve states in Malaysia excluding Kelantan, Sabah and Sarawak, using structured survey. Based on the reliability testing, this study finalized the instrument to eighteen (18) items yielding three (3) dimensions, i.e., Job Demand (3 items), Workload (3 items) Time Pressure (3 items), Work Pressure (3 items) and Conflict at Workplace (3 items) and Family-Work Conflict (3 items). In this regard, researchers calculated the value of internal reliability (i.e., Cronbach Alpha value) for the current OS instrument.
