It is important to evaluate forecast accuracy using genuine forecasts. That is, it is invalid to look at how well a model fits the historical data; the accuracy of forecasts can only be determined by considering how well a model performs on new data that were not used when estimating the model. When choosing models, it is common to use a portion of the available data for testing, and use the rest of the data for estimating (or “training”) the model. Then the testing data can be used to measure…

An Autoregressive Neural Network model is proposed for forecasting daily spot gas prices and shows an improvement of around 33% over ARIMA in terms of mean squared error when price forecasts are used in gas purchase decisions.

Hierarchical forecasting of engineering demand at KLM Engineering & Maintenance

A framework that applies multiple models and leverages the benefits of forecast combination and reconciliation to enable aligned decisions for capacity on both tactical and operational levels is proposed and testing the proposed framework indicate that significant improvements are possible.

Forecasting Electricity Generation Capacity in Malaysia : An Auto Regressive Integrated Moving Average Approach

It is imperative for Malaysia to have a clear understanding of the future performance of its power sector with emphasis on the total installed capacity variable as this is integral to support the

Stock Market Volatility Modeling and Forecasting with a Special Reference to BSE Sensex

This study is intended to investigate the volatility patterns in Bombay Stock Exchange Limited Sensitivity Index (BSE Sensex) based on time series data collected for 10 years period of time. To reach

Bayesian enhanced ensemble approach (BEEA) for time series forecasting

Relative advantages and limitations of the ensemble approach in contrast with some reported in the literature are illustrated to highlight the effectiveness of the Bayesian enhanced ensemble approach (BEEA) through different forecasting horizons.

Comparison of Classical and Nonlinear Models for Short-Term Electricity Price Prediction

Two contrasting machine learning approaches for predicting electricity prices, regression decision trees and recurrent neural networks, are tested and found to achieve high performance, suggesting that regression trees should be more carefully considered for electricity price forecasting.

A Novel Method for Sea Surface Temperature Prediction Based on Deep Learning

A novel model of SST prediction integrated Deep Gated Recurrent Unit and Convolutional Neural Network (DGCnetwork) is proposed, which has a compact structure and focuses on learning deep long-term dependencies in SST time series.
