Forecasting Gold Price in Rupiah using Multivariate Analysis with LSTM and GRU Neural Networks

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 2, Page # 245–253, 2021; DOI: 10.25046/aj060227
Abstract:

Forecasting the gold price movement’s volatility has essential applications in areas such as risk management, options pricing, and asset allocation. The multivariate model is expected to generate more accurate forecasts than univariate models in time series data like gold prices. Multivariate analysis is based on observation and analysis of more than one statistical variable at…

Modeling an Energy Consumption System with Partial-Value Data Associations

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 6, Page # 372–379, 2018; DOI: 10.25046/aj030645
Abstract:

Many existing system modeling techniques based on statistical modeling, data mining and machine learning have a shortcoming of building variable relations for the full ranges of variable values using one model, although certain variable relations may hold for only some but not all variable values. This shortcoming is overcome by the Partial-Value Association Discovery (PVAD)…
