Error magnitude and directional accuracy for time series forecasting evaluation
Evaluation of forecast accuracy is very much influenced by the choice of accurate measurement since it can produce different conclusion from the empirical results. Thus, it is important to use appropriate measurement in accordance to the purpose of forecasting. Commonly, accuracy is measured in …

Motor control and directional accuracy of phonotaxis in female field crickets
… descending from the brain. Finally, I tested the accuracy of female crickets walking on a trackball as they performed phonotaxis towards a speaker oscillating constantly between 45° left and 45° right relative to their long axis. In a group of crickets, I used a drop of wax to fix the prothorax …

Empirical Analysis of Neural Architectures and Side Information in Financial Time Series Forecasting
… input features improve both error metrics and directional accuracy; (2) a comparison study of four training methods (one-step-ahead, direct multi-step, simulation error, and teacher-forcing); (3) the development of a bidirectional GRU-LSTM hybrid model that outperforms standard recurrent …

A Simulation Model to Analyze the Impact of Golf Skills and a Scenario-based Approach to Options Portfolio Optimization
… of various skills (e.g., driving distance, directional accuracy, putting skill, and others) on golf scores. The golf course model includes realistic features of a golf course including rough, sand, water, and trees. Golfer shot patterns are modeled with t distributions and mixtures of t and …

Directional Perception of Force in a Virtual Reality Environment
… in understanding the impact of motion on the directional accuracy of force perception, as observed in a VR environment. We used a custom force-feedback system that pulled a handle with a force of 1.87N at various angles in front of N=14 subjects. The virtual environment showed a curved wall, …

Economic evaluation of financial forecasting
… but very few in absolute value Only the directional accuracy exhibits high degree of linear association with profits When the true Gaussian process is not known, there are cases for which a decrease in mean squared error does not imply an increase in returns Therefore the mean squared …
